CHARACTERS OF TRIBES AND GENERA. Ill 



farther consideration induces me to separate them. The 

 chief distinction lies in the piunas being articulated with the 

 rachis, and in the margins not being notched as in 

 Pleuridium ; the same character also distinguishes it fi-om 

 Phymatodes. The species are natives of India, Nepaul, 

 Sikkim, and Boutan.

Obs. — On account of the venation being similar to that 

 of GoniophleMum, I originally characterised this as a section 

 of that genus. By Presl and others, the species have been 

 placed in diflPerent genera ; and as their habit is entirely 

 different from that of true Goniojildebiitm, I deem it best 

 to adopt Lopholcpis as a distinct genus.
