 RUBUS ADSCITUS AND R. MUTaBILIS. 369

falcate or declining prickles. Calyx green, tomentose, furnished with numerous red glands, aciculi and prickles ; sepals furnished with long folia- ceous points, spreading or retiexed after the flowering. Petals bright pink, very distant, oval, narrow, entire or jagged, gradually narrowed into a broad claw, white, hairy on the outside, glabrous within. Stamens white, much exceeding the yellowish styles, very faintly mottled with pink at the base. Young cai"pels with some very short hairs, soon becoming glabrous, numerous, finally black, shining, slightly juicy. June, middle of July. — On schist and granite. Woods and wooded hills. Maine and Loire : Le Longeron, St.-Leger-du-Bois, Cholet. Vendee: Evrunes, Pouzauges. — Deux-iSevres : Le Temple, Chatiilon, Nueil-sous-les-Aidjiers. — Loire- Inferieure : La Haie-Fouassiure (de I'lsle) ; Nantes.

" Obs. R. vintab'dls is one of the most beautiful and best charac- terized plants of the genus. In the woods of Pouzauges (Vendee) a plant is frequently met with which is distinguishetl from this by having leaves green below, panicle narrower, and pedicels for the most part with but one flower ; however, it appears to be connected with this plant by intermediate forms. It is near the R. pallidus of English botanists, but it is hardly likely to belong to the plant of W. and N."

Having given a translation of Genevier's account of R. mntabiUs, I append to it a description of the Plymouth plant that I have drawn up — " Rnbiis ubliijuuH, Wirtg. ;" Blox. Scemann's Journ. Bot. Vol. VI IL pp. 09, 70 (1870) : — Stem arcuate-prostrate or nearly prostrate, rather stout, angular, furrowed, often purplish and mottled with a white glaucous bloom. Prickles tolerably numerous, not confined to the angles, from long compressed bases, strong, slender, slightly declining or patent, purplish with yellow points, very unequal, passing into aciculi. Aciculi numerous, of different lengths, springing from raised bases. Setae few. Hairs rather scattered. Leaves 5-nate; leaflets rugose, thick, rather convex, above; petiole aciculate, setose, hairy, with many small hooked prickles; termiiuil leaflet with petiole at least one-third of its length, rather broadly ovate, acuminate, points sometimes, not invariably, oblique, slightly cordate at the base, dentate, serrate; side leaflets stalked, ovate- or obovate-acuminate ; basal shoitly stalked, narrowly ovate, pointed. Leaflets with a few scat- tered silky luiirs above, densely pilose beneath, greenish or white felted, veins prominent. Sti|)ules lanceolate, with long silky hairs. Flowering shoots rather still', angular, striate, with numerous prickles, aciculi and long stiff hairs. Prickles of different lengths, declining or slightly hooked, from long narrow compressed bases, sleiuler, sharp. Leaves 3-nate or 5-nate. Leaflets ovate, rather shortly acuminate, terminal one slightly cordate at the base, sometimes with oblique point, serrate, those on the lower part of the stem dentate also, with long scattered silky hairs above, very pilose below, greenish-white or felted. Panicle pyramidal, leafy to near the top, very prickly, aciculate, setose and pilose ; racliis rather rigid, brandies ascending, stiff, three or four lower ones separated and axillary, top dense, rounded. Sepals ovate, with linear, sometimes slightly ical'y points, greenish-white, felted, with small scattered aciculi aiul setic, riv nexed. Petals narrowly ovate, greenish-white, notched and jagged. Filaments white. Styles greenish. Fruit large, symmetrical, glossy black, well flavoured.
