sessile and closely imbricate on one side of a continuous rachis, hill 
disarticulating above the glumes; first glume small, hyaline, aedis the

divergent awn: lemmas rather papery, 3-nerved, villous on the lateral nerves 
and eallus, bearing a short straight awn on the back just below the apex, e 
first and second lemmas empty, the third enelosing a perfect flower, the upper 
to 3 empty and successively smaller. [Cteniwm Panz.]—Twe lve species, of m 
warmer regions; mostly American E M. GRASSES.

club-shaped rudiment; unc somewhat unequal, the first shorter, narrow, 
acute: lemma keeled, usually broad, 1- to 5-nerved, often villous on the callus, 
and on the keel or marginal nerves, awned from between the short teeth of a
