leaves and hispid fruit distinguish it, from the latter its 
equal small prickles and black fruit. The figure indi-

possession of Mr. Lambert are specimens of a Rose 
from Davuria marked R. davurica ; but probably by

distinct species, they must be referred to this, from 
which they chiefly differ in the colour of their fruit, 
which is not black, but red and smooth, in an unripe 
State.
