 flower-buds). 



NORTHEASTERN ASIA: Mandshuria: south of Harbin, August 29, 1903,

 Transbaicalia: Nertchinsk, 1849, Sentinoff (with fruits); bank of stream near 

 Sryetensk, August 13, 1903, C. S. Sargent (sterile); inmontibus 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 cm. broad and with a coarse dentation, which may belong to U.japojiica 

 Sargent). Amur: "ad. fl. Amur," 1855, R. Maack (No. 103, with very young

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 2.6 m. 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.
