7. E. Mannii, Wedd. in DC. Prodr. xvi. i. 178. A monoecious

 somewhat succulent, 6 in. to 1 ft. high, 1-1 -| lin. thick, surface rough 

 with crowded linear cystoUths, somewhat hispidulous in the younger 

 portion. Leaves crowded on the upper third of the stem, a few

 wide, lateral nerves 4-6 on each side, the two lowest springing from 

 the midrib above the base, that on the narrow side appreciably 

 higher, about J in. from the base, and reaching to about the middle 

 of the leaf; upper face glabrous, densely covered with linear white 

 cystoliths and punctulate, lower face sparsely hispidulous on the
