Spikelets depressed biconvex, not turgid, oblong, usually obtuse, 
solitary, sessile, and alternate, in two rows on one side of a 3-angled 
rachis, the back of the fertile lemma turned from the axis; first glume 
wanting; second glume and sterile lemma equal, the lemma without 
a palea; fertile lemma and palea indurate, the 
lemma, oblong-elliptic, usually obtuse, the mar-
