This is a very common species in the mountain thickets of extreme western Sze- 

 ch'uan between 2000 and 4000 m. altitude. The flowers vary considerably in color, 

 and the pedicels and calyx-tube are smooth or densely stipitate-glandular. The 

 typical form, which has dark red flowers, is abundant in the upland thickets round 

 Tachien-lu and is one of the most beautiful of Roses. This species is closely related 

 to a Rose found in the Sikkim Himalaya at 3300 m. alt. and which w^e think may 

 be R. Hoffmeisleri Klotzsch. However, until the flora of the regions between 

 western Szech'uan and Sikkim is known it appears to us best to consider 

 them distinct species. M. de Vilmorin's Rosa macrophylla, var. ruhrostaminea 

 (in Jour. Hort. Soc. Land. XXVII. 490, fig. 139 [1902-03]) is doubtless referable to 

 one of the numerous color forms of Rosa Moyesii, or to the following variety.
