Western Hupeh: Fang Hsien, alt. 2300-2600 m., May 16, 1909 
(No. 2116, type; 9; bush 2.4-3.6 m., much branched); same place, 
side of streams, alt. 1700-2300 m., May 16, 1909 (No. 2116°'*; bush 
1.8-2.4 m.; 9 flowers a little older). 
This species comes from the same place as S. rhoophila Schneider, but it differs 
from that species in the distinct styles and the silky bracts. No. 21106bis looks 
somewhat intermediate with its glabrous bracts and distinct styles. 1 do not 
know if No. 2116*is really belongs to S. polyclona, but it differs also from S. rhoo- 
phila Schneider. Both these species may be distinguished from the forms of S. 
longiflora Andersson or S. cathayana Diels by their leafless or shorter peduncles 
and by their different geographical distribution. It is extremely difficult to inter- 
pret the Chinese Willows of this section, and I think it better to separate at present 
the different forms rather than to unite them without sufficient reason. AS 
I have stated above, central China has an uncommonly rich development of the 
genus Saliz, and anybody who has been earnestly interested in the study of this 
genus knows the difficulty in obtaining sufficient material of the flowers of the two 
sexes and of mature leaves of both. Mr. Wilson, however, has been more success- 
ful in securing complete material than other collectors of Chinese Willows. 
The specific name is derived from soAoxAevos, with many branches.
