Stems short, erect, much branched ; prickles very dense, slender, spreading, 
unequal. Leaflets 7-9, obovate, obtuse, in. long, rigid, doubly serrated, green, 
glabrous on the upper surface, glandular and slightly pubescent beneath, glandular 
on the margin ; petioles pubescent, glandular and aciculate ; stipules adnate, with 
small glandular free tips. Flowers solitary ; peduncles short, densely hispid. Calyx- 
tube globose, naked or hispid ; lobes simple, i in. long, glandular on the margin. 
Petals small, white or tinged with red. Styles free, villous. Fruit globose, brown, 
naked or hispid ; sepals spreading, persistent. 
The Rose of a Thoiisand Thorns is a curious and interesting variety 
of Rosa spinosissinia L. It differs from the type in the glands which 
occur on the back of the leaves, on the petioles and on the margin 
of the sepals, in its densely hispid pedicels and in its doubly toothed 
leaves. 
It is connected with Rosa spinosissinia by Rosa Ripartii of 
Deseglise. It has, however, no connection with Rosa villosa L,, to 
which it was referred by Lapeyrouse.^ It inhabits Spain and also 
the south of France, where it is found growing in the stony, arid 
parts of the Route de Mireval, near Montpellier. De Candolle, who 
describes it in his Flore Francaise, gives Dauphine and the neighbour- 
hood of Lyons among the localities where it occurs ; but there does
