 {C'hloristexensis^eish, ibid, 23 : l.ol. 1896.)— A smooth, glaucous perennial 3-6 dm. 

 (lo-2°) high, the crowded lower sheaths compressed, with flat leaves and two 

 to eight slender, terminal, digitate spikes 10-18 cm. (4'-7') long, which are 

 pilose and naked at the base or with a few scattered spikelets. Spikelets (a), 

 exclusive of awn, about 4 mm. (2") long; glumes four, the outer ones often pur- 

 plish, the first three-fourths as long as the second; third glume (e) 4 mm. (2") 

 long, bearing an awn G-9 mm. {^"-4h") in length. Palea as long as the glume.— 

 Texas. (Mexico?) 



The larger third and fourth glumes, together with the glabrous midnerve 

 of the former and different shape ot the latter readily distinguish this from 

 C. verticillata.
