R. germinibus depresso-globosis pedunculisque glabris, 
floribus subgeminatis, foliis oblongis acutis, petiolis 
venisque subtus pubescentibus, aculeis caulinis ge-

Aculei breves uncinati geminati infra axillares, non’

This is adopted by Pursh without addition or any 
further remark, than that it is a low shrub with a large 
flower, growing on dry sunny hills from New England 
to Carolina. , 
R. gemella may bea distinct species, but by the 
preceding account can be distinguished from R. carolina 
only by the smooth fruit. 
The native country of the Linnzan specimens de- 
scribed by Sir James Smith in Rees’s Cyclopedia is 
unknown. They are very incomplete; but as far as 
any opinion can be formed of them, are European and 
probably of R. cinnamomea, the leaflets being only a 
little broader than usual. Certainly they answer in no. 
way to Willdenow’s description, “‘ Media inter lucidam 
et carolinam.”
