Poa triflora Ehrh. (P. flava L., P. serotina Ehrh.). 
FOWL MEADOW GRASS, FALSE REDTOP. 
Spikelets 2-4 flowered; florets 2-2 mm.long, lanceolate or ovate-lanceolate as 
viewed from the back, broadly keeled and strongly arched at the back, light brown 
and usually strongly tinged with yellow above the middle, sometimes purplish, 
margins of the glume narrowly infolded below the middle or quite to the apex, 
which is hyaline-edged, expanded but scarcely flaring; intermediate veins indis- 
tinct; keel and marginal 
veins silky pubescent below 
the middle; basal web 
slight; palea nearly or quite 
equal to the glume, finely 
hispid-ciliate on the keels, 
which are mainly covered 
by the glume margins in the 
lower florets; rachilla seg- 
ment slender, glabrous or 
sometimes slightly scabrous, from one-fourth to one-half or two-thirds the length of. 
the glume; aborted floret of the sterile rachilla segment often prominent and nearly 
as long as the rachilla segment; grain 1 mm. long, comparatively robust and smooth, 
scarcely keeled or grooved, semitranslucent. (Fig. 8.)

views; d and e, side views; /-h, front views; h, a terminal floret. 
Most, if not all, of the seed of P. trzflora on the market appears to 
be of foreign production. The samples examined have proved to be 
the worst found among the bluegrasses. It is probable that a better 
grade of seed could be secured from the natural meadows in this coun- 
try where this species often constitutes the principal grass. The 
seeds of P. triflora are very similar to those of Canada bluegrass and 
wood meadow grass.
