 160 HEREFORDSHIRE RUBI. pedicels, and calyx with rather numerous, slender, unequal, stalked glands, far exceeding the grey felt and short hair. Petals white ; stamens white; styles short, green. Sepals ovate -acuminate, spreading, externally green, with white margins ; points rising round the fruit, which is globular and acid. Locality. — Woods on the Beacon Hill near Trelleck, Monmouthshire, abundantly. This bramble was named by Dr. Focke, from dried specimens, R. myrica Focke, var. virescens G. Braun, and was sent out as such in Set of British Rubi, 1892-1895 (No. 60) ; in 1894, however, on seeing the plant growing, Dr. Focke withdrew the name. Dis- tinctive features are the curiously suberect habit and sepals recalling the Suberect group, in conjunction with a glandular panicle; and tbe gradually acuminate leaflets, green on both sides. The plant above described occupies a large area of woodland (some three square miles) on Beacon Hill, Monmouthshire. On the adjoining heath occurs what seems to be a form of the same bramble with leaves much more deeply cut and plicate, and with the glands of the panicle-rachis fewer and subsessile. A hybrid also occurs on the heath between the last-named plant and (probably) R. S-prengelii W. R. MicANS Gren. & Godr. Flora, 91, 519 (as R. adscitus Genev.). Widely distributed, but not very common. In thickets and open ground, not in hedges. Sellack and other localities in the south ; Lyonshall in the north of the county ; unrecorded from the eastern and central districts. E. HiRTiFOLius Muell. & Wirtg. Flora, 92 (under 7?. adscitus Genev.). In woods and thickets, rare and local. At a single station in the south (Hope Mausel), and a single station in the north of the county (Ludlow). Very abundant at its northern station over several miles of woodland and rough open ground, and extending into Shropshire. In the southern station the main colony of the plant is in West Gloucester, where it abounds in heathy plantations on Mitcheldean Meend. The Herefordshire plant was determined as R. hirtifolius Muell. & Wirtg. by Dr. Focke in 1892, but it was not until the totally different plant of the Plymouth neighbourhood was found not to be Mueller & Wirtgen's bramble that it was open for us to accept Dr. Focke's determination with regard to the Here- fordshire bramble. First record, Journ. Bot. 1895, 80. R. PYRAMiDALis Kalt. Flo7'a, 91 (as R. villicaulis W. & N.). Abundant throughout Herefordshire as a woodland plant. The Herefordshire plant is not typical R. pyramidalis Kalt., which hardly occurs in the county, but a variety with longer panicle, larger leaflets, and a freer growth than usual. Var. EGLANDULosA. The variety here in view is a handsome plant, strikingly different in aspect from ordinary Herefordshire R. pyramidalis, and equally so from the type. In abundance in Cowleigh Park, Malvern, in the east, and Shirl Wood, Eardisland, in the north of the county. R. LEUcosTACHYs Schlcich. Flora, 88. Very abundant almost throughout Herefordshire, and varying extremely ; the most remark- able- varietal forms being (1) those in which the stem and rachis bear numerous acicles and stalked glands ; (2) another in which the
