SALICACEAE. — SALIX 103 



Mountains, Ft. Schmidt (ex Andersson). Sap;halien: " im Arkaithal," May 27, 

 1891, P. von Glehn (ex Schmidt et fide Wolf); without locahty, 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 i)lant from Saghalien. Neither the cf 

 nor the ? 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 silverj' 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 

 Willows of eastern Asia. Both grow from 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 Maximowiczii 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- 

 dant, 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.
