appressed-pubescent with long silky hairs; sheaths usually 
‘sparingly hirsute at the apex, otherwise glabrous; ligule 
scarious, about 2 mm. long, ciliolate at the apex ; blades 1.5-4 
dm. long, 6-20mm. wide, rough on both surfaces; panicle 
2-4 dm. Jong, 4-6cm. wide, its branches erect, the larger 
7-10 cm. long, spikelets crowded, about equalling the basal 
hairs and one-half again as long as the internodes, the outer 
scales 8-9 mm. long, pilose with long hairs, the fourth scale 
2-toothed at the apex, the teeth long and subulate, the awn 
between them 2-2.5 cm. long, the included portion long and

In low grounds, Tennessee to Florida, ¥ west to Mississippi. 
Type collected by Dr. J. K. Smali, to whom I take pleasure 
in dedicating it, on Stone Mt., De Kalb Co., Ga., Sept. 6— 
12, 1894. The following specimens are also referred here: 
Tennessee: Banks of Hiawassee River, McFarland, A. 
futh, Aug. 1894, distributed as &. brevibarbis. 
Georgia: Yellow River, near McGuire’s Mill, Gwinnett 
Co., John K. Small, July 20, 1893. 
Florida: Chapman. 
Alabama: Montgomery, G. A¢cCarthy, Aug. 1888, dis- 
tributed as /. alopecuroides. 
Mississippi: Starkville, S. 47. Tracy, Oct. 16, 1895, dis- 
tributed as E. stricius 
Related to &. contortus, Ell., but from that species it is 
clearly distinct. In £. contortus the summit of the culm and 
the panicle axis are glabrous or but slightly pubescent, and 
the spikelets are considerably smaller. 
MANISURIS TUBERCULOSA. 
A glabrous tufted perennial. Culms somewhat compressed, 
8-12 dm. tall, stout, branched for about the upper two-thirds, 
the branches erect; sheaths broad, much compressed, keeled, 
striate; ligule scarious, about r mm. long; blades erect, 3 
dm. or less long, 3-7 mm. wide; spikes finally exserted, 6- 
10 cm. long, straight, the rachis barely if at all constricted at 
the nodes ; sessile spikelets about 4 mm. long, about equaling 
the internodes, the first scale with very short transverse wrin- 
es, or very rarely without wrinkles, the wrinkles tubercle- 
like, irregularly disposed; pedicellate spikelets reduced to 1
