leaves seven to eleven ; sheaths smooth ; blades linear,, 
2 to 4.inches long, 1 to 3 lines wide, scabrous; sterile stems 
4 to 8 inches long, leafy to the top; panicle 2 to 4 inches 
long; branches sessile, contracted into an interrupted 
spike; spikelets crowded, one-flowered; empty glumes 
equal, membranous, one-nerved, tipped with awns equal¬ 
ing the glumes in length, and with awns one-third longer 
than the flowering glume; flowering glume ovate, lance¬ 
olate, acute, entire, not awned, membranous, three-

equal, hyaline, two-nerved palet. 
On ditch banks and in native meadows ip the valley 
of the Poudre. Valued as a forage grass. 
FESTUCA SCABRELLA (Torr.). 
(Bunch Grass.) 
This grass forms the largest bunches of any of the- 
so-called bunch grasses. The specimen bunch, which I 
have before me, measures 12 inches across at the base. 
It is very compact; the stems are numerous, 34 to 38 
inches long, slender, smooth, two to three-leaved; the 
blades of the stem leaves have all fallen, leaving the* 
naked, scabrous sheaths ; radical leaves very numerous, 
12 to 24 inches long, very narrow, involute, scabrous; 
panicle 4 to 7 inches long; branches 1 to 1J inches- 
long, single or in pairs, rhachis scabrous; spikelets 
three to five-flowered; empty glumes membranous,, 
the lower one-nerved, one-third shorter than the 
three-nerved, upper one; flowering glume acute, 
tipped Avith a very short aAvn, five-nerved, scabrous,, 
scarious margined; palet two-nerved, bifid, equaling the 
glume. 
In the mountains, at G,000 to 8,000 feet. Much, 
valued as a range grass.
