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.
