Stem nearly terete at its base, obtusely angular above. Prickles 
most numerous and shorter near to the base of the stem, straight, 
nearly horizontal ; on the autumnal shoots and the petioles 
hooked. Leaves cuspidate-serrate. Stipules of the flowering 
shoot narrow. “Torus conical. Fruit blue-black.”

Obs. 1. There seems to be no-doubt of this being the plant 
intended by Hayne, although I have not seen the work quoted, 
and as his name is older than that of Weihe I have adopted it. 
None of the figures in the ‘ Rubi Germanici’ exactly represent 
our plants. 
Obs. 2. Some of the forms of this plant, especially var. y, have 
been mistaken for R. corylifolius (Sm.), from which it differs in 
the same respects as the preceding species.

Stems usually slender. Prickles very various in number but 
always slender. Occasionally the terminal leaflet is divided quite 
to its base into three distinct leaflets, the whole thus forming a 
quinate-pinnate leaf, when the plant is the variety pseudo-ideus
