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 glabrous. 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 transverse 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,R. Br. Prodr. (1810) 177.— Very variable in 
size, usually 1-2 ft. high, but often dwarfed to a few inches, and sometimes 
attaining 3ft. Culms tufted, slender, smooth, glabrous or sparingly pilose. 
Leaves shorter than the culms, narrow, flat or involute, often almost

Var. setifolia Hook. FOR. Nov. Zel. i (1853) 304.—Culms more densely tufted. Leaves 
very narrow, terete from the strongly involute margins, strict, wiry, erect. Panicle 
smaller, with fewer spikelets. Flowering glumes less copiously silky, the hairs of the 
upper transverse band shorter.—D. semiannularis var. alpina Buch. in Trans. N.Z.

brown with a searious margin.

Also abundant throughout the whole of temperate Australia. In New Zealand 
this species and D. pilosa are now largely sown as pasture - grasses, especially in the 
northern part of the colony. On stiff clay soils they are far more permanent than most 
introduced species, and might with advantage be substituted for them.

of the stems and much shorter than them, strict, erect, wiry, very narrow, 
involute, filiform or nearly so; sheaths pale, glabrous, deeply grooved : 
ligules reduced to a band of short white hairs. Panicle small, contracted,
