532 WILSON EXPEDITION TO CHINA 
This is a very common species above 2000 m. alt. in north-west Hupeh, and is 
easily recognized by its villose pedicels and ovary, rather short, elliptic leaves with 
the midrib floccosely tomentose on the under side.

Western Szech’uan: west and near Wén-ch'uan Hsien, wood- 
lands, alt. 3300 m., October 1910 (No. 4235, type); near Sungpan 
Ting, woodlands, alt. 3500 m., October 1910 (No. 4250). 
This species seems most closely allied to R. rufum Batalin which we have not seen 
but according to the description this plant has shorter and broader leaves, 
rounded at the ends, longer petioles, a longer corolla-tube and shorter stamens, 
reaching only to the base of the lobes. 4 
This species is named for General Stephen Minot Weld, a former president of 
the Massachusetts Horticultural Society and a generous supporter of Wilson's 
expeditions to China.
