11. P. panicle branching, expanding, capillary; 

 spikes 3-flowered, glabrous, on long peduncles ; 

 leaves linear, very long. Elliot, 



Slender Meadow-grass* 



An exceedingly delicate and slender plant, well described 

 by Mr. Elliot. About a foot high ; not unfrequently of lower 

 stature. In the shaded low woods of Jersey, common ; this 

 side of the river in similar places, less frequent. Perennial ? 

 August. 



12. P. culm erect, smooth, jointed, striate. Leaves 

 linear-lanceolate scabrous on the margin, nerved. 

 Ligula white, bifid, retuse. Panicle crowded 

 and narrow. Branches of the panicle 2-3, con- 

 ferted. Cal, 2-valved, less than the corolla, 5-7- 

 flowered with valves white at the apex obtuse 

 or acute. Cor, 2-valved, exterior valve ovate ob- 

 tuse 5-nerved smooth. Stam, often 2. Seed ob- 

 long and obovate. Muhl, 



Not the Poa obtusa of Nuttall. Perhaps Briza vi- 

 rens, Walt. ? but certainly not of L. 



Blunt- flowered Meadow-grass, 



In the same spongy swamp, near Kaighn's point, already 

 particularly mentioned. Perennial. September. 



13. P. panicle elongated, almost simply branched 

 at the base, branches erect ; spikelets compressed, 

 oblong-ovate, obtuse, upon very short peduncles, 

 8 to 15-flowered ; valves of the calix acute, near- 

 ly the length of the 3-nerved flowers, inner valve 

 with one nerve, the outer with three ; culm rather 

 weak and compressed ? leaves flat and smooth, 

 stipula obsolete, softly bearded. 



Culm simple, about 18 inches high ; leaves few, rather long, 

 flat, and smooth, a little asperate on the margin ; panicle 

 about 4 or 5 inches long, simply branched near the base, run- 

 ning out almost into a raceme above ; flosculi closely imbrica- 

 ted, compressed ; outer valve 3-nerved, truncate at the point ; 

 stamina 3, short ; styles slender, simply pennate.
