Mountains, Fr. Schmidt (ex Andersson). Saghalien: “im Arkaithal," May 27, 
1891, P. von Glehn (ex Schmidt et fide Wolf); without locality, Fr. Schmidt (in 
Herb. Gray). 
This is a very interesting species with rather small and slender catkins and narrow 
leaves which are nearly entire in Schmidt’s plant from Saghalien. Neither the c 
nor the 9 flowers of this specimen have any glands. Further information is given 
in the key, pp. 75 and 85.

, This is a striking Willow with its large leaves bluish white beneath, its long cat- 
kins and its silvery fruits. Sterile branchlets often resemble those of S. Caprea 
Linnaeus, but the adult leaves of S. Urbaniana are nearly or quite glabrous, their 
serration is rather regular, the petioles are comparatively longer, the stipules are 
more obtuse and the buds are acute and compressed, not obtuse and thick as in 
S. Caprea. For further remarks see S. cardiophylla Trautvetter & Meyer. 
This and the closely allied S. cardiophylla grow to a greater size than any other 
illows of eastern peo Both grow boi 20 to 25 m. tall and have a thick trunk 
from 6 to 8 m. in girth with deeply fissured bark and massive spreading branches, 
and in general appearance suggest Populus Mazimowiczii Henry. S. Urbaniana is 
common on the shores of Lake Chuzenji, especially at the western end. Elsewhere 
in Japan from Mt. Ontake in Shinano province in central Hondo and northward 
I found it growing sparingly in mountain valleys. In Hokkaido it is more abun- 
t, and some fine specimens are growing in the park in the city of Sapporo. 
Pictures of this Willow will be found under Nos. x303, x372, x373 of the col- 
lection of my Japanese photographs. E. H. W.
