A little stunted shrub with almost simple erect 
shoots; which are brownish and defended by dense, 
slender, unequal, straight prickles and sete. Leaves 
chiefly about the ends of the shoots, without pubes- 
cence ; stipules narrow, glandular at the back ; petioles 
glandular and setigerous, now and then furnished with 
a few little straight prickles; leaflets 5-7, elliptical or 
orbicular, doubly serrated, beneath rusty with glands. 
Flowers solitary, cup-shaped, ‘small, among the leaves, 
without bractez; peduncle and calyx densely clothed 
with glands and setz, except the upper part of the 
globose tube; sepals reflexed after flowering, longer 
than the unripe fruit; disk a little elevated: the pro- 
truding ends of the styles and stigmas not very hairy. 
This little plant has hitherto been found only in the 
south of France, unless the synonym quoted from Pal- 
las belongs to it. However, his account is too incom- 
plete to enable us to determine it satisfactorily ; and 
the very different habitats of the two will probably be 
considered a material objection. It resembles in many 
respects R. spinosissima in a stunted state. The glands 
on its leaves appear sufficient to prevent their being 
mistaken for each other 
R. provincialis of Bieberstein answers precisely to 
this, and confirms me in supposing that the synonym of 
Pallas belongs to it.
