Socotra. On the hills in rocky places near Galonsir. B.C.S. n. 268. 



Distrib. Endemic. 



A species referable to Boissier's section Lyciopsis which includes but one 

 Arabian species E. cuneata, Vahl (Symb. ii. 53 ; Boiss. in DC. Prod. xv. 2, 1>7; 

 Jaub. et Spach 111. PI. Or. tt. 463, 464), one of the most frequent plants of 

 Aden. Our Socotran plant is nearly allied to this species, like which it produces 

 a gum-resin. But there are sufficient characters for distinction in the 

 nonspiny habit, the absence of fasciculate leaves, the broader and more obovate 

 leaves, and the smaller inflorescences of our plant. Our specimens are unfor- 

 tunately imperfect, and do not show mature female flowers.
