POA SYLVESTRIS (Gray). 
Culms erect, flexuous, flattish, leafy; leaves 
smooth, 3 to 6 lines long; ligule elongated ; panicle close; 
branches very scabrous; spikelets two or three-flowered • 
glumes purple tipped, scabrous on the mid-rib, nearly 
equal, acute; flower glumes obscurely nerved, hairy on 
the lower half of mid-vein and margin, webby at base; 
palet acute, two-nerved, margined, ciliate, but little shorter 
than its glume; panicle pale green, slender, branches 
mostly in 5s. 
This is a pale green, slender grass, growing in 
meadows. It is worthy of trial. 
POA EATONI (Watson). 
Stems tufted, purplish at base, 2° high, from fibrous 
roots; ligule elongated ; sheaths and upper surface of 
leaves minutely scabrous; panicle close, narrow; branches 
solitary or scabrous, in 2s, rarely in 3s; outer glume acute,

rous, purplish apex, acuminate, scarious ; flower glume 
five-nerved, acute, scarious, brownish apex; palet equals
