and relatively few racemes, the axis 

 and rachis puberulent, has been de- 

 scribed as E. mollis var. longifolia 

 Vasey. It grades into the typical 

 form with broader blades and more 

 numerous racemes; the sterile floret 

 contains a staminate flower. 



Eeiochloa michauxii var. simp- 

 soni Hitchc. Resembling the narrow- 

 leaved form of the species; racemes 

 few, appressed; sterile lemma empty.

Eriochloa villosa (Thunb.) Kunth. 

 Tall annual with few to several racemes, the 

 rachis and pedicels very woolly, the rather 

 blunt, turgid pubescent spikelets about 5 

 mm. long. O — Ballast, near Portland, 

 Oreg., occasionally cultivated; adventive in 

 Colorado. Eastern Asia. (Had been confused 

 with E. nelsoni Scribn. and Smith of Mexico.) 



133. BRACHlARIA (Trin.) Griseb. 



Spikelets solitary, rarely in pairs, subsessile, in 2 rows on one side of a 

 3-angled, sometimes narrowly winged rachis, the first glume turned toward 

 the rachis; first glume short to nearly as long as the spikelet; second glume and 

 sterile lemma about equal, 5- to 7-nerved, the lemma enclosing a hyaline palea 

 and sometimes a staminate flower; fertile lemma indurate, usually papillose- 

 rugose, the margins inrolled, the apex rarely mucronate or bearing a short 

 awn. Branching and spreading annuals or perennials, with linear blades and 

 several spreading or appressed racemes approximate along a common axis.
