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. Chara hispida L., Hispid Chara. Hopton Fen, TL97, v.c. 26, FWS, 1981. Det. Mrs. J. A. Moore. A local species of fen pools and calcareous ditches. Azollafiliculoides Lam., Water Fern. Barrow, TL76, v.c. 26, GDH, 1/10/81. First record for West Suffolk. Dr. Heathcote commented that the species covered one of the ponds which the ducks did not use, but was entirely absent in a much-used pond only about 100 yards away on the same roadside. Suaeda vera J. F. Gmelin in L., Shrubby Seablite. Martlesham Creek, Woodbridge, one large plant, TM24, v.c. 25, IMV, 5/6/81. A fairly frequent species on the coasts of Essex and Norfolk, but very rare in Suffolk. This species was first recorded from Martlesham by R. Burn in the 1930s and subsequently by L. W. Howard in the 1950s. Montia sibirica (L.) Howell, Pink Purslane. Westleton, TM46, v.c. 25, ATP, 1981. Det. Mrs. J. Westcott, 1981. A rare plant of shady places on acid soils. The only recent Suffolk record. At this site, the species covered an area of approximately 4' by 4' in a thicket adjacent to the garden of Dr. and Mrs. Pagan. Ranunculus parviflorus L., Small-flowered Buttercup. Landguard Common, TM23, v.c. 25, AC, 20/4/81. Hb. E & MH. The only recent record. It is interesting to note that this species is also recorded in Hind's Flora from Landguard Fort. Myosurus minimus L., Mousetail. Martlesham, one plant at edge of barley field bordering river, TM24, v.c. 25, IMV, 12/5/81. A very rare weed of arable fields. Barbarea intermedia Boreau, Intermediate Yellow Rocket. Ipswich, several small plants on Riverside Walk, near Sarsen Stones, TM14, v.c. 25, FWS, 18/5/81. Det. EJC, 6/81. Hb. E & MH. As the name implies, this species is intermediate between B. vulgaris, Common Wintercress, and B. verna, American Land-cress. In Suffolk, a rare or overlooked casual. Trans. Suffolk Nat.

Palgrave, by the River Waveney, smali vigorous colony, TM17, v.c. 25, FWS, 25/8/80. Unlikely to persist as Vegetation is constantly removed from the river by the authorities.
