R. pulverulenta Bieb. ass cauc. 1.399. Poir. suppl. 
enc. in lL. 
Hab. in collibus circa acidulam Narzana Caucasi sub- 
alpini, (Bieb.) (v. v. c. fl. delaps.) 
A low stiff shrub. Prickles straightish, strong, 
those of the ramuli intermixed with numerous sho 
tender setz, tipped with a grey gland. Leaves rather 
hairy: stipule narrow, spreading, glandular, somewhat 
undulated; petiole prickly, glandular; leaflets 5-7, 
oval, pointed, doubly serrated, frosted all over with 
grey glands, their odour oily unlike that of R. rubigi- 
nosa, (sui generis). Flowers solitary, pale red, almost 
sessile, involucrated by about four approximated, ho- 
rizontally spreading, reduced leaves, rarely having 
bracteze ; peduncles slightly pubescent ; tube of the calyx 
roundish, naked; sepals spreading, foliaceous, with 
very numerous equal narrow segments; disk almost 
obliterated and mouth wide; styles very villous. Fruit 
ovate, smooth, bright red, crowned with the narrowed, 
connivent, glandular sepals, its peduncle with no hairs. 
Lyell’s MSS. 
A very curious plant, for which Iam obliged to 
Mr. Lyell. It was imported by Loddiges under the 
name of R. precox. 
From R. rubiginosa it is very distinct, as indeed it 
is Poti every thing else. The approximated floral 
leaves, grey with glands on their upper surface, and 
its dwarf, stunted habit distinguish it without difficulty. 
Native of the subalpine hills of Caucasus, where it 
was gathered by Bieberstein.
