works, who died in 1833 —Tropical and subtropical regions of the 
Old World. 
Annual or perennial; stems erect or decumbent near the 
base. Leaves narrow, long-pointed. Ligule very short, fringed. 
Spikelets 1 -flowered, similar, in pairs, one sessile, the other stalked, 
each more or less enveloped in a basal tuft of hairs, narrowly 
ovoid, about £ in., on 2-10 simple, jointed, spike-like branches 
spreading from near the top of the stems. Empty glumes 3 ; 
uppermost smaller, thin, transparent, sometimes wanting ; 2 lower 
nearly equal, coloured ; lowest membranous, hairy or glabrous, 
stiff, tip usually truncate ; second rather thinner, acute. Flower- 
ing glume much the smallest, sometimes reduced to a mere 
rudiment, transparent, tip bifid, with an awn in the cleft usually 
long and' slender, sometimes hairy, often bent near the middle, 
the base more or less twisted. Stamens usually 3, rarely 2. 
Styles 2, long, distinct, the upper portion fringed. Grain narrowly 
oblong, free within the outer glumes. 
Stems erect. Spikes distinctly hairy. 
Stems 2-3 ft., robust. Spikes 3-8 in. Hairs red-brown 
or tinged with violet . . . . . . . 1. P. quafrinerms. 
Stems 1-2 ft., slender. Spikes 1-3 in. Hairs white or 
silvery. 
Perennial. Hairs silvery, longer than the spikelets, 
almost concealing them . . . . . . 2. P. mollis. 
Annual. Hairs white, much shorter than the spike- 
lets, only fringing them 3. P.fimbriata. 
Stems decumbent and much-branched near the base. 
Spikes nearly glabrous. 
Stamens 3. Stalks of spikelets minutely fringed . . 4. P. imherbis. 
Stamens 2. Stalks of spikelets glabrous . . . 5. P. nuda. 
1. Pollinia quadrinervis, Hack . ; FI, Br. Lid. vii. 110. Stems 
2-3 ft., erect, robust, leafy. Leaves 8-T8 in., narrow, finely pointed, 
hairy on both surfaces or nearly glabrous. Spikes 3-8 in each 
cluster, densely hairy, rather thick, 2-8 in. ; hairs red-brown, 
sometimes tinged with violet. Spikelets pale yellow-brown. 
Empty glumes 3. Awn rather thick, three or four times as long 
as the spikelet. Stamens 3. 
Simla.— Subtropical Himalaya, 3000-5000 ft.— China. 
This includes P. hirtifolia, Hack . ; FI. Br. Ind. vii. 111. Huegel’s specimen, 
recorded from Simla, on which this species was founded, is not available for 
examination. The two specimens named hirtifolia in Kew Herbarium cannot 
be distinguished from quadrinervis. 
2. Pollinia mollis, Hack . ; FI. Br . Ind. vii. 111. Perennial ; 
stems 10-12 in., erect, slender,, leafy chiefly at the base. Leaves 
2-3 in., narrowly lanceolate, nearly glabrous. Spikes 3-10 in 
each cluster, slender, 1-2 in. ; hairs silvery, silky, much longer 
than the pale brown spikelets and so dense as almost to conceal 
them. Empty glumes 3. Awn slender, three or four times as 
long as the spikelet. Stamens 3.
