156 HEREFORDSHIRE RUBl. in a heathy wood, at Edwin Ralph, near Bromyard. Perhaps doubtful between this species and K. Jissus Lindl., to which Rev. "W. Moyle Rogers would refer it. R. suLCATus Vest. Exclude R. sulcatus, Flora, 518. At a single station in a boggy thicket near Staunton-on-Arrow, and only two or three bushes at present in existence. First found, 1891 ; first notice, Jonrn. Bot. 1892, 111. R. PLicATus W. & N. Flora, 84, 518. Heathy or boggy woods and thickets, very local. Great Doward and Howie Hill, in the south of the county ; Colwall, in the east, Lees, Malvern Botany. Var. Bertramii G. Braun. Focke, Syn. Rub. Germ. 117. As the type, and often growing with it ; very local. Cockshot Wood and Howie Hill, in the south; Edwin Ralph, in the east. Fi. Ber- tramii forms a link between Pi. plicahis W. & N. and R. nitidus W. & N. ; approaching the former in habit and in the shape and toothing of the leaflets, and the latter in having stalked basal leaflets and stamens longer than the styles. It will probably prove pretty widely distributed in Britain. First found, 1887. R. AFFiNis AY. & N. Very rare ; at present only known at a single station, in the north of the county. Rough bank at Gorton, near Presteign, June, 1895. First found, 1895. R. iMBRicATUs Hort. Flora, 86. Rare and local ; almost con- fined to the Wye Valley from Sellack parish downward. Sellack ; Foy ; Gannerew. The plant reaches its greatest abundance in the Wye Valley a few miles south of Monmouth, in which district it was discovered by the late Prof. Hort. R. cARPiNiFOLius W. & N. Local and rare, chiefly in boggy thickets. Howie Hill, and other stations in the south of the county ; Lyonshall Park, in the north. Unknown in the east, central, and western parts. R. iNcuRVATus Bab. Flora, 518. Confined to a limited area in the north and north-west of the county, from Ludlow in the north, to Kington in the north-west ; most frequent in the valley of the Lugg, near Aymestry. R. LiNDLEiANUs Lecs. Flora, 85. Widely spread throughout the county; rather abundant in some districts, but apparently much less so in the eastern districts. Hybrids in which R. Lind- leianus is strongly marked occasionally occur. R. ERYTHRiNus Gcuev. Flora, 90, as R. Salteri Bab. Rather local and rare ; absent from a large portion of the county, and nowhere so fine and typical as in neighbouring county of Mon- mouth. Unrecorded for the central, north, or western districts; at St. Weonards and two other stations in the south ; most abun- dant and typical in the eastern districts near Malvern. Its distribution stands thus in striking contrast with that of its nearest ally, R. Lindleianns. First notice, Journ. Bot, 1890, 206. R. RHAMNiFOLius W. & N. (sp. collect.). Var. cardiophyllus Muell. & Lef. Flora, 85. Not very abundant, but distributed over nearly the whole area of the county. A form which is strikingly smaller in all its parts occurs at Belmont, near Hereford, and at two other stations in the county. Other varieties of this bramble
