Stem very stout, rooting at the thickened nodes ; branches ascending 8-14 in., 

 glabrous. Leaves on the creeping stem 1-2 in., closely imbricating in two series, 

 the blades refiexed at right angles to the erect short open sheaths, softly tomentose 

 on both surfaces ; lower sheaths ^1 in., villous ; lignle short, bearded with very 

 long hairs. Spikes 2 in., joints and pedicels about half as long as the spikelets, stout, 

 concavo-convex, shortly villous, truncate. Sessile spikelets ^ in., callus very large, 

 glabrous ; gl. I thickly coriaceous, dorsally convex, ciliate above the middle, margins 

 broadly incurved below the middle; II rather longer, rigid, dorsally rounded below 

 the wing; III ovate-oblong, obtuse, margins ciliate, paleate, male; palea chartaceous, 

 obovate, 2-nerved, nerves meeting at the tip with very broad hyaline wings above 

 the middlqj; IV = | II, 3-nerved below the middle, awn about twice as long as 

 the spikelet; palea lanceolate, nerves ciliate, Pedicelled spikelets laterally com- 

 pressed ; gl. I convex, broadly winged, villous ; I V shortly awned or awnless. — The 

 habit of the only good specimen I have seen is very peculiar.
