72 TRIANDRIA DIGYNIA 



obscuroly 5-nerved, somewhat acute, but not acuminate nor mucronate. Fppet 

 2>alca lanceolate, white, with a green keel near each margin, which is doubled or 

 folded in. 

 Hob. Fertile fields, and meadows: common. Fl. June. Fr. July. 



Obs. This was mistaken for the preceding, in my Catalogue ; and seems to have 

 been occasionally confounded with it, by others Indeed it is so closely allied \t 

 F. elatior, that it may be doubted whether it is more than a variety. It is, howev- 

 or, a much more valuable grass: and although not cultivated, has found its way in- 

 to all our best meadows and pastures. It is also a uralized foreigner. 



4. F. nutans, Willd. Panicle slender, diffuse, at length nodding; 

 branches long, in pairs, naked below ; spikeleta lance-ovate, about 3- 

 flowered ; florets smooth, awnless, and nearly nerveless. Meek-, Hot.

 Nodding Fbstuca. 



Jloot r -nnial. Culm erect, aboul .'» feet high, rather slender, simple, glabrous; 

 nodes blackish. Leaves linear-lanceolate, strongly nerved, somewhat scabrous, 

 6 or 8 to i-2 Inches long, deep green \ sheath* nerved grooved, often pilose (glabrous, 

 Muhl) ; ligule short, serrate. Panicle Sl< nderand very loose, few-flowered ; low- 

 er branches in pairs, upper ones single. Spikelet8'2to6-f\ iwered, (usually 3-flow- 

 eredi) on subdivisions, or peduncles near the extremity of the long, slender, scab- 

 rous branches. Florets rather tumid. Glumes unequal, lanceolate, acuminate, 

 scabrous on the keel. Palea coriaceous, smooth ; lower one lance-ovate, mostly 

 acute, nerveless, or very obsxureh • . r\vi\, margin not scarlous ; upper one lan- 

 ceolate, as long as the lower, bide mate at ap ex, the margin folded in, forming a 

 keel at each bonier, 

 Hub. Moist woodlands: West Chester; Brandy wine: frequent, Fl. June. Fr. July. 



Obs. This is allied to Poa ; but the palea are not scarlous on the margin It is 

 not a grass of much value,— being rather s litary in its habit, and chiefly confined 

 to woodlands. Eight or nine additional species have been described in the United 

 States.

Spikelets long, linear, many-flowered. Glumes 2, unequal, membran-
