This very pretty rose was raised by Messrs. James 
Veitch and Sons from seed collected by Mr. E. H. Wilson 
in the Sangpan mountains, near the Tibetan frontier of 
Western China, at elevations of 9500 to 11,000 ft., and the 
plate was prepared from specimens communicated by that 
firm, from plants which flowered at Coombe Wood in May, 
1907. The most nearly allied species, R. Webbiana, is a 
native of the drier regions of the western temperate 
Himalaya. 
Drsoription.—Shrub, densely branched, 5-10 ft. high, 
nearly glabrous, except the stipules. Branches slender, 
red-brown. Prickles in pairs on the flowering branches, 
straight, 3-3 in. long, pale; bristles none. Leaves 
crowded, 4-1; in. long; midrib slender, obscurely 
setulose; stipules small, fringed with glandular hairs.
