Obs. The differences between the R. sylvaticus and R. villi- 

 caulis of the ' Rubi Germ.^ do not seem to be more than those of 

 varieties. The under side of the leaves of the latter is usually 

 rather paler, but in all respects the characters between them are 

 only those of degree. I take R. sylvaticm as the specific name 

 from its standing first in that work, and also because villicaulis 

 has been often misapplied in this country to R. leucostachys /9.

Stems mostly quite prostrate, very prickly ; pubescence of pa- 

 tent hairs. Prickles not confined to the angles of the stem. Leaf- 

 lets of the same colour on both sides. Flowering shoot and pa-

 Sepals linear-lanceolate.

R. Sprengelii, Ruh. Germ. 32. 10. 



A low trailing plant with greenish purple stems, which are 

 very slender and either simple or branched. Prickles pui'ple, 

 yellow-tipped, small and slender, and so extremely uncinate that 

 the point is parallel with the stem. Hairs rigid, shining and pa- 

 tent, but not sufficiently numerous to produce the appearance of 

 pubescence. Leaves rarely otherwise than ternate. Petioles 

 armed as the stem, furrowed above. Leaflets obovate acuminate, 

 irregularly but finely and acutely serrated, bright shining green 

 above, with a few spreading hairs and the principal venations 

 grooved, green and hairy beneath with very prominent veins, and 

 the midrib armed with a few slender uncinate prickles. Ter- 

 minal leaflet with its petiole geniculated, lateral leaflets broader 

 externally and somewhat lobed. Stipules with small glands. 

 Panicle — or rather flowering stem, as it grows erect from the last
