florescence. The perianth segments 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. tribuloides A. De Candolle and especially to 
the var. longispina King, which may be distinguished by its pubescent branchlets 
"ws aig leaves. In western Hupeh C. Fargesii is colloquially known as the Tsze- 
-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.
