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 tiie 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. —

" 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 —

 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.
