 1906, 157. — Willmott, Gen. Rosa, I. 209 (1911). 



Rosa reducta Baker in Willmott, Gen. Rosa, II. 489, fig. 158 (1914). 



Western Szech'uan: south of Sungpan Ting, valley of Min 

 River, alt. 2300-2600 m., August and September 1910 (Nos. 4642, 

 4026; bush 1-2 m., flowers pink, fruit orange-red) ; Wen-ch'uan Hsien, 

 valley of Min River, alt. 1600-2000 m., September 1908 (No. 1053, 

 Seed No. 1055; bush 2 m. tall, fruit orange-red); west and near 

 Wen-ch'uan Hsien, alt. 2600-3000 m., October 1910 (No. 4197; bush 

 2-3 m. tall, fruit orange-red); without locality, May 1904 (Veitch 

 Exped. No. 3542"^; bush 2 m. tall, flowers pink). 



This Rose is very common in the valley of the Min River from Wen-ch'uan 

 Hsien to Sungpan Ting, but is rare elsewhere. The typical form with its paniculate 

 corymbs and crowded bracts is very distinct, but depauperate forms with the 

 inflorescence reduced to a solitary flower are difficult to distinguish from R. 

 Wilhnoltiae Hemsley; the calyx and fruit, however, are always stipitately glan- 

 dular, the calyx is persistent, and the styles are more or less exserted. Baker 

 founded his R. reducta on plants raised from our No. 1053, which is one of these 

 depauperate forms. Solitary to many-flowered inflorescences can be found on the 

 same plant, and their size appears to depend largely upon the vigor of the branch.

Western Hupeh: Fang Hsien, thickets, alt. 1600-2300 m., June 

 1910 (No. 4644, type); same locality, July 1901 (Veitch Exped. No. 

 2325^). 



This is a shrub from 1.5-2 m. tall with small rosy-pink flowers and is distinguished 

 from the type by its leaflets, which are glabrous except for a few straight appressed 

 hairs on the lower surface of the midrib.
