204 GRAMINEAE. _[Atropis. 
deeply striate; ligules broad, transversely oblong, membranous. Panicle 
narrow-linear, 2-6 in. long, rigid, erect, glabrous; branches few, unequal, 
solitary or 2-nate, more rarely 3-nate, erect, often almost appressed to 
the rhachis. Spikelets 4-+1in. long, narrow-lanceolate, 4—6-flowered. Two 
outer glumes unequal, the longer one about 4 the length of the spikelet, 
lanceolate, 3-nerved; the shorter broader, l-nerved. Flowering glume 
oblong-ovate, subacute, faintly 3-nerved, glabrous, or a fine tuft of silky 
hairs on the callus. Palea nearly as long as the glume, margins ciliate.

This appears to be a distinct species, easily recognized by its stout loosely tufted 
habit, long narrow panicle, and narrow many-flowered spikelets.

Perennial or rarely annual grasses. Leaves flat or complicate or con- 
volute, often setaceous ; ligules scarious. Spikelets 2- to many-flowered, 
arranged in open or contracted often unilateral panicles; rhachilla dis- 
articulating above the two outer glumes and between the flowering glumes. 
Two outer glumes unequal or subequal, empty, persistent, more or less 
keeled, 1-3-nerved. Flowering glumes lanceolate, acute or acuminate or 
awned, rounded on the back or slightly keeled towards the tip, herbaceous, 
5—-T-nerved ; awn from the tip or close to it, straight; callus glabrous or 
nearly so. Palea 2-keeled, more or less 2-toothed, scabrid or ciliolate 
along the keels. Lodicules 2. Stamens 3. Ovary glabrous or minutely 
hairy at the tip; styles distimct, very short; stigmas plumose. Grain 
enclosed within the shghtly hardened flowering glume and palea and 
often adherent to the latter, oblong, concave or grooved in front; hilum 
long, linear. 
A genus of about 120 species, mainly found in the temperate regions of the 
Northern Hemisphere, not so abundant in the South Temperate Zone, absent in the 
tropics except on high mountains. It differs from Atropis in the long linear hilum, 
and from Poa in the same character and in the flowering glumes being more or less 
rounded on the back and often awned.
