Stems short, erect, branched ; prickles scattered, unequal, straight, slender, 
subulate. Leaflets 5-7, obovate, fin. long, glabrous with a few large glands on the 
upper surface, glandular and subglabrous beneath, doubly serrated ; petioles 
glandular and aciculate, subglabrous ; stipules adnate, gland-ciliated, with deltoid, 
free tips. Flowers solitary ; peduncles hispid. Calyx-tube globose, densely 
prickly ; lobes ovate, simple, with a long point, i in. long, glandular on the back 
and edge. Petals pink, not longer than the sepals. Styles free, glabrous. 
Fruit small, globose, very prickly, crowned by the subpersistent sepals. 
Rosa asperrima is nearly related to Rosa ghitinosa Sibth. & Sm., 
from which it differs in its straight, slender main prickles, larger, 
less glutinous leaflets, intensely prickly calyx-tube, simple sepals, and 
glabrous styles. The variety interjecta of Burnat & Gremli 1 differs 
from the type by its smaller leaflets and hairy styles. The species 
inhabits the mountains of Persia at elevations of from 6,000 to 9,000 
feet above sea-level. It has not yet been cultivated in Kngland.
