whole fascicle in a spathe, and the spathes on branches of a

A tall grass often 6-8 ft. with a rather stout perennial 

 rootstock, flat leaves 12-18" often 1" broad and glume IV 

 of the perfect sessile spikelets with a geniculate awn j-J* long. 

 A very common forest grass. Fls. Nov. 



In sub.-sp. mutica Gl. IV is very rarely awned. I am not sure whether 

 this occurs in our area, iut there are two varieties which look very 

 distinct in the field, viz., one in which the small f ew-fld. spathes, which are 

 often purple, are closely arranged on a spike, and another in which the 

 spathes with dense clusters of spikelets are widely separated on the 

 usually flexuous rachis. 



22. Anthistiria, L. 

 Tall grasses. Spikelets in capitate spikes, the four lowest 

 bract-like, male or neuter, in a whorl or decnssate pairs 

 and forming an involucre to one or few sessile 2-sexual 

 spikelets and two or more pedi celled spikelets. Spikes sub- 

 tended by a bract or spathe, fascicled, the fascicles panicled or 

 Bub-solitary on the branches of the copious panicle. Sessile, 

 spkt. linear- oblong, Gl. I coriaceous not keeled ; II coriaceous 

 3-nerved, keeled ; HI hyaline 1-nerved ; IV usually reduced to 

 a very long and stout awn, or awn 0. Ped.-spkt, male or 

 neuter awnless.
