For each record the following information is given: locality and habitat, Ordnance Survey 10 km. Square, vice-county, finder's initials (see key at end of article) and date of record. The comments are those of the Compilers, based in some cases on information supplied by the Anders. The nomenclature and order of the species are those of Flora Europaea. The Compilers wish to thank the specialists who determined, or confirmed the identity of, specimens. Adiantum capillus-veneris L., Maidenhair Fern. First record for each vice-county. (i) Nayland, United Reformed Church, a well-established colony, TL93, v.c.26, JCW, July 1980. Comm. EM-R. (ii) Ipswich, TM14, v.c.25, two sites near the town centre, the first found bv FWS, and the second by M A H , both in 1977. As a native species this fern is found mainly in the South-west of Britain and in Western Ireland. It is, however, able to establish itself elsewhere as an escape on sheltered walls. Ceterach officinarum DC., Rusty-back Fern. Oulton Broad, on wall of brick shed, TM59, v.c.25, RSB, September 1977. Conf. PGL. PGL states that by March 1981 the colony had increased to 20 plants. He adds that the plant was recorded for Mendham in Hind (1889), and that he himself last saw it on 24/4/69. It was later destroyed during restoration work. Pilularia globulifera L., Pillwort. Dr. E. A. Ellis reports in a letter to FWS dated 12/10/80, "I found an extensive colony of Pilularia still flourishing along the shore of one of the Hopton Ponds (v.c.25), which are part of the Lound Waterworks, at the end of September. I had seen it previously alongside one of the other ponds, but it has gone from that site. It is comforting to know that this rare East Anglian plant has survived in the parish where it was first discovered in 1805! I wish we could say the same for other sensitive species." Azolla filiculoides Lam., Water Fern. Southwold, in dyke, solid growth for about 100 metres, TM47, v.c.25, PGL, 1980. In Suffolk this fern appearssporadically in dykes and ponds in the eastern half of the county. At this site in May 1980 the plants had turned dark red over the whole dyke, possibly as a result of late frosts. Salix nigricans Sm., Dark-leaved Willow. First recorded in Suffolk by EJC at Red Lodge, Freckenham, TL67, v.c.26, 23/5/66. (A specimen was determined by R. D. Meikle in April 1967.) Re-discovered by D R D , 13/9/80, in mixed willow scrub round a shallow pond. Trans. Suffolk
