Western Szech’uan: southeast of Tachien-lu, thickets, alt. 3700 | 
m., July 1908 (No. 2139, type; 7; No. 21395; bush 1-3 m.; 9); 
without locality, alt. 3700-4000 m., July 1903 (Veitch Exped. Nos | 
. 4519, 45199; bush 1.2 m.; 9 flowers and fruits). 
This species seems to be nearly related to S. floccosa Burkill, of which I have not 
seen any material. According to Burkill’s description his species differs in having - 
somewhat longer and narrower leaves and slightly hairy ovaries. Both species 
need further investigation. 
The specific name is derived from éyipos, late, and dv6os, flower.
