Socotra, Common on the plains. B.C.S. n. 149. Schweinf. n. 722. 

 Distrib. Aden. 



I originally published this species under the name C. dubia. This name, I 

 find, has been already given to an Indian plant (Grah. in Wall. Cat. 5404 ; 

 Baker in Hook. Flor. Brit. Ind. ii. 73), and I have therefore here renamed 

 the Socotran plant. 



This plant, which in its general habit and structure is thoroughly 

 Crotalarioid, resembling much the species last described — C. strigulosa — and 

 like it having leaves of diverse forms, differs so decidedly from the type of the 

 genus that it is with difficulty one can include it as a species. The fruit is not 

 at all inflated or tumid, and the valves are quite thin and membranous with 

 beautiful veining. In addition, there is a divergent character in the stigma, 

 which is distinctly two-lobed, each lobe being flattened and pointed. But if 

 we exclude the plant from this geuus, I can find no other in which to place it, 

 and the characters are perhaps hardly sufficient to warrant at present the 

 creation of a new genus. 



Schweinfurth, when at Aden recently, discovered the plant there, and has 

 sent home specimens, now in Kew Herbarium (Schweinf. Exp. Bieb. n. 44). 

 He says it grows abundantly " behind Ma'alla." I find the Aden plant does 

 not show distinctly the lobing of the stigma visible in the Socotran flowers.
