This bramble may be distmguished from the last species, with 
which however it has been often confounded, by the more slender 
stem, which is of a pale colour, either green or purplish green; by 
the gradual transition of the prickles into sete ; by the pale green 
of the leaf, which is less jagged; by the calyx, which is broader 
and shorter than in rudis, has never as in that species the leafy 
point, and is clothed with a whitish tomentum instead of the dark 
setee; there are however on the calyx a few scattered glands. 
Other points of difference are, that the panicle is less branched, 
leafy only below, except in 6, with ternate leaves. Rachis sparingly 
prickly and not setose; the peduncles however are glandulose. 
The petals are large and of a bright rose-colour. The first form 
is the R. Radula of the author of the species. It is that of ex- 
posed situations, and has the characters of the species best de- 
veloped. It is the most glandulose, and has the beautiful chan- 
neling of the leaves in the course of the ramifications best 
marked,—a character pointed out to me by my friend Mr. Ba- 
bington. 
The var. 8. Hystriz is the form of shaded woods, and is the 
most common. ‘The glands are much fewer, and the leaves less 
grooved and less pale beneath. 
The var. y. pygmeus is altogether a more feeble plant. 
The var. 6. foliosus, which was first brought under my notice
