Plantae Wilsonianae 2: 328 (1916)

Rosa multibracteata Hemsley & Wilson in Kew Bull. Misc. Inform. 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. 3542a; 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. Willmottiae Hemsley; the calyx and fruit, however, are always stipitately glandular, 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.

With rose-pink flowers there is the pretty R. Willmottiae which is an erect-growing shrub with arching branches, small gray-green leaves and flowers in pairs or singly, and the allied R. multibracteata with larger and greener leaves and clusters of numerous rose-colored flowers.
