An erect, much-branched shrub, 3-4 feet high ; prickles crowded, slender, 
straight, very unequal. Leaflets 3-5, obovate, very small (j-$ in. long), obtuse, 
deeply incised, slightly pubescent on the upper surface, densely pubescent with 
raised veins beneath ; petioles pubescent and aciculate, not glandular ; stipules 
adnate, with ovate free tips. Flowers solitary ; peduncles very short, naked. 
Calyx-tube globose, hispid ; lobes ovate-lanceolate, acuminate, in. long, pubescent 
on the back, the outer compound. Petals bright red, not longer than the sepals. 
Styles free, villous, not protruded. Fruit globose, very hispid, i in. diam., crowned 
with the erect subpersi stent sepals. 
Rosa viimitifolia is a native of Lower California ; and was dis- 
covered in April 1882 by Dr. C. C. Parry and Mr. C. G. Pringle, 
near the 32nd parallel of north latitude. It most resembles the low 
coast-sandhill forms of Rosa sfiinosissima L. both in habit and armature, 
but differs in its much fewer, very small, deeply incised, pubescent 
leaflets and densely hispid fruit. It was planted out at Kew but did 
not survive, and is probably not hardy in England.
