totlected hy Mr. Schomburgk in British Guiana, 43 1 



Psoralen, there remains Indigofera, which cannot well be associated 

 with any other group of LotecE. As at present constituted the genus 

 would mcixidiQ Hemispadon, Endl., Oustropis, Don, and the Cape spe- 

 cies of Reichenbach's Bonjeania. A revision however of the vfery 

 numerous species contained in Indigofera may suggest the separa- 

 tion of some groups, especially the Onohrychioidei of Wight and Ar* 

 nott, including /. echinata of those authors, and /. mantliocarpa of 

 Lindley. Cyamopsis appears also to be referable to Indigoferce.
