This species is fairly common at low altitudes on Mt. Omei and in the surround- 

 ing country. It is a low tree of no great size, but with widespreading branches. 

 Like all species of Castanopsis it is evergreen, and the contrast between the rufous 

 brown unfolding young leaves and the shining green of the upper surface of adult 

 leaves is striking.

This tree is common at low altitudes in western Hupeh and in eastern Szech'uan, 

 and is the only species from that region which has spinescent fruit. It is also 

 fairly common in western Szech'uan, where it grows in company with other species. 

 It is a handsome evergreen tree from 15 to 33 m. tall, with a trunk from 1 to 4 m. 

 in girth and widespreading branches. The leaves vary in degree of dentation and 

 the under side of the leaf is pale grayish or rusty brown. The male aments which 

 have not been described are solitary in the axils of minute, caducous scales or oc- 

 casionally in the axils of young foliage leaves. Often the weak lateral floriferous 

 branchlets are very short and quite leafless and give the impression of a panicled in-
