CHINA. Chili: Tientsin, near race course (also planted every^'here between 

 Tientsin and Peking), April 18, 1909, E. H. Wilson (c?); Peking, September 16, 



1902, C. S. Sargent (large tree with pendulous branches, " the common Peking 

 Willow" ; sterile); Peking-Nankow road, October 6, 1906, J. G. Jack (" common 

 Willow of Peking plain," large tree; sterile). Kansu: Ranshiu, April 17, 1907, 

 E. Umemura (No. 17, type, ex Koidzumi). 



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: 2 cm.). 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- 

 culture 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 raised 

 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. 



27. Salix hamatidens L6veill6 in Bull. Soc. Bot. France, LVI. 301 (1909). 

 JAPAN. Hokkaido: prov. Ishikari, Sapporo, " secus aquas," June 13, 1908, 



U. Faurie (No. 263, type; 9 )• 



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.
