FAGACEAE. — CASTANOPSIS 199 



florescence. The perianth segmenta are from 1 to 1.5 mm. long, broadly ovate- 

 rotundate to orbicular, ciliolate and nearly or quite glabrous without; the stamens 

 are about 6 mm. long and at their base there is a conspicuous tuft of white villose 

 hairs. The male flowers are white and the aments are produced in great quantities 

 and when it is in flower the tree is quite conspicuous. 



This species is closely related to C tribuloidcs A. De Candolle and especially to 

 the var. longispina King, which may be distinguished by its pubescent branchlets 

 and large leaves. In western Hupeh C. Fargesii is colloquially known as the Tsze- 

 li-tzu-shu. 



A picture will be found under No. 317 of the collection of Wilson's photographs 

 and also in his Vegetation of Western China, No. 148.

This is a very distinct and remarkable species characterized by the dense and 

 persisting yellow-brown villous tomentum on the shoots, on the under side of the 

 leaves and on the ripe fruits, by the long and massive fruiting spikes and by the
