Also in Tasmania. A puzzling plant, large states of which cannot be clearly 
separated from H. redolens, although usually differing in the smaller size, slender habit, 
shorter and more open panicles, and smaller spikelets, with the empty glumes rather 
shorter than the 3rd and 4th. Sir J. D Hooker referred it to H. borealis in the Flora, 
and to H. alpina in the Handbook. But Professor Hackel remarks that it differs from 
both of these species in the short blunt outer glumes, and from H. alpina, in addition, 
in the much longer branches of the panicle, and in the awn of the 4th glume being 
usually inserted just beneath the apex and not geniculate. Var. recurvata approaches 
H. alpina in the awn of the 4th glume, but the panicle, &c., is different.

tufted, inclined at the base, erect above, glabrous, leafy, 1-1} ft. high. 
Leaves shorter than the culms, #4 in. broad, rather strict, suberect, linear- 
subulate, involute, subcoriaceous, glabrous, deeply striate on the imner 
face, pale shining-green ; sheaths compressed, striate ; gules ovate, scarious. 
Panicle inclined or nodding, shining, rather dense, ovate-lanceolate, 3-5 in, 
long by 1-1$in. broad; rhachis slender, glabrous; branches suberect, 
the lower about lin. long. Spikelets 4in. long, pedicelled ; pedicels 
sparsely pilose. Glumes all membranous; outer 2 much longer than the 
3rd and 4th, sometimes nearly twice as long, lanceolate, long-acuminate, 
glabrous, 3-nerved; 3rd and 4th each enclosing a male flower, ovate- 
oblong, obtuse, 5-nerved, deeply bifid at the tip, pubescent or pilose, 
margins silky-ciliate, awn rather long, rising from the back a little distance 
below the base of the lobes; 5th similar to the 4th but smaller and much 
less pubescent, usually glabrous at the base. Palea linear-oblong, 1-2- 
nerved.—Handb. N.Z. Fl. (1864) 322; Cheesem. Man. N.Z. Fl. (1906) 856.

The long empty glumes readily separate this from any form of H. redolens.

Tufted perennial grasses, Leaves usually convolute, rarely flat. 
Spikelets narrow, terete, 1-flowered, in an open or contracted panicle ; 
thachilla disarticulating above the 2 outer glumes. Glumes 3; the 2 outer 
empty, usually persistent, keeled, acute, rarely awned; 3rd or flowering 
glume rigid, convolute, terete, 5—7-nerved, usually with a bearded callus 
at the base, tapering upwards into an entire or minutely 2-lobed tip, with 
a long terminal geniculate awn often spirally twisted below the bend. 
Palea 2-nerved, enclosed within the flowering glume. Lodicules usually 3, 
large. Stamens 3, seldom fewer. Styles distinct, rather short. Grain 
narrow, terete, tightly enclosed by the hardened flowering glume and palea. 
A genus of over 100 species, spread over the temperate and tropical regions of 
both hemispheres. Two of the New Zealand species extend to Australia, the third 
is endemic.
