(P. flava L., P. serotina Ehrh.). FOWL MEADOW (iKASS, FALSE REDTOI'. 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 witli 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 Ijy 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.) Most, if not all, of the seed of F. triflora on the market appears to be of foreign production. The samples examined have proved to be the worst found among the bluegrasses. It is prol)able that a better grade of seed could be secured from the natural
