500 GRAMINACEAE. [ Panicum. 
10. P. cinereum, sp. ». — A stout grass, about 3 ft. high, lanuginous 
in all parts with long soft silky grayish hairs. Leaves 12‘ long and 7—9" 
broad, thick chartaceous, silky throughout with appressed hair, the sheath 
ending in the blade with a broad beak-like truncate projection of about 
6” in length, the ligule forming a thick woolly border to it. Panicle 
large and dense, pyramidal, 10—12‘  4—6’, its numerous branches in 
whorls or fascicles and dividing from near the bane the lowest 5—7‘ long; 
rhachis and rays hirsute with spreading hairs. Spikelets as in P. pellitum, 
the third glume glabrous, the two outer glumes hirsute with spreading hairs. 
Stamens short and purple. Styles fimbriate near the apex only.

11. P, torridum, Gaud. Bot. Voy. Freyc. p. 411. — Erect, tufted, clothed 
in all parts with soft silky pale yellowish or fawn- colored hairs. Stems 
—2 ft. high, simple or once dividing, bearded at the nodes and pu- 
cat below, the uppermost leaf below the base of the panicle and not 
overreaching it. Leaves chartaceous, plane, erect, 6—12’ < 4-5", the 
sheaths shorter than their internodes and hairy with spreading eillae, the 
aa with shorter pubescence. Ligule ciliate. Panicle dense, py vramidal, 
6‘ < 1—2'‘, the rays suberect, close, in fascicles of 3—5, dividing from 
near the base, the lowest 2—2'/2‘ long, all densely hairy. Spikelets on 
pedicels shorter than their own length, ovoid-acute, 1'/:—2", clothed with 
spreading ciliae longer than the width of the spikelets. Glumes unequal; . 
the lowest longest, lanceolate-acute, with 3—5 br ownish nerves; the 
second 1/3 shorter, ovate, 5—7-nerved; the third hairy on margins and 
nerves like the outer ones, almost equal to the second, faintly 3 —5-nerved, 
with a minute obtuse hyaline palea. Fertile fioret short, less than half 
the length of the first glume, yellowish. Styles as in no. 5

12. P. monticola, sp. n. — Stems erect from a prostrate rooting base 
and stoloniferous, 8—10’ high, undivided, glabrous, bearing 5—6 leaves, © 
the uppermost one a short distance below the jy Leaves stiff 
chartaceous, 9 blade plane, linear-lanceolate, very acute, glabrate, 
1'/2—3' X 2—3"; the sheaths softly pubescent; ligule ciliate. Panicle 
rather open, 2-3! long, its rays single or in twos or threes, suberect, the 
lowest 1'/2‘; rhachis and rays stiff angular, puberulous. Spikelets on fili- 
form pedicels of more than their own — ovoid-oblong, somewhat obtuse, 
biconvex, 1!/2", purplish-green, glabrous. Sterile glumes ovate, unequal, 
the lowest '/1—1/2 the length of the second, which is l'/2” long and 
7—9-nerved; third glume like the second, but pale and supplied with @
