Readily distinguished from the only other species from the region — 

 D. radiata, Lam. (Kosaria, Forsk. Ft. JSgypt. Arab. p. 164, t. 20) and 



I). gigas 3 Schweinf. (Balf. in Trans. Roy. Sue. Edinb.xxxi. t. 95.) The 



'former has less crowded tubercles, leaves cordate at the base and 

 smaller receptacles ; and the latter is an altogether larger and different 

 plant. Both agree in having fleshy stems and stellate receptacles. —
