SOME RECENT SUFFOLK PLANT

RECORDS

For each record the following information is given: locality and habitat, Ordnance Survey 10 km Square, vice-county, finder's name or 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 with very few exceptions those of Flora Europaea. The Compilers wish to thank the specialists who determined or confirmed the identity of specimens. Simpson's Flora of Suffolk is used as the authority for claiming first or second County records, supplemented by the large number of records received since its publication. As in the past two years this list contains a selection of records from the BSBI Monitoring Scheme, 1987-8. Included also are a number of interesting new records from 10 km Square TMOÜ, where one of our members, the Rev. R. Addington, is carrying out a three-year survey on a tetrad basis. Again we have received much information from members of the Society and indirectly from members of the public, who have taken specimens to Ipswich Museum for identification by Martin Sanford. Dryopterispseudomas (Woll.) Holub & Pouzar, Golden-scaled Male Fern. (i) Mildenhall, one clump in ride of forest plantation, TL77, v.c. 26, A L B , 31/5/89. (ii) King's Forest, West Stow, TL87, v.c. 26, FWS, 4/6/89. Several fine specimens in area north of Dale Pond. An uncommon fern in the Breckland. Also there D. filix-mas, Male Fern x D. pseudomas = D. x tavelii Rothm. Polypodium vulgare L. sensu stricto, Polypody. Mildenhall, two patches in mixed Forestry Kommission woodland, TL77, v.c. 26, E M H , 4/6/89. Det R. H. Roberts, Dec. 1989. It is unusual to see Polypody ferns in Breckland woodland, though they are occasionally seen on walls. It is still considered that P. vulgare L. s.s. is much less common in the County than both P. interjectum Shivas and the hybrid between the two species. See Trans. Suffolk Nat. Soc. 20: 76-7. Azolla ftliculoides Lam., Water Fern. 1988 and 1989 were exceptionally good years for this species. Independent records of abundant colonies in Ipswich in the R. Gipping and Handford Cut, TM14, v.c. 25, came from FE, PF and FWS. Also in the R. Stour at Cläre, TL74, v.c. 26, FE, Aug. 1988. Salix repens L., Creeping Willow. (i) Roper's Heath, Tuddenham, in damp hollow, TL77, v.c. 26, FWS, 27/8/89. (ii) B a m h a m Heath, TL88, v.c. 26, GC, 15/6/89. A flourishingcolony in wet hollows.
