Spikelets 1-flowered, unisexual, in pairs 
appressed along the main branches of the 
inflorescence, one pistillate and _ sessile, 
the other staminate and long-pediceled; 
pistillate spikelet terete; glumes about 
equal, membranaceous, several-nerved; 
lemma rather thin in anthesis but becom- 
ing indurate in fruit, longer than the ga elena npiadiedvosy tha Alan tibln 
glumes, with a minute bent beak, the x 1 (Mohr). 
back clothed to a varying degree with 
thickly set unvinate hairs, these becoming adhesive organs in fruit, 
the edges sharply folded inward and the whole lemma becoming 
involute in fruit; palea very narrow, as long as the lemma, 2-nerved, 
membranaceous, iolded around the long style; stigmas 3; staminate 
spikelet laterally compressed on a stiff pedicel as long as the pistillate 
spikelet; glumes thin, the first shorter, 1-nerved, the second 3-nerved; 
lemma as long as the second glume; stamens 6. Erect perennials 
(the base sometimes decumbent) with broad flat blades and open 
panicles, the blades with fine transverse veins between the longi- 
tudinal nerves, petioled (the petiole with a single twist reversing 
the upper and under surfaces of the blade), the nerves running 
obliquely from midrib to margin.
