176 WILSON EXPEDITION TO CHINA 
daisenensis Seemen, although the latter, according to von Seemen’s figure, has 
longer catkins which are more distinctly pedunculate; the leaves are rather coarsely 
denticulate, and the bracts and stigmas seem to be different. 
The specific name is derived from du¢nptoros, doubtful.

CHINA. Without locality or date, W. Purdom (fruiting type). ; 
With its long fruiting aments and its entire oblanceolate leaves this species 
looks distinct, but somewhat resembles forms of S. opaca Andersson (see p. 159). 
The Willows of northern China are still very badly known and need further study. 
The specific name is derived from péAeos, useless.

1913, E. E. Maire (type, 2). 
I have received a part of a branchlet of this interesting Willow from Mgr. Lé- 
veillé in honor of whom I have named this species. Not having seen the leaves 
and < flowers, I cannot refer it to a section, but it is certainly different from all 
the numerous Willows I have seen from China and the other parts of our area.
