I have had great difficulty in disposing of the synonymy of this genus, the species 

 of which are in a chaotic condition, and I regard the result here attained as tentative 

 oiily, some of the synonyms adopted being little better tlian guesses, though the 

 results of much study. The genus is absent in the Wallichian Herbarium of 

 the Linnsean Society, 



* Leaves short, broad, membraifous.
