1251. C. SETOSA Scribn. L. 164. Comanche Spring. Aug 



1849. 



"In masses near thickets and on slopes." 



Glabrous-leaved form; spikes varying from narrowly cylin- 

 drical to narrowly conical. Near C. composita Scribn., but most 

 ^ of the spikes narrower than in that species and longer and more 

 acuminate than in C. caudata. It is probable that these related 

 forms are all one species under varying conditions. 



1252. CHRYSoroGON AVENACEus Benth. L. 167. (Co- 



manche Spring). Sept. 1849. (211; IV-740).

1254. E. VIRGINICUS L. L. 569. New Braunfels. May 1851. 



A form differing from the normal of the species by its narrower 

 empty glumes and elongated 4-5-flowered spikelets. Apparently 

 approaching E. striatus Willd.

L. 176. (Comanche Spring). Oct. 1849. (IV- 

 725).

 cate leaf with short (6 mm.) ligule.

fels. 1850). (III-566).
