Western Szech'uan: Ya-chou Fu, thickets, alt, 1000 m., June 

 1908 (No. 3553; tree 10 m, tall, girth 1.2 m., flowers whitish); Mt. 

 Omei, June 1904 (Veitch Exped. No, 4753; tree 13 m, tall); same lo- 

 cality, E, Faher (No. 57). 



This small tree with pale, fairly smooth bark is very rare in western Szech uan. 

 Our specimens are male and Faber's consist only of leafy shoots, but so far as 

 the material goes we can find no difference between them and specimens from 

 Japan, where the tree ia confined to the warm, southern districts. 



Here may be added another species not collected during the Arnold Arboretum 

 expeditions.
