ERAGROSTIS POi^OIDES (Beauv.), var. MEGAS- 
TACHYA (Link). 
(Pungent JVEeadow Grass.) 
Culms decumbent at base, 1 to 2 feet high; sheaths 
pilous at throat; ligule short, bearded ; panicle spreading, 
oblong or pyramidal; branches capillary, solitary or in 
pairs, flowering nearly to the base; spikelets about twenty- 
flowered, pilous in the exils; outer glumes about equal, 
very acute, rough on the keel ; flowering glume acute, 
smooth, strongly three-nerved; palet much shorter than 
its glume, hyaline, with rounded or obtuse apex and 
ciliate margin. 
Abundant in garden soils in Northern and Southern 
Colorado. It has a disagreeable odor and comes to 
maturity late in the season. It has, probably, no agricul¬ 
tural value.
