Rhachis articulate, moniliform, the single joints obovate, dotted with rust- 
colored spots, separately deciduous with the nuts, which are tightly clasped 
by the broad subcoriaceous wings extending along the entire side of the 
joint. Nuts black, oblong, apiculate, about as long as the joints and half 
as long as their glumes, rather plane-convex, the. convex face next to the 
rhachis and the ie a strongly rid ds: _ © ada. l.e. p. 44. — Beklr. in
