182 BOTANY OF SOCOTRA. 



Distrib. Arabia, Nubia, Senegal. 



A species of considerable distribution in tropical Africa and south-west 

 Asia, but commonly confounded with H. undulatum, Vahl, from which it is 

 easily distinguished by the fruit splitting into two parts, each of which is two 

 celled, and has both margins broadly winged.

Dtstrib. Endemic. 



Nearly allied to the widely spread H. indicum, Linn. (Sp. 187 ; Bot. Mag. 

 t. 1837). It may, however, be readily distinguished from that species by its 

 clothing, which is not woolly, its leaves, which are never cordate at the base, 

 and by its fruit, which is much smaller with non-mitriform segments. 



H. longijiorum, Hochst. et Steud. (in Herb. Schimp. Arab. n. 842), a well 

 known Arabian species is also a neighbour.
