Echinochloa crusgalli var. 

 mitis (Pursh) Peterm. (Fig. 1087.) 

 Racemes dense, mostly somewhat 

 spreading-flexuous; spikelets awnless 

 or nearly so, the awns less than 3 

 mm. long; basal sheaths occasionally 

 hirsute. O — Moist places over 

 about the same area as the species 

 and nearly as common. 



Echinochloa crusgalli var. 

 zelayensis (H. B. K.) Hitchc. (Fig. 

 1088.) Differs from E. crusgalli var. 

 mitis in having less succulent culms, 

 mostly simple, more or less appressed 

 racemes, the spikelets less strongly 

 hispid but papillose, usually green. 

 Small plants resemble E. colonum, 

 but differ in the more distinctly point- 

 ed spikelets, more spreading racemes, 

 and erect more robust culms. O 

 — Moist, often alkaline places, Okla- 

 homa to Oregon, south to Texas and 

 California; Mexico to Argentina, in 

 the tablelands. (T3^pe from Zelaya, 

 Mexico.)
