Psoralea, there remains Indigofera, which cannot well be associated 

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

 would include Hemispadon, EndL, Oustropis, Don, and the Cape spe- 

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

 numerous species contained in Indigofera may suggest the separa- 

 tion of some groups, especially the Onobrychioidei of Wight and Ar- 

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

 Lindley. Cyamopsis appears also to be referable to Indigoferce.
