10. D. pilosa, &. Br. Prodr. 177.—Culms tufted, slender, gla- 
brous or sparingly pilose, leafy at the base, 1-2ft. high, rarely 
more. Leaves usually much shorter than the culms, narrow, 
often setaceous, involute or rarely flat, glabrous or pilose with 
spreading hairs ; sheaths narrow, grooved, pilose or glabrous ; ligules 
reduced to a transverse band of long soft hairs. Panicle 1-4 in. 
long, usually narrow and contracted, sometimes racemiform ; 
branches short, erect. Spikelets about 4in. long, 4-8-flowered. 
Two outer glumes exceeding the flowering glumes, subequal, lanceo- 
late, acute, membranous, 7-nerved. Flowering glumes 7-9-nerved, 
deeply 2-lobed at the tip, the lobes produced into fine awns as long 
or longer than the glume, central awn from between the lobes, ex- 
serted bevond the spikelet, flattened and spirally twisted and often 
dark-coloured at the base, a tuft of silky hairs at the base of the 
callus or pedicel of the glume, a tuft on the margin on each side 
above the callus, sometimes connected by hairs on the back, and 
another marginal tuft on each side opposite to the base of the lobes, 
the sides and back between usually glabrous. Palea broad, obtuse 
or shortly bifid at the tip.—Hook. f. Fl. Nov. Zel. 1.303; Fl. Tasm.

Var. racemosa, Buch. N.Z. Grasses, t. 33(2)B.— Culms very slender, 
drooping. Panicle reduced to a slender raceme of 4-10 almost sessile spikelets.

D. pilosa is technically distinguished from D. semiannularis by the absence of 
the transverse ring of hairs on the flowering glume just below the lobes. 
In the typical state this ring is reduced to a small tuft of hairs on each 
margin of the glume, the sides and back between the tufts being quite gla- 
brous. But occasionally there are a few hairs on the back of the glume as” 
well, and sometimes these become so numerous as almost to form a trans- 
verse ring, thus breaking down the distinction between the two species. D. 
pilosa is also found in Australia, ranging from Queensland to Tasmania and 
West Australia. 
11. D. semiannularis, f. Br. Prodr. 177.—Very variable in 
size, usually 1-2 ft. high, but often dwarfed to a few inches, and 
sometimes attaining 3 ft. Culms tufted, slender, smooth, glabrous 
or sparingly pilose. Leaves shorter than the culms, narrow, flat 
or involute, often almost setaceous; sheaths grooved, glabrous or 
pilose with long spreading hairs; ligules reduced to a narrow 
transverse band of soft silky hairs, those on the outside the longest. 
Panicle 1-4 in. long, usually compact and more or less contracted ; 
branches few, short, erect. Spikelets 4-}in. long without the 
awns, 3-8-flowered. Two outer glumes exceeding the flowering 
glumes, subequal, lanceolate, acute, membranous, 5—7-nerved. 
Flowering glumes 7—9-nerved, deeply 2-lobed at the tip, the
