very short, pubescent. Spikelets shining, narrow, terete, |-f in., 
2-5-flowered (uppermost flower male or rudimentary), arranged on 
the branches of a narrow, erect panicle 4-5 in. long. Rhachilla 
hairy, jointed between the flowers, prolonged. Empty glumes 2, 
nearly equal, glabrous, thin, lanceolate, as long as the whole 
spikelet, often tinged with purple, keeled, 3-5-nerved. Flowering 
glumes concave, thin, hairy, fringed, lanceolate, 7-9-nerved, the tip 
deeply 2-lobed ; lobes prolonged as awn-like points, much longer 
than the glume but shorter than the rigid, twisted awn inserted 
in the cleft, the glume thus appearing as 3-awned. Stamens 3. 
Style 2, distinct, feathery. Grain oblong, free, enclosed within 
the persistent glumes. 
Huttoo. — Temperate Himalaya, 10,000-14,000 ft. 
Tribe VII. Chloridese. 
36. TRIPOGON. From the Greek tri, three, and pogon , a 
beard, referring to the 3-awned flowering glumes of some species. — 
Tropical and warm regions in Asia and Africa. 
Perennial, glabrous ; stems tufted, slender. Leaves as long as 
the stem or longer, very narrow, flat. Ligule minutely hairy. 
Spikelets flattened, J-J in., 3-10-flowered (the upper 1 or 2 flowers 
usually male), sessile in 2 opposite rows along one side of a solitary, 
slender spike. Empty glumes very unequal, the lower the shorter, 
stiff, pointed, keeled, 1-nerved. Flowering glumes thin, ovate, 
concave, base minutely hairy, tip 2-toothed or jagged, 3-awned or 
with a single very minute awn. Stamens 3. Styles 2, short, 
distinct, feathery. Grain narrowly oblong, free within the 
persistent glumes. 
Flowering glume 1-awned ; awn very minute . . .1. T. dbyssinicus. 
Flowering glume 3-awned ; awns long . . . .2. T.filiformis. 
1. Tripogon abyssinicus, Nees; FI. Br. Ind. vii. 287. Stems 
6-24 in. Spike 1-10 in. Spikelets rather distant, 3-6-flowered. 
Empty glumes narrowly lanceolate. Flowering glumes : tip 
irregularly 2-toothed or 2-lobed or jagged, with a very minute 
awn hardly projecting beyond the lobes or teeth. 
Simla. — W. Himalaya, 5000-7000 ft. — W. Asia, Tropical Africa. 
2. Tripogon filiformis, Nees ; FI. Br. Ind. vii. 288. Stems 4-16 
in. Spike l|-8 in. Spikelets crowded, 4-10 -flowered. Lower 
empty glume ovate, broadly lobed on one side ; upper narrowly 
lanceolate, sharply toothed on one or both margins near the top. 
Flowering glumes : tip 2-toothed, teeth acute or jagged, a long awn 
inserted in the cleft and a shorter awn on the outer side of each 
tooth, the glume thus being 3-awned, middle awn twice as long as 
the glume or longer. (Fig. 196.) 
Simla, common. — -Temperate Himalaya, 5000-10,000 ft.
