There is no species of Rosa in which my endeavours have been 
more unsuccessful than in this. Iam neither satisfied in what I 
have joined together, nor in the marks by which I have attempted 
to discriminate it from other species. The variety « is adopted 
merely from Jacquin; and, as far as is at present known, is not à 
British plant. I have therefore drawn up my description from the 
variety B: an examination of the specimens of `R. collina possessed 
by Sir J. E. Smith, and of those in the Herbarium of Sir Joseph 
Banks, and a comparison of these with the figure in the Flora Au- 
striaca, enable me to state that this x variety differs only : from. L in 
the want of hairs or giands on the peduncle. | Tn this state it ap- 
proaches very nearly to R. bractescens, being scarcely distinguish- 
able, except by the somewhat smaller bractéæ and the entire 
nakedness of the upper surface of the leaf; and as tbat species 
has frequently a glandular, or rather a weakly setose peduncle, 
exactly like that of Jacquin's figure, I have doubted whether 
T ought not rather to have attributed the name and synonym to 
that plant. Jacquin, however, could hardly have passed unno- 
ticed the remarkably enlarged bractescent stipulæ accompanying 
the inflorescence of R. bractescens ; he describes the prickles as 
* validi," although in the figure they are represented as much 
weaker. than is the case with most Roses of this subdivision of 
the genus, and the folioles as ** atro-virentia," whereas they are 
figured pale and. glaucous ; both figure and description attri- 
bute a dark cartilagineous summit to "e serratures. These cir- 
cumstances
