have hitherto seen none that so perfectly answers to Elliott's. de- 
scription as does this plant. 
A description of Dr. Small’s plant is appended : 
Culms at first erect and simple; later decumbent or nearly 
prostrate and branching at every node, forming large spreading 
clumps. In the early and simple state the whole plant, excepting 
the glabrous basal leaves and panicles, is strongly villous; in the 
late and much-branched stage the culm leaves are often glabrous ; 
nodes barbed; sheaths shorter than the internodes, even on the 
branches; ligule a dense ring of long white hairs; basal leaves 
spreading, lanceolate to ovate-lanceolate, 2.5-6 cm. long, 7-12 
mm. wide; culm leaves linear-lanceolate, erect, stiff, particularly 
in the branched state, the primary ones somewhat narrowed into 
a rounded base, 6-12 cm. long, 4~7 mm. wide, the leaves on the 
branches 3—7 cm. long, 3-5 mm. broad, rounded or truncate, but 
not narrowed at the base; panicles glabrous, the primary ones 
exserted, ovate in outline, 5-6 cm. long, the branches not numer- 
ous, ascending, 2.5 cm. long or less, flexuous, bearing 2-6 spike- 
lets, the secondary panicles much smaller, concealed among the 
leaves, their branches shorter and erect with fewer spikelets; 
spikelets obovate, 2.5 mm. long; first scale whitish, nearly orbic- 
ular, about one-quarter as long as the spikelet which it clasps at 
the base, glabrous, one-nerved; second and third scales of equal 
length, broadly oval, green and membranous, 7-nerved, strongly 
papillose-pubescent; fourth scale broadly oval or approaching 
orbicular, apiculate, abruptly narrowed at the base, striate, white 
and chartaceous, about 2.25 mm. long; palet chartaceous, slightly 
shorter than the fourth scale.

Glabrous. Culms 4-6 dm. tall, erect, stiff, simple or sparingly 
branched, leafy ; sheaths loose, often ciliate on the margins, the 
basal ones crowded and overlapping, those at the middle of the 
culm about one-half as long as the internodes, the uppermost 
sheath usually elongated; ligule a ring of short hairs; leaves 
ciliate toward the base, the basal ones spreading, ovate-lanceolate, 
1.5-4 cm. long, the next succeeding erect, lanceolate, acuminate, 
g-11-nerved, longer and gradually reduced in size toward the sum- 
mit of the culm, the lower 7-14 cm., the uppermost 2.5—-6 cm. 
long, panicle finally long-exserted, ovate to oblong in outline, 
7-12 cm. long, its branches ascending, much divided, the lower 
ones 3-7 cm. long; spikelets numerous, purplish, shorter than 
their pedicels, oval, obtuse, about 1.5 mm. long; first scale mem- _
