phologically a subtending leaf sheath); staminate spikelets approxi-

forming a short raceme, the rachis protruding from the orifice of the 
involucre, these ultimate inflorescences borne on the ends of numerous 
branches. Broad-leaved annual.

similar to those of Zea, the glumes firmer; pistillate spikelets single 
and on opposite sides at each joint of the thick, hard articulate lower 
part of the same rachis, sunken in hollows in the joints, consisting of 
one perfect floret and a sterile lemma; first glume coriaceous, nearly
