Western Szech'uan: Ching-chi Hsien, Ta-hsiang-ling, alt. 
2300-3000 m., May 1908 (No. 1429*i*, type; bush 1.5-3 m.; 2). 
.. This species resembles S. dissa Schneider, but differs from it in the somewhat 
Silky under surface of the leaves, the larger and denser aments, the larger anthers, 
the very small dorsal gland and in the slightly larger bracts which are partly 
greenish. S. dyscrita may be of hybrid origin. At first I thought that Wilson's 
No. 2129 (see S. driophila Schneider, p. 59) from the same place might repre- 
sent the 9 plant of S. dyscrita, but the leaves have a denser and different 
pubescence. 
The specific name is derived from dvexperos, ambiguous.
