128 WILSON EXPEDITION TO CHINA 
f. aomorensis Seemen: folia late ovata, ad 4 cm. longa et 3.5 cm. lata, breviter 
acuta (iis Populi tremulae similia): Aomori, U. Faurie (No. 808, in part; ex See 
men). To this form may belong C. S. Sargent’s specimen from Mt. Hakkoda, near 
Aomori, from foothills up to 1600 m., Oct. 2, 1892 (shrub 0.6-1.2 m. tall; with 
fruits). 
Salix Reinii, var. cyclophylloides Koidzumi in Tokyo Bot. Mag. XXVII. 91 
(1913). 
JAPAN. Hondo: “Rikuchu, Mt. Iwate and Hayachine-san” (fruiting types, 
ex Koidzumi); prov. Rikuchu, Mt. Iwate, July 15, 1903, S. Arimoto (with fruits; 
may be the same as the type!). 
In this variety the leaves are described as mostly obovate or orbicular, and often 
brownish pubescent on both surfaces when young; the catkins are only 15 mm. 
long. zi 
There are three specimens collected by Faurie in Hondo “ in pago Sambongi," 
May 8, 1908 (No. 6613, c^, No. 6614, 1 m. tall, 9) and “in planitie Sambongi, 
May 1908 (No. 6626, 5-6 m. tall, à?) which are similar to S. Reinii, but I am not 
quite sure whether or not they really belong to this species. The young leaves 
are somewhat blackish, and not paler on the lower surface.

The different specimens referred by me to this hybrid are, of course, not quite 
alike. The type resembles more S. Reinii Franchet & Savatier than S. vulpina An- 
dersson, while others of these forms are nearer to the last named parent. : All show 
a certain mixture of the principal characters of the two parents. According the 
author, S. vulpina, var. discolor Seemen (Salic. Jap. 40 [1903]) may represent
