hairy); Nankow, October 6, 1905, J. G. Jack (with mature leaves and 
flower-buds). 
NORTHEASTERN ASIA: Mandshuria: south of Harbin, August 29, 1903, 
C. S. Sargent (sterile, leaves up to 8.5 cm. long and 3.8 em. broad); on plain east 
of the Khingan mountains, very common, September 15, 1903, C. S. Sargent 
(tree 10-13 m. tall, pale bark, round head of pendulous branches; sterile). 
Transbaicalia: Nertchinsk, 1849, Sentinoff (with fruits); bank of stream near 
Sryetensk, August 13, 1903, C. S. Sargent (sterile); in montibus transbaicalensibus, 
1829, N. Turczaninow (with young fruits; there is on the sheet in Herb. Gray 
a branch with mature leaves which are very rough, roundish-ovate, up to 7 cm. 
long and 5 em. broad and with a coarse dentation, which may belong to U. japonica 
Sargent). -Amur: “ad. fl. Amur,” 1855, R. Maack (No. 103, with very young 
fruits and leaves). 
I have not seen a specimen from Korea, where it was found by Komarov and 
Nakai. U. pumila is not recorded from Japan nor from the Altai, but it is apparently 
common in Turkestan, where it is represented by the very closely related var. 
Arborea Litwinow (see p. 262). Some of the specimens enumerated above may be- 
long to U. glaucescens Franchet (see p. 263), which seems to be a very similar 
Species. 
Ulmus pumila is common in the form of a bush or low bushy tree on the Lushan 
mountains in Kiangsi, but I never met with it in Hupeh and only with two or three 
doubtfully wild trees in Szech’uan. It does not grow in Japan, but is common 
in Mandshuria and Transbaical. In northern China it is widely distributed, hav- 
ing been reported from the shores of the gulf of Chili westward to Chinese Turkestan. 
In and around Peking this Elm is abundant, and in the park surrounding the Temple 
of Heaven many fine old trees may be seen. It is a rather low tree, growing from 10 
to 16 m. tall, with a short trunk from 1.3 to 2.6m. in girth; the bark is rough and 
deeply corrugated, and the branches are spreading and ascending-spreading and 
form a bushy crown. Under cultivation in this Arboretum it grows rapidly and 
makes a neat and shapely tree. E. H. W.
