gigantic even in its variety G6 than the present plant. 
‘The chief points of difference between the latter and spi- 
nosissima are its larger flowers and want of setze among 
the prickles of the branchlets; characters which appear 
to be constant here, although I have not admitted them 
in uniting Sabint and Doniana. However this may be, 
it is too remarkable a plant to escape notice, and if it 
should hereafter be reduced to spinosissima, it must 
stand as a distinct variety. I have little doubt, from 
Bieberstein’s account, that his R. pimpinellifolia is this, 
especially as he divides it from spinosissima, which so 
accurate an observer would scarcely have done unless 
his plants had actually been different.

Stems shrubby, stout, very much branched, six 
inches long, prickly all over. Petioles prickly; leaflets 
in three pairs with an odd one, ovate-oblong, acumi- 
nate, ciliato-serrate, flat, sessile. Flowers pale red, 
small, double; petals ovate-oblong, somewhat acumi- 
nate, flat; peduncles hispid. Tube of the calyx ovate, 
smooth: sepals partly prickly, partly naked. Fruit 
neither large nor pyriform. Lour. 
Known only from Loureiro. It appears to be allied 
‘to the last species, differing in having acuminate leaf- 
lets and prickly sepals. Can it be a congener of R. 
 Lawranceana ?
