128 ROSA SETIGERA. 
The above account of Dr. Roxburgh is the only au- 
thority for the present species. From the little that is 
said of it I should almost doubt its being different from 
R. sintca, but I have met with no instance of that 
species producing more leaflets than three; this is said 
to have from 5 to 9. It should also seem to be more 
robust. 
73. ROSA setigera. 
R. sepalis pinnatifido-setigeris, stylis coalitis, fructibus 
muricatis.

Ach. Richards MSS. 
For the foregoing account of this very little known 
species, 1 am much indebted to M. Achille Richard, 
who has taken the trouble to examine the herbarium 
of Michaux for the purpose. Its united styles distin- 
guish it from the rest of this division.
