HEEEFOEDSHIRE EUBI. 221 and thickets, rare and local. Detected as yet only on the southern borders of the county at several stations in Walford and Hope Mansel parishes, whence it crosses into West Gloucester in the Lea Bailey plantations, Forest of Dean. The plant above-mentioned is named type Koelileri W. & N. on the authority of Dr. Focke, who saw it iyi situ in 1894, and pronounced it without hesitation to be identical with the typical R. KoehJeri of Continental Europe. At the same time it must be observed that our plant is a far more slender, less armed form than any of those which English batolo- gists had been accustomed to name Pi. Koehleri. First found in 1891. Var. b. PALLiDus Bab. Flora, 100. Widely spread in Hereford- shire, as in Britain generally. R. pallidus Bab. (with R. Leyanus Rogers and it. argentatus P. J. Muell. var. clivicola) is one of the species flourishing at the greatest altitude above the sea, rising, in Breconshire at least, to about 1300 ft. Var. c. coGNATUs (N. E. Br.). Flora, 102 (under R. Lejeunei W.) ; 521 (as R. Bloxamii Lees). In woods and thickets, locally abundant. Spread over the south and parts of the central and eastern districts ; most abundant in Haywood Forest and the woods between Aconbury and Ross ; but apparently not occurring to the north of Hereford. The plants brought together here are in my judgment all referrible to a single species ; but I wish to state that I am alone responsible for this arrangement, which I have ventured to make after watching them growing for about twenty years. They have long been subjects of much controversy, and have lately been referred by Dr. Focke partly to R. fusciis, partly to R. Koehleri, and by Rev. W. M. Rogers partly to R. fusciis, partly to R. cognatus. The plants in question are very constant in general aspect, and in the shape of the leaves and of the panicle, but vary greatly in the amount, though not so much in the character of the armature, both of the stem and rachis. They are not precisely identical with the Surrey plant for which the name of Pi. cognatus was first coined by Mr. Brown. First notice, Journ. Bot. 1895, 102. R. Maeshalli Focke & Rogers. In woods and thickets ; not common (at least in a typical state). Plants referred to R. Marshalli by Rev. W. M. Rogers, and representing the species exceedingly well, have been found in Hope Mansel parish in the south, and at more than one station in the north and west. Many other plants, at present omitted as doubtful, will probably come to be ranged under R. Marshalli when its limits are better understood. First notice, Journ. Bot. 1895, 103. R. Fusco-ATEE Wcihc. Flora^ 101. Woods and thickets, very rare. Abundantly at a single station in the south of the county, in plantations and thickets at Welsh Newton. The late Prof. Babington uniformly named this Welsh Newton plant R.fusco-ater W.; and Rev. W. M. Rogers concurs in this identification. First record, Bot. Exch. Club Rep. 1880, 30. R. viRiDis Kalt. In woods ; very rare. Known at present at a single station in the north-west of Herefordshire, at Winfortou. Found also by me in the same year at a single station in Brecon- shire (Glyn Tarell). First found in 1895.
