ENGLISH BOTANY, 
If made into hay the seeds are scattered wherever the hay is carried. It has spread 
all over the United States, no doubt taken there in grass seeds. 
Tribe XI FESTUCEJ:. 
Spikelets open during flowering, arranged in a lax open panicle, or 
more rarely in a compact spikelike panicle, rarely unilateral on the 
branches of a compound spike, or distichous in a simple or sub- 
simple spike or raceme, cylindrical or laterally compressed, each con- 
taining 2 to many perfect florets, very rarely with but a single one. 
Glumes shorter than the florets, rarely equalling them. Pales herba- 
ceous, or at length parchmentlike, the lower one rounded or keeled 
on the back, obtuse or pointed, without an awn, or with a straight 
dorsal or apical awn, which occurs chiefly in the species of those 
genera which have very numerous florets much longer than the 
glumes. Stamens 3, rarely 2 or 1. Styles very short or absent; 
stigmas protruded at the base of the florets, between the margins 
of the pales. Caryops scarcely compressed, usually with a furrow 
on the inner face. 
GENUS XX VIL—T R I O D I A. R.Br. 
Spikelets shortly stalked, arranged in a nearly simple distichously 
8ubracemose panicle, scarcely compressed, open during flowering, 
each containing 2 to 5 perfect florets. Glumes 2, nearly equal, as long 
as or a little shorter than the florets, keeled, pointed, but not awned, 
subherbaceous. Pales 2, the lower one rounded on the back, 3-toothed 
at the apex, but not distinctly awned, parchmentlike; upper pale 
entire, 2-ribbed. Lodicules 3, somewhat fleshy. Stamens 3. Styles 2, 
short, terminal; stigmas plumose, protruded at the sides of the floret 
between the basal margins of the pales. Carj^ops free, glabrous, oval, 
dorsally compressed, flattened on the inner face, but not furrowed, 
crowned by 2 minute points.
