Floret Junio. (Bieb.) 
Two or three feet high, much branched. Prickles 
very strong, much dilated at the base, hooked, and 
scattered. Stipules acute, glandular on the outside ; 
petioles prickly and glandular; leaflets 7, ovate-lanceo- 
late, acute, finely and doubly serrated, smooth above, 
hairy beneath. Flowers numerous, the size of R. ca- 
nina; peduncles, tube of the calyx, and sepals ve 
rough with glands; the latter with a linear-lanceolate, 
serrated point, longer than themselves, at the base pin- 
natifid; petals white; styles hairy, much shorter than 
the stamens. Fruit globose, hispid, dark purple? 
(atrocerulei.) Bieberstein. 
This is known only from the above description of 
Bieberstein. I have little hesitation in referring it to 
this division, on account of the glands on the stipule 
and petiole. A similar tendency to produce the re- 
markable sepals from which it has been named, is evi- 
dent in R. pulverulenta.
