SALICACEAE. — SALIX 61

Western Szech’uan: Chiu-ting-shan, thickets, alt. 2300 m., May 
23, 1908 (No. 2124, type; 9). 
Iam very doubtful if this species belongs to the section Longiflorae. In the 
rather large leaves it resembles some forms of sect. Eriostachyae, but the catkins 
are exceedingly small and thin; and I suspect a hybrid origin between a species 
with glabrous and another with hairy ovaries. 
The specific name is derived from dudiBodos, doubtful.
