NORTHEASTERN ASIA. Transbaikalia: Chita, bottom lands of Chita 
River, August 12, 1903, C. S. Sargent (round-headed tree, 10 m. tall, bark very 
deeply furrowed; sterile, doubtful form with broadly ovate stipules as long as the 
petioles). Ussuri: Tien-shan mountains, June 9, 1906, F. N. Meyer (No. 54; 
weeping Willow, rare; with fruits). Amur: south of Harbin, common, August 24, 
1903, C. S. Sargent (large handsome tree; sterile, leaves long-acuminate, up to 
12:2cm.). Korea: Chinnampo, September 20, 1905, J. G. Jack (tree, probably 
introduced; sterile). ; 
Jack sent cuttings to the Arboretum, and these produced a small tree with upright 
branches; and this tree (No. 5737 of the Arboretum, 9 type) bore the 9 flowers 
described above. There are other cultivated c? plants with more pendulous branch- 
lets in the Arboretum, originated from cuttings sent by the Department of Agri- 
eulture under No. 22450 and collected in northern China, prov. Chili, near Paoting 
Fu, probably by F. N. Meyer on January 30, 1908 (No. 250; the ordinary Willow 
which grows excellently everywhere on the dry lands in northern China; needs no 
water supply beyond a scanty summer rainfall). There are also plants rais 
from cuttings sent by W. Purdom (No. 281) from northern China. After having 
described the specimens from Chili as a new species, No. 348 of the Tokyo 
Botanical Magazine has been received with the description of Koidzumi's new 
species which exactly agrees with the plant from Chili. ^ 
This species seems to be the ** Salix babylonica ” of northern China, as mentioned 
by Burkill and others (see S. babylonica, p. 42). S. Matsudana is easily distin- 
guished by its greenish or yellowish twigs, while those of S. babylonica are reddish 
brown or purplish.

The 9 flowers of this species very much resemble those of the true S. fragilis 
Linnaeus. They have a small dorsal gland, a pedicel of about the same length as the 
ventral gland, a short, slightly bifid style and ovate stigmas. The bracts are long 
This curious form looks somewhat like a hybrid between S. eriocarpa Franchet & 
Savatier or related forms and S. amygdalina, var. nipponica Schneider. The 
ovaries are glabrous. It needs further observation.
