Elatostema (n. sp. in ms. by C. B. Robinson.) 
Field-note:—Succulent herb; stem smooth, brown, terete, 
fleshy, sparingly branched, ascending or ultimately recurved; 
leaves descending, membranous, dark green above, much 
paler green beneath; inflorescence greenish white, arranged 
in the leaf axils along the upper side of the branches.
