DEYEUXIA LAPPONICA (Kth.). 
Lower glume scarious, almost equal, alternate at 
apex, scabrous on keel and purplish below; flowering 
glume of similar texture, shorter than glume, two-toothed 
at apex; furnished with a yellowish, twisted awn, bent 
about the middle, and purplish ; palet very narrow, two¬ 
toothed, hyaline; anthers purplish; rhachis protruding 
beyond the flower, into a villous bristle. In this plant 
the outer glumes are very much shorter than the flower¬ 
ing glume; sheaths and leaves finely silicate, scabrous; 
ligule lacerate, oblong, rounded and truncate; outer glume 
lanceolate, very acute, scabrous on keel; flowering glume 
two or three-toothed, perhaps lacerate, with awn; lower 
outer glume three-nerved, upper one-nerved ; flowering 
glume with lacerate, two-cleft apex, shorter than glume, 
furnished on back with a bent, diverging awn, a tuft of 
silky hairs on each lower margin ; a silky bristle standing 
opposite the palet, which is narrow, thin and 2 to 4 ' long; 
panicle close, spicate, branches in 5s : plant 1 foot high. 
Found near Little Muddy in unirrigated meadow. 
DEYEUXIA STRICTA (Trin). 
Culms 3 to 5 feet high, stout, leafy; sheaths loose 
and smooth ; leaves narrow, involute, pale, finely scab¬ 
rous ; ligule elongated, lacerate; panicle loose, densely 
flowered, 3 to 6 inches long; branches erect, appressed in 
5s or 7s, very scabrous; outer glumes nearly equal, scab¬ 
rous all over, very acute, the lower three-nerved, the 
upper and longer one-nerved; flowering glume promi¬ 
nently five-nerved, two to four-toothed at apex, shorter 
than the glumes; a slender, straight awn—little, if at all, 
exceeding it, from near the middle; the ring of fuscous 
hairs copious and nearly the length of the glume; palet 
small, narrow, two-nerved. 
This very robust species is found at high elevations 
in the mountains, growing in moist, but not shady, situa¬ 
tions. It is a promising hay grass, but it is difficult to 
procure seeds in quantity, because of its scarcity.
