SOME RECENT SUFFOLK PLANT RECORDS

c o m p i l e d b y E . M. HYDEandF. W. SIMPSON For each record the following information is given: locality and habitat, Ordnance Survey 10km 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 and second County records. Dryopteris pseudomas (Woll.) Holub and Pouzar, Golden-Scaled Male Fern. Levington, colony of eighteen specimens near the Decoy, associated with D. filix-mas (L.) Schott and the hybrid D. filix-mas x D. pseudomas. Also D. carthusiana (Vill.) H. P. Fuchs, Narrow Buckler Fern, and D. dilatata (Hoffm.) A. Gray, Broad Buckler Fern, both fairly abundant. TM24, v.c. 25, FWS, 19/5/85. Polypodium x mantoniae Rothm., a hybrid Polypody. (P. interjectum Shivas x P. vulgare L.) Ipswich, on brick wall in Belstead Road, TM14, v.c. 25, MNS, 17/11/85. Det. R. H. Roberts. One of only a handful of Suffolk records. It requires expert determination. Azolla filiculoides Lam., Water Fern. Felixstowe, in ditch near Peewit Caravan Park, TM23, v.c. 25, EMH, 27/7/85. It completely covered one section of the ditch. Salix fragilis L. var. russelliana (Sm.) Koch, Bedford Willow. Barham, flooded gravel pits, TM15, v.c. 25, PGL, 25/8/85. This is the only recent record of this member of the native S. fragilis L. agg., Crack Willow. First described by J. E. Smith as S. russelliana Sm. and recorded in Hind's Flora for four West Suffolk sites. It is stated as being the most widespread member of the Salix fragilis complex (Meikle, 1984). However, all true Bedford Willows are female trees; the male tree is unknown. If supposedly male trees are found, they are likely to be hybrids, or var. fragilis. Salix x rubens Schrank, White x Crack Willow. (iS. alba L. x S. fragilis L.) Barham Pits, TM15, v.c. 25, PGL, 25/8/85. The first substantiated Suffolk record for this hybrid. It was found in an extensive area of flooded gravel pits, where there are many Salix species, varieties and hybrids. A very variable hybrid with a wide ränge of intermediate forms. Salix triandra L., Almond Willow. (i) Hitcham, marshy ground by stream, TL95, v.c. 26, PJW and EM-R, 2/7/86.
