spreading head and a relatively thick trunk. The flowers are sometimes used as 

 a yellow dye in the same way as those of Sophora japonica Linnaeus. Colloquially 

 both trees are spoken of as the " Huai shu." Pictures of this Koelreuteria will be 

 found under Nos. 151 and 261 of the collection of Wilson's photographs and also 

 in his Vegetation of Western China, Nos. 277 and 278. 



Here may be added a note on another Chinese species not collected during the 

 Arnold Arboretum Expeditions.

Western Hup eh: without locality, August and November 1900 (Veitch 

 Exped. No. 1609); without locality, A. Henry (No. 7591). Yunnan: Mengtze, 

 mountains, alt. 1800-2300 m., A. Henry (Nos. 9103, 9099). 



This tree is rare in Hupeh and Szech'uan where it is confined to low altitudes 

 in the dry river valleys. It is a rather tall tree with a slender trunk and rather 

 thin wide-spreading branches. It is common on the plateaux of Yunnan where it 

 grows to a considerable size. 



Here may be added an account of Euphoria longana Lamarck of which a photo- 

 graph was taken during the Arnold Arboretum Expedition, but no specimens 

 collected.
