A tall much-branched suberect or suhscandent grass 1-3 ft. high with rigid 

 stems thicker than a crow-quill. Leaves very variable, from broadly ovate aud 

 4-3 in. by J-IJ in., to narrowly lanceolate and 1-4 by i-J in., caudate-acuminate, 

 flaccid or rigid, glabrous or hairy, margins serrulate or ciliate with stiff hairs, 

 nerves obscure ; ligule rounded. Spikes few or many, 4— 2 in., rachis sparsely hairj, 

 joints about half as long as the spikelet, margins cilinte. Spikelets J-J in., vei-y 

 narrow j gl. I acute, tip hyaline 5-7-nerved, dorsally smooth or muriculate ; II lan- 

 ceolate, 3-nerved; III shorter, linear-oblong, acute ; IV hyaline, awn about 1 in. 

 long. PedicelledL spikelets linear-lanceolate, keels hispidulous; anthers perfect, — 

 Eackel has 5 varieties and subvarieties of this species, but I fail to limit them after 

 studying copious materials.

Stem 1-2 ft,, erect from a geniculate branched rooting (blood-red. Griff.) base, 

 rigid, as thick as a crow-quill or less. Leaves 2-ii in., lanceolate, acuminate, 

 glabrous or sparsely hairy, margins strongly ciliate. Peduncle long, slender, naked. 

 Spikes 1, 2, or few, J-1 in., peduncled ; peduncle and rachis rather stout smooth, 

 with sometimes an empty glume. Spikelets -J in. (red-brown, Qriff.), coriaceous j 

 gl. I 9-nerved; II 3-nerved, acute; III hyahne, oblong, ciliate, l-nerved; IV lan- 

 ceolate, ciliate, awn inserted below the middle, about twice as long as gl. II, palea 

 linear-oblong, ciUate. — The only species in which I have seen a palea to gl. IV.

Stems 2-4 ft., geniculately branched below, about as thick as a dove's quill. 

 Leaves l-2i in., ovate or ovate-lanceolate, finely acuminate and sheaths glabrous or 

 hairy. PedujieZe long, usually naked, slender. Spikes 10-20; 1-3 in. ; rachis and 

 pedicels nearly glabrous. Spikelets i-i in., purplish ; gl. I variable in the number 

 and size of tubercles on the nerves ; IV not much shorter than II, awn subbasal, 

 shortly exserted. Anthers very large (sometimes 2 only ?) — Resembles a very large
