Description: — A much-branched spreading shrub, sometimes 18 
inches in diameter. Branches white-tomentose and in the upper part 
hairy. Leaves J | inch long, ovate, subglobose, farinose, glandular- 
pubescent ; beneath each leaf is a tubercle decurrent on the stem. Leaves 
sessile, not rarely pseudopposite on some of the upper branches. 
Flowers in dense spikes ; bracts spirally placed, suborbicular, whitened 
on the margins; filaments conspicuously exserted. 
Locality : — Eastern shore of the Isthmus near Barrier-Gate (Defl.). 
Distribution: — Arabia, Nubia, N. Africa, Canaries. 
Note : — It seem^ strange that Schweinfurth who appears to have 
closely examined the eastern shore of the Isthmus does not mention this 
species. Is it not possible that Defiers mistook S. fruticosa Forsk. for 
8. vermiculata Forsk., as these two plants resemble each other a good 
deal ?
