9. TEPHROSIA. 



Tephrosia, Pers. Synops. ii. 328 ; Benth. et Hook. Gen. PI. i. 496. 



A considerable genus, widely spread in warmer regions of both worlds, but 

 with its headquarters in south Africa and tropical and subtropical Australia. 

 A few species are North American. Of the six Socotran species, one is endemic, 

 three are entirely tropical African, of which two are restricted to the northern 

 districts, one species is common to north tropical Africa and south-west Asia, 

 and the fifth is cosmopolitan in the tropics.

Socotra. On the cliffs south-west from Galonsir at an altitude over 

 1500 feet. B.C.S. n. 180. 



Distrib. Endemic. 



A lovely little species, with conspicuous purple flowers, and very strongly 

 scented. We only found it in one locality near Galonsir. 



It is very distinct, the trifoliolate leaves and the solitary axillary flowers being 

 an uncommon feature in the section Brissonia to which it belongs, and with 

 the small habit of the plant separate it from all other species.
