Eastern Tibet, and Mr. E. H. Wilson, who has also 

 collected this species, remarks that it is common on the 

 mountains of Moupine in Western Szechuan. The bush 

 from which our plate has been prepared was raised from 

 seed sent from the Arnold Arboretum in 1909. At Kew 

 it has grown very freely and borne good crops of its 

 graceful fruit. The seed in question was obtained by 

 Wilson in September, 1908, near Wen-ch'uan Hsien in 

 Western Szechuan at 7,000-10,000 feet above sea-level. 

 In the wild state it occurs in thickets and forms a bush 

 thre3 to five feet in height. At Kew it has proved one 

 of the most easily grown species of Rose, and thrives 

 excellently in stiff "loamy soil. In addition to the highly 

 coloured fruits a marked feature of this Rosa is afforded 

 by the numerous ovate bracts which sometimes exceed 

 in size those shown in our figure. Like other members 

 of its group, R. Davidii should be easily increased by 

 cuttings taken in August and placed in a propagating 

 case in gentle heat.
