Preface
T
his guidebook to the trees planted in the Washington SyCip Garden of Native trees on the campus of the University of the Philippines in Diliman is part of a generous donation given by the Zuellig Group in honor of Washington SyCip. The purpose of this book is to help secondary school students and other interested individuals recognize and appreciate our native trees. The featured species represent a small fraction of the thousands of indigenous and endemic plants found throughout our archipelago. This study guide for our campus trees will not leave the reader guessing, because each tree described is properly designated in the garden itself. Many other species of native trees are to be found on the U.P. Diliman campus, with more and more being added as the university decided nearly five years ago, at the start of its second century of existence, to adopt a native tree planting policy. We aim to highlight the immense and exciting biodiversity of Philippine terrestrial habitats, with a special focus on trees. This biodiversity provides ecosystem services which every high school student should learn and appreciate, so as to contribute to protecting our rich natural heritage which in turn supports livelihoods and human life. Bear in mind that this should be considered as only a start. It is hoped that students, citizens and visitors will use the experience of visiting the garden to learn more about the 101 species planted there through this guidebook and to develop a better appreciation for nature and care for it, for themselves and for future generations.

Message
T
oday’s youth will do well to study the lives of people who have made great contributions to the development of our country, be they historical heroes, political leaders or captains of industry. Included in this illustrious list is Washington SyCip, whose eminent role in the advancement of the accounting profession in the Philippines and business administration has moved his friends and associates to celebrate his legacy in various memorials such as this garden. Equally important, our youth should learn about the rich natural resources of our great country, including our botanical heritage. It is a tragedy that earlier generations have abused our trees to the point of our near-extinction; it is unfortunate that very few of us are even familiar with native trees. It is time to increase our awareness of the unique biodiversity of our land to inspire us to be better stewards of these natural resources. The San Beda College Alumni Foundation is proud to participate in the National Greening Program of the Department of Education and to assist government’s efforts to designate areas as appropriate planting sites. Together with the University of the Philippines and the Zuellig Group, we share a vision of a clean and healthy environment and the pursuit of sustainable development. We are indeed happy that the Zuellig Group, as a corporate entity, has sponsored the planting of more than 100 species of native trees in the UP Diliman campus. We hope that more companies and individuals join us in the advocacy that the noted Filipino botanist Leonard L. Co pioneered and worked for till his dying breath: “Love all, but plant only native trees.”

Why Native Trees?
I
f the goal is to plant trees and cover bare ground, then does it make a difference whether we plant the foreign mahogany from Bolivia rather than molave or any other trees native to the Philippines? Yes, it makes an enormous difference and the reason, in one word, is ecology. Molave, as a native species, has a relationship to the land, water and other organism that has developed over a million years. Certain fungi live with the roots; certain insects feed on the plant parts, while others pollinate the flower. Birds and mammals live along the branches and feed on the seeds. No such relationship exists for the newcomer. Ten hectares of mahogany is a “dead zone’ in terms of biodiversity. There are no birds, no insects, only a nearly dead soil due to the lethal chemicals that leak from the rotting leaves. Native species are rarely found as seedling beneath the canopy and so, most significantly, there is no future for ten hectares of mahogany. It will remain as it is until it is cut and replaced. The alternative to plantations of alien species is to rebuild our forests with native species. Such schemes have been practiced for centuries by many Southeast Asian indigenous communities and aim to imitate the natural succession of forests as they recover from typhoon or fire. Bare ground is first occupied by the hardy pioneers that thrive in the full sun. Birds of the forest margin then bring in seeds of the fruit-bearing shrubs and other smaller trees that provide a layer of shade, within which the seedlings of the larger canopy trees will begin life. With advancing shade the pioneers must find a new home in gaps and along the forests margins, and thus begins again the cycle of forest collapse and renewal. The challenge in reforestation with native species lies in the immense richness and diversity of our Philippine flora: perhaps 10,000 different kinds of flowering plants and 3,600 native trees. Which ones to choose? And what are the requirements for optimal growth? This little book is filled with examples of plants native to the Philippines that can contribute to our endeavor of possessing our uniquely diverse natural environment. The result for our children and their children will be forests that grow and mature over decades and change in a way that guarantees centuries of social and economic service to our people. JAMES V. LaFRANKIE Ph.D. EDC Professor of Plant Diversity, UP Diliman Author of Trees of Tropical Asia: An illustrated guide to diversity

How to Use This Guide
I
f you are a visitor in the Washington SyCip Garden of Native Trees: Mabuhay! There are few places in the metropolis where you can see such a large number of native tree species. This little guidebook to the Washington SyCip Garden of Native Trees is not a reference book; it is merely a map to the 101 native trees (99 trees and 2 palms) in this collection of native tree species. The Washington SyCip Garden of Native Trees (WSGNT) was envisioned to honor a man who personifies what many of our native trees stand for: strength, usefulness, endurance, resilience and majesty. Washington SyCip founded the country’s largest multi-disciplinary professional services firm (SGV). He helped shape Philippine business just as our native trees define our biological heritage. The area along Magsaysay Avenue in the UP Diliman Campus, where the WSGNT now stands, was an empty parking lot until 2012. WSGNT may showcase just a small portion of collection of 3,600 native tree species but it is a start. Like a small seed that grows into a mighty tree, this small park may inspire many Filipinos to plant native trees to save our environment. As you walk through the WSGNT, take note of the red, brick path that meanders through the “islands”. The islands host one, two or several tree families represented by their respective members. Plant families are Latin words that end with –ceae (i.e., Euphorbiceae, Phyllanthaceae). Plant families are like our own extended families consisting of brothers, sisters, cousins. These are identified by their scientific names. Scientific names are two Latin words that are always italicized. The first word, whose first letter is capitalized, is the genus (similar to our family name). The second word, written in lower case, is the species name (like our given first name). A species name could describe certain characteristics or features of the species, like Cananga odorata, so called because of its odorous, fragrant flowers; or it could indicate the origin of the species where it was first recorded, like Cinnamomum mindanaense (in Mindanao); or it could honor a certain person, as in Adonidia merrillii, named after Dr. Elmer Merrill, a reknowned botanist. One scientific name refers exclusively to one particular species. But one local name could refer to several different species, and different local names could refer to just one tree species (i.e. narra is naga in the Bicol region and angsana in Singapore and Malaysia, but XI
all refer to it as Pterocarpus indicus). Note that “species” is used for both singular and plural forms. This book will make it easier for you to locate each tree in the Garden and will give you the basic information about each tree, as follows:

Ecological classification Status Size: Optimal height and trunk size Type Natural habitat Tree tales
The number on the upper edge of each page will lead you to the location of each tree within the garden. It also corresponds to the number indicated on the tree marker The following colors indicate the primary purpose for growing each tree: for its edible fruits for its blooms for its foliage for its timber for economic, medicinal and other uses
p q XII
The ‘title’ of each page carries the official local name of the tree featured (i.e. Mangkono). The featured tree Scientific name (i.e. Xanthostemon verdugonianus).

The third line consists of the following: the family (Myrtaceace); the ecological classification (endemic or indigenous: indigenous trees are trees native also to other countries within our climatic zone; endemic tree species, on the other hand, are found only in our country); lastly, the tree status as defined by DAO 2007 of the DENR (from critically endangered to vulnerable). The tree sizes as indicated are the maximum sizes the trees attain in their natural habitat: • Small tree: 3m to 8m • Medium-sized tree: 8m to 16m • Large tree: 16m and higher “Type” will indicate whether the tree is evergreen (trees that always have leaves), deciduous (trees that shed their leaves periodically and become bare), or semi-deciduous (somewhere between an evergreen and deciduous). Some tree species have male and female plants (dioecious), like the himbaba-o or the pili (although pili is not featured in the garden). “Habitat” indicates the tree’s natural home. For most species, the original habitat is in forests. However, like domesticated animals, most of the featured tree species will live and thrive in urban areas. “Tree Tales” are notes about the featured tree species, such as information about medicinal and economic uses and explanations of the origin of names (Latin or Filipino name).
Enjoy and learn from the WSGNT with this guidebook. We hope that you will be inspired to plant your own little garden of native trees; even if you have time and space for only one tree, you will have done your part in preserving our biological heritage. Finally, a blessing from St. Francis of Assisi “…may God bless you with enough foolishness to believe that you can make a difference in the world, so that you can do what others claim cannot be done.” IMELDA P.

Binunga
Macaranga tanarius
EUPHORBIACEAE • Indigenous
SIZE: Up to 8m tall; trunk size 25cm diameter TYPE: Evergreen HABITAT: Thickets, wasteland, open spaces and second-growth forests at low and medium altitudes
2
The binunga is suitable for the natural regeneration of deforested land as it is a fast-growing pioneer species. In southern Sumatra binunga has been used by pepper growers to make temporary ladders to harvest the crop. Its wood was popular for making the once-ubiquitous bakya (wooden clogs). A decoction of the binunga’s root-bark may be applied topically on wounds, but not including its sap, which is sticky as glue.
Malabagang Glochidion album
03
PHYLLANTHACEAE • Indigenous
SIZE: Up to 3m tall TYPE: Evergreen HABITAT: Primary forests at low and medium altitudes
Malabagang means “molar-like,” and this tree’s curious-looking, yellow-green fruits have the size and appearance of molars, including parallel grooves. Malabagang wood is prized as fuel.

Alim
Melanolepis multiglandulosa
EUPHORBIACEAE • Indigenous
SIZE: Up to 20m tall; trunk size 20cm diameter TYPE: Evergreen HABITAT: Re-growth thickets, roadsides; in primary forests at low and medium altitudes
4
Alim is a drugstore of sorts. Its leaves, when ground with ginger, serve as an ointment to treat dandruff and flaking skin; when dried and crushed, it may be taken with cold water to treat constipation, tuberculosis and chest pains. It is said to be powerful enough to shock worms out of infested bodies. Its tiny clustered fruit is a favorite food for many bird species.
Bignay Pugo Antidesma pentandrum
05
PHYLLANTHACEAE • Indigenous
SIZE: Small tree up to 3m tall TYPE: Evergreen HABITAT: Secondary forests, thickets and open rocky ground; very resistant to drought

Bignay
Antidesma bunius
PHYLLANTHACEAE • Indigenous
SIZE: 3 to 10m tall; trunk size 20cm diameter TYPE: Evergreen HABITAT: Thickets and open slopes, in towns and communities and occasionally in forests from northern Luzon to Mindanao
6
The bignay’s cascading cherry-like fruits are green when young, and turn to red and deep purple when ripe. You might want to harvest bignay fruits before the birds get them! Substitute the green fruits for vinegar when cooking sour dishes (sinigang! paksiw!); preserve the red ones as jam or as wine or juice to ease a fever; and eat the purple ones with a sprinkling of salt to be fortified with iron.
Bignay Kalabaw Antidesma pleuricum
07
PHYLLANTHACEAE • Endemic • Limited Distribution
SIZE: Up to 5m tall; trunk size 25cm diameter TYPE: Evergreen HABITAT: Primary lowland forests in Luzon, Burias, Samar, Siargao, Mindanao
Traditional Filipino healers immerse and crush bignay berries in a glass of water as a potent drink to bring down a fever. Very rich in anti-oxidants, bignay berries rival their foreign counterparts in usefulness and size. Mabuhay ang sariling atin! Unknown to many of us, the Philippines has 24 different species of bignay, of which more than half are found only in our country. But due to its limited distribution and the destruction of habitat, this species could become endangered. 7
08
Mangkono
Xanthostemon verdugonianus
MYRTACEAE • Endemic • Endangered
SIZE: Up to 25m tall; trunk size 80cm diameter TYPE: Evergreen HABITAT: Very limited habitat mainly Dinagat Island, Surigao, Homonhon Island in Samar, Leyte, Palawan and Sibuyan; usually near seashores in ultrmafic soil
8
The mangkono is described as nature’s superstar for its lovely red and white flowers. It is also known as the Philippine “ironwood” for its luxurious timber of extraordinary density. It attains a 7 cm diameter after only ten years. It grows best in soil where minerals like copper and nickel are present. Mangkono wood sinks in water and is immune from termites.
Malabaltik Syzygium affine
09
MYRTACEAE • Endemic
SIZE: A medium-sized tree up to 20m tall TYPE: Evergreen HABITAT: Found in Nueva Ecija, Bulacan, Rizal, Quezon and Sorsogon
The Filipino word “baltik” means “a fit of anger” or “bad temper.” Malabaltik wood is prized among house builders, carpenters and furniture makers all over Luzon. It is sturdy enough for posts, poles, window sills, flooring, implements and fiber board.

Syzygium merrittianum
MYRTACEAE • Endemic • Limited distribution
SIZE: Up to 20m tall; trunk size 70cm diameter TYPE: Evergreen HABITAT: Luzon, Mindoro, Sibuyan Island; in forest slopes and along streams at low and medium altitudes
10
Its clusters of fluffy and showy strawberry-pink flowers make this a lovely ornamental tree. True to its genus, the tumolad is a medium to heavy hardwood used for house construction as posts and poles.
Makaasim
11
Syzygium sp.
MYRTACEAE • May be endemic
SIZE: Up to 20m tall; trunk size 25cm diameter TYPE: Evergreen HABITAT: Sibuyan Island along the coasts
Syzygium is one of the most robust genera in the plant kingdom. Consisting of hundreds of species, the non-native trees duhat, makopa and tampoy, as well as the native igot, lipote and hagis, all belong to this species. The fruits of both these native and non-native trees are edible, many of them sour; hence the name.
11
Hagis
12
Syzygium tripinnatum
MYRTACEAE • Endemic • Limited distribution
SIZE: Up to 20m; trunk size 25cm diameter TYPE: Evergreen HABITAT: From Luzon to Mindanao; in primary forests at low to medium altitudes
12
This native fruit tree has clustered whitepinkish flowers that are showy when in full bloom. Its fruit looks like the fruit of the non-native macopa in shape and color. The hagis fruit may be eaten raw or made into juice, jam or jelly.
Puso-Puso
Actinodaphne multiflora
13
LAURACEAE • Indigenous
SIZE: Up to 25m tall; trunk size 20cm diameter TYPE: Evergreen HABITAT: Mindoro, Guimaras, Basilan, Mindanao; in primary forests at low and medium altitudes
The puso-puso tree is known for its leaves which, when mixed with mortar, yield a glutinous substance that produces strong glue. Because of its leaf groupings, the Malaysian name for this species is “payong”, which means umbrella in both Bahasa and Filipino. Like many umbrellas, its underleaf is a lighter shade than its topside.
13
14
Sablot
Litsea glutinosa
LAURACEAE • Indigenous
SIZE: Up to 20m; trunk size 60cm diameter TYPE: Deciduous HABITAT: Secondary forests and thickets at low and medium altitudes
14
Sablot is a member of the aromatic laurel family of trees whose leaves are used in cooking adobo. The oil from its seeds are used to make candles and soaps. A row of sablot trees may be seen on the middle island of Padre Burgos, which stretches for 200 meters from Roxas Boulevard.
Marang Laparan Litsea grandis
15
LAURACEAE • Indigenous
SIZE: Up to 30m tall; trunk size 80cm diameter TYPE: Evergreen HABITAT: Common in lowland to mountainous forests and in peat swamps
Marang laparan is an important source of light to medium weight hardwood for sturdy furniture and wood carving.

Marang) 16 Malaabukado (aka Litsea cordata LAURACEAE • Indigenous
SIZE: Up to 36m tall; trunk size 25cm diameter TYPE: Evergreen HABITAT: Primary and secondary forests along rivers, in swamps, also in hill forests
16
There is some confusion with this tree’s name. For botanists the official name of the species is “marang,” but this is not to be confused with the native fruit that competes with the durian in taste and smell, named by the botanists marang banguhan. Malaabukado/marang wood is used for light construction, for interior finishing and cabinets.
Kalingag
Cinnamomum mercadoi
17
LAURACEAE • Endemic • Vulnerable
SIZE: Up to 30m tall; trunk size 60cm diameter TYPE: Evergreen HABITAT: Throughout the Philippines in lowland and mountainous forests
Cinnamomum, also known as camphorwood, is mentioned in several biblical passages. One of the Philippines’ endemic cinnamons, kalingag boasts of a long list of medical uses. Its cinnamon is used to brew root beer.
17
18
Patalsik Pula Decaspermum blancoi
18
MYRTACEAE • Endemic
SIZE: 12m tall TYPE: Evergreen HABITAT: Throughout the Philippines; in lowland and mountainous forests; along streams and in swamp forests
Patalsik-pula enhances gardens and roadsides with its beautiful blooms. Its name already evokes the splendour of its attractive flowers. In Java the species is found as second storey in forestry plantations. Although hardly logged for its timber, its wood can be used to produce small objects like tool handles and rice pounders.
19
Cinnamon 19 Mindanao Cinnamomum mindanaense LAURACEAE • Endemic
SIZE: Up to 10m tall; trunk size 20cm diameter TYPE: Evergreen HABITAT: Surigao, Davao, Zamboanga; in lowland and mountainous forests
20
Among the cinnamons, the bark of this species is considered one of the best found in the Philippines. It can be brewed into a fresh and nutritious breakfast drink.
Lagunding Dagat Vitex trifolia
20
LAMIACEAE • Indigenous
SIZE: A treelet that grows from 1.4m to 4m TYPE: Evergreen HABITAT: Along the seashores
The lagunding dagat, whose scientific name refers to its cluster of three leaves, can be compared to basketball’s 3-point clincher, not just for its numeric association but in terms of its importance. Like its sibling lagundi, it provides a potent cure to various ailments.
21
21
Alagau
Premna odorata
LAMIACEAE • Indigenous
SIZE: Up to 20m tall; trunk size 80cm diameter TYPE: Evergreen HABITAT: Thickets and secondary forests at low altitudes
22
Insects that prey on dengue-carrying mosquitos are attracted to the fragrant alagau which has become their natural habitat. Steeped in hot water, the leaves are also a good cure for coughs. Plant an alagau tree in your backyard and be rewarded with a dengue-free zone, cooking condiments, a fragrant environment and a beautiful tree.
Molave
Vitex parviflora
22
LAMIACEAE • Indigenous
SIZE: Up to 20m tall; trunk size 80cm diameter TYPE: Deciduous HABITAT: Secondary and open primary forests over limestone and seasonally dry forest and sometime along the sea coast
This tree must have made a great impressison on President Manuel L. Quezon, who said in his speech: “I want our people to be a molave tree. Strong and resilient, standing on the hillside and unafraid of the rising tide, lightning and the storm, confident of its strength.” Molave timber is tough and durable, used for high grade construction and woodcraft. It is a source of pride among Filipino homeowners if their houses and furniture are made of molave.
23
23
Bolon
Platymitra arborea
ANNONACEAE • Endemic • Rare
SIZE: Up to 40m tall; trunk size 80cm diameter TYPE: Evergreen HABITAT: Luzon, Leyte, Cebu and Mindanao; in primary lowland rainforests
24
Bolon is one of the trees described by Father Blanco in his book Flora de Filipinas. The religious connection does not end there. The tree’s latin name Platymitra is Greek for flat-mitre, referring to the shape of the petals that resemble bishop’s headdress. The bolon wood is regarded as a substitute for hard maple. There are only two species in the genus Platymira: One variety is found in other Southeast Asian countries, whereas bolon is found only in the Philippines.
Ilang-Ilang
24
Cananga odorata
ANNONACEAE • Indigenous
SIZE: Up to 20m tall; trunk size 60cm diameter TYPE: Evergreen HABITAT: Forested areas up to 800m altitude
Ilang-ilang (or ylang-ylang) blooms perfume many a Filipino memory. The curly and fragrant flowers dangle at the end of beautiful leis presented to loved ones, dignitaries and religious icons. In Australia, the ilang-ilang tree is used for rainforest regeneration due to its fast growth and fauna-attracting fruit. On the coast of East Africa, ylang-ylang plantations produce tons of flowers which are harvested and dried to make perfume, such as the famous Chanel No. 5.
25
25
Yellow Lanutan
Polyalthia flava
ANNONACEAE • Endemic
SIZE: Up to 20m tall; trunk size 20cm diameter TYPE: Evergreen HABITAT: Throughout the Philippines; in forests at low and medium altitude
26
This tree is known by different names: duhat-matsing, baling manok, duhatduhatan, tagputagpuan. A famous member of this genre is the Polyalthia longifolia, known locally as the Indian tree or the cemetery tree, an introduced species. Yellow lanutan timber is dry and termite-resistant, making it a popular choice for building houses.
Lingo-lingo
Viticipremna philippinensis
26
LAMIACEAE • Indigenous • Rare
SIZE: Up to 25m tall; trunk size 80cm diameter TYPE: Evergreen HABITAT: Primary lowland forests
The lingo-lingo tree is a tragedy in the making. It is known to be a fast growing species that is perfect for reforestation. However, it is heavily depleted due to habitat destruction and is in serious danger of genetic erosion. Unless this trend is reversed, the Philippines would be deprived of its wood, which is used for construction, musical instruments, and household and agricultural implements.
27
27
Amuyong
Goniothalamus amuyon ANNONACEAE • Endemic • Rare
SIZE: Up to 15m tall; trunk size 20cm diameter TYPE: Evergreen HABITAT: Ilocos Norte, Ilocos Sur, Abra, Pangasinan, Quezon, Rizal, Batangas, Negros, Bohol, Mindanao; in forests at low and medium altitudes
28
The Hanunuo Mangyan tribe of Mindoro burns fresh amuyong bark to control rice bugs and corn borers. The bark is used to weave ropes in an attractive apricot-buff color. Amuyong seeds are cooked with oil and used as liniment for rheumatism, while its fruit is used as medicine to ease stomach ache.
Bagawak Morado Clerodendrum quadriloculare
28
LAMIACEAE • Indigenous • Critically endangered
SIZE: Up to 8m tall; trunk size 6cm diameter TYPE: Evergreen HABITAT: Primary and second-growth forest at low and medium altitudes
This is a good candidate to be the official tree of the University of the Philippines. Its leaves are deep green with maroon undersides, in perfect consonance with the university colors. It is a small ornamental tree with festive blooms and striking foliage. Butterflies love its nectar. Boholanos call it pebrero because it blooms in February, while others call it the “Mexican firecracker” because its pink flowers, with its long tubular throats appear like exploding fireworks.
29
30
Tangisang Bagyo Xylopia densifolia
29
ANNONACEAE • Endemic
SIZE: Up to 18m tall; trunk size 20cm diameter TYPE: Evergreen HABITAT: Throughout the Philippines; in forest at low and medium altitudes
Such a sad name for a tree: Tangis is “grief” in Filipino, bagyo means “typhoon”, and its scientific name Xylopia means bitter-wood in Greek. The genus Xylopia in the Annonaceae family is the only genus that is shared among Asia, Africa and America with 160 species.
31
30
Lagundi
Vitex negundo
LAMIACEAE • Indigenous
SIZE: Up to 8m tall; trunk size 5-8cm diameter TYPE: Evergreen HABITAT: Near bodies of water, disturbed land, grasslands and mixed open forests
32
The different parts of the wondrous lagundi tree may be used to cure any of the following ailments: colds, flu, bronchial asthma, chronic bronchitis and pharyngitis. Lagundi products are among the ten herbal medicines acknowledged by the Philippine Department of Health to have proven therapeutic value. Lagundi is also used by agriculturists to protect stored garlic from pests.
Kalimatas
Phaeanthus ebracteolatus
31
ANNONACEAE • Indigenous
SIZE: Up to 7m tall; trunk size 20cm diameter TYPE: Evergreen HABITAT: Widely distributed in the Philippines; in primary and secondary forests
Kalimatas contains the syllables “mata”, the filipino word for eye. Coincidentally, the bark solution of this species is popular for treating sore eyes. It may also be used as an antispasmodic, a cure for ulcers and small wounds.
33
Philippine Teak
32
Tectona philippinensis
LAMIACEAE • Endemic • Critically endangered
SIZE: Up to 15m tall; trunk size 5cm diameter TYPE: Deciduous HABITAT: Luzon with San Juan and Lobo, Batangas as its natural habitat; also found in Iling Island, Mindoro; in thickets and secondary forests at low altitudes

The tree’s local name, malapangit, does not do it justice. Philippine teak produces a bonanza of bluish to purple/lilac blooms in summer. The tree’s other folk name, malabayabas, is more appropriate because its flaky and thin bark is similar to the guava tree. Its scientific name Tectona refers to the Greek word for carpenter. Teak wood was used to build and repair galleon ships during the Spanish colonial era.

Baraibai
Cerbera manghas
APOCYNACEAE • Indigenous
SIZE: Up to 15m tall; trunk size 50cm diameter TYPE: Evergreen HABITAT: Coastal areas
76
“The sweet fragrance of the blooms compensates for the poisonous nature of the large, ruby-red, lacquered fruit, the oily seeds of which are reported to contain the heart poison, cerebin... (Hence) the name Cerbera alludes to the toxic nature of the plant and derives from Cereberus, the name of the three-headed dog from Greek mythology that guarded the entrance to Hades, the underworld.” Margaret Barwick “Tropical and Subtropical Trees”
Dita
75
Alstonia scholaris APOCYNACEAE • Indigenous
SIZE: Up to 50m tall; trunk size 100cm diameter TYPE: Evergreen HABITAT: Almost sea level and open mountain slopes at about 1000m altitudes

Diospyros ferrea
EBENACEAE • Indigenous • Vulnerable
SIZE: Up to 30m tall; trunk size 50cm diameter TYPE: Evergreen HABITAT: Found in evergreen forests in low altitude
Bonsai enthusiasts gush over the bantolinau, more so if it is yamadori (collected from the wild). The mature tree has a deeply dark trunk and a gnarly root system; together with the tree’s shiny leaves and yellow/red berries, this appearance makes the bantolinau a favorite among bonsai aficionados.

Kamagong
92
Diospyros blancoi
EBENACEAE • Indigenous • Critically endangered
SIZE: Up to 15m tall; trunk size 40cm diameter TYPE: Evergreen HABITAT: Primary and secondary forests up to 800m altitude
94
Its creamy and sweet, yellow-deep red fruit is called mabolo, also known as the velvet apple or butter-fruit. The mabolo fruit is not popular among Filipinos, but is commonly cultivated in the rest of Southeast Asia. Kamagong wood is used in the Philippines by house builders, carpenters and artisans. Previously, the kamagong was thought to be endemic to our country until the same species was found in Taiwan.
Bolong-eta
Diospyros pilosanthera
93
EBENACEAE • Indigenous • Endangered
SIZE: Up to 20m tall; trunk size 50cm diameter TYPE: Evergreen HABITAT: Found in peat swamp forest
Members of the Ebenaceae family are known to produce ebony wood. While its more famous siblings produce black or brown ebony, the bolong-eta is known among timber traders for its “streaked ebony,” very much in demand for high quality furniture.

Malatinta
Diospyros maritima
EBENACEAE • Indigenous
SIZE: Up to 20m tall; trunk size 50cm diameter TYPE: Evergreen HABITAT: Thickets and forests along the coast and inland
96
The malatinta may have earned its name from the bluish or reddish grey ink-like texture of its freshly-squeezed juice. The fruit is edible and is also known as “sea persimmon” (hence the species name maritima). The non-native persimmon fruit belongs to the Diospyros (“seeds of the gods”) family.
Paguringon
Cratoxylum sumatranum
95
CLUSIACEAE • Indigenous
SIZE: Up to 15m tall; trunk size 20cm diameter TYPE: Evergreen HABITAT: Primary and secondary forests, open woodland, thickets and grassland on well-drained soil
The paguringon may have a rough bark, but when used for treating wounds and scabies, it smoothens out the skin. Also called the kansilay, Silay City in Negros Occidental was named after this tree. In turn, the “Paris of Negros” named the paguringon its official tree.

Bitaog
Calophyllum inophyllum
CLUSIACEAE • Indigenous
SIZE: Up to 20m tall; trunk size 80cm diameter TYPE: Semi-deciduous HABITAT: Sandy, well-drained soil in beaches and coastal thickets
98
“Shade and shelter, food and medicine, sea transport and shore protector; soil improver and ornamental: this is a tree for all seasons and many reasons, for life’s ailments and its enhancements... the Bitaog would seem to make it compete with the coconut tree for the title ‘Tree of Life.’” Ed Maranan, writer, author and journalist; quote from Philippine Native Trees 101: Up Close and Personal
Dangkalan
Calophyllum obliquinervium
97
CLUSIACEAE • Indigenous
SIZE: Up to 30m tall; trunk size 65cm diameter TYPE: Evergreen HABITAT: Secondary and mixed dipterocarp forests on hillsides, to 180m altitude
The dangkalan is a source of the packaging used for the popular edible souvenir from Baguio City with the wacky name sundot kulangot. Dangkalan is becoming a rare tree despite its wide ecological range.

Mangkono
Xanthostemon verdugonianus
MYRTACEAE • Endemic • Endangered
SIZE: up to 25m tall; trunk size 80cm diameter TYPE: Evergreen HABITAT: Very limited habitat mainly Dinagat Island, Surigao, Homonhon Island in Samar, Leyte, Palawan and Sibuyan; usually near seashores in ultramafic soil
100
The mangkono is described as nature’s superstar for its splendid red and white flowers. It is also known as the Philippine “ironwood” for its luxurious timber of extraordinary density. In ten years it grows to a diameter of just 7cm. It grows best in soil where minerals like copper and nickel are present. Mangkono wood sinks in water and is immune from termites.
Mamalis
Pittosporum pentandrum
102-111
PITTOSPORACEAE • Indigenous
SIZE: up to 10m tall; trunk size 10-15cm diameter TYPE: Evergreen HABITAT: Thickets and secondary forest at low and medium altitudes
The mamalis, whose fruit is clustered like orange grapes, is used in the production of wooden beads for ethnic-inspired jewelry. The fruit yields an oil which is used in baths by women after childbirth. Margaret Barwick, in her book Tropical and Subtropical Trees, classified mamalis as endemic to the Philippines, and described the fruit as “bright, waxy and perfect that they look artificial and are pinned on for decoration.”

Toog
112-113
Petersianthus quadrialatus
LECYTHIDACEAE • Endemic • Endangered
SIZE: Exceeds height of 35m tall; trunk size 100cm diameter TYPE: Evergreen HABITAT: Near riverbanks or on hillsides, in swampy and cool places
102
Toog is considered to be the tallest tree in the country; it can grow higher than 40 meters. It is considered a vanishing species, due to the high demand for its wood in the last 20 years, leading to its drastic depletion. Its seeds are edible and, many say, taste like peanuts.
Gakakan
114
Drypetes falcata
PUTRANJIVACEAE • Endemic
SIZE: Up to 5m tall; trunk size 20cm diameter TYPE: Evergreen HABITAT: Batanes Island and Camiguin Island; in secondary forests and wooded thickets at low altitude
Gakakan is endemic only to two island groups in the Philippines: Batanes and Camiguin. Interestingly, Camiguin is tropical while Batanes has a very different sub-tropical climate.
103
Anahaw
Saribus rotundifolius
ARECACEAE/PALMAE • Endemic
SIZE: Up to 20m tall with distinguishing ringed trunk TYPE: Evergreen HABITAT: Luzon, Mindoro, Palawan, Negros, Mindanao; in primary and secondary forests up to 700m altitude
104
The anahaw is a popular ornamental palm planted in parks and gardens. It is the country’s national leaf because of its beautiful design and usefulness. Anahaw leaves are used to make fans and hats. Anahaw is also used for layered thatching and constructing walls of nipa huts. It has decorated the floats and stages of many a barrio fiesta. It is also used to wrap Pinoy “to go” food.
Manila Palm Adonidia merrillii
ARECACEAE/PALMAE • Indigenous
SIZE: Up to 15m high; trunk size 25cm diameter TYPE: Palm HABITAT: North Palawan; in forests on karst limestone
The Manila palm is distinguished by its 2m long arched leaves that are graceful and strong. It is a popular ornamental palm whose light red ripe fruit is a substitute for the (betel nut) of indigenous Filipinos, nganga.
