grows to a height of 3 meters, has rose-red flowers, coral-red fruits, 

 and more or less reddish purple shoots and branches remarkably free 

 from prickles. (Adapted from Sargent, Plantae Wilsonianae, vol. ^, 

 p. 322, 1915.) 



42975. Rosa bella Rehd. aud Wils. 



This pretty rose from the mountains in northwestern Shansi 

 seems most closely related to Rosa moyesii Hemsley and Wilson, 

 which is a much more vigorous plant with stout prickles, larger 

 usually more acute leaflets pubescent beneath, at least on the mid- 

 rib, globose ovoid flower buds abruptly contracted at the apex, 

 larger flowers, and pinnate sepals. It may also be compared with 

 R. sweginzowii Koehne, which differs chiefly in its stouter, much- 

 flattened prickles, the usually double serrate leaflets more or less 

 pubescent beneath, in the globose-ovoid flower buds, and in the pin- 

 nate sepals. (Adapted from Sargent, Plantae Wilsonianae, vol. 2, 

 p. 3^2, 1915.) 



42976. Rosa caudata Baker. 



'• This is a rose discovered by Wilson in western China. It is one 

 of the Cinnamomw section of the genus, and is a tall vigorous shrub 

 with stout arching stems covered not very thickly with stout spines, 

 dark-green foliage, and flowers about 2 inches in diameter, in wide, 

 sometimes 25-flowered clusters. The beauty of the flowers is in- 

 creased by the white markings at the base of the pure pink petals. 

 The fruit is orange-red, an inch long, gradually contracted above 

 into a narrow neck crowned by the much-enlarged calyx lobes. 

 This handsome rose is flowering now for the third year in Ihe 

 arboretum; it is perfectly hardy and an excellent addition to the 

 roses of its class." (Arnold Arboretum Bulb tin of Popular Infor- 

 mation, new ser., vol. 1, p. -}£.) 



42977. Rosa corymbuxosa Rolfe. 



"A distinct new species with unarmed or sparingly prickly 

 branches and numerous small flowers in corymblike inflorescences. 

 Flowers three-fourths to 1 inch across. Petals broadly obcordate, 

 deep rose above, white at the base. Fruits globose, glandular, 

 about one-third of an inch long, crowned by the persistent sepals. 

 Central China." (Kew Bulletin of Miscellaneous Information, New 

 Garden Plants of the Year 1915. p. 80.) 



42978. Rosa davidi Crep. 



An orange-fruited, pink-flowered rose from western Szechwan, 

 China, reaching a height of 5 meters at altitudes of 1,600 to 3,000 

 meters. It is the species nearest, in China, to Rosa macrophylla 

 LindIey"of the western Himalayas. (Adapted from Sargent, Plantae 

 Wilsonianae, vol. 2, p. 322, 1915.) 



42979. Rosa helenae Rend, and Wils. 



"From the seeds of a rose collected by Wilson in western China; 

 a new species of the Moschata group has been raised. It is now 

 flowering in the arboretum for the third year, and is a vigorous 

 and perfectly hardy shrub. ■" or 6 feel tall, with slender, arching
