Var. recurvata, Hack. MS.—Awn of 4th glume inserted on the middle of 
the back of the glume, slightly geniculate above. Spikelets rather larger.

tain districts from the East Cape and the Ruahine Mountains southwards.

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. recwrvata approaches H. alpina in the awn 
of the 4th glume, but the panicle, &c., is different. 
3. H. Brunonis, Hook. f. Fl. Antarct. i. 93, t. 52.—Culms laxly 
tufted, inclined at the base, erect above, glabrous, leafy, 1-14 ft. 
high. Leaves shorter than the culms, }-4 in. broad, rather strict, 
suberect, linear-subulate, involute, subcoriaceous, glabrous, deeply 
striate on the inner face, pale shining green; sheaths compressed, 
striate ; ligules ovate, scarious. Panicle inclined or nodding, shin- 
ing, rather dense, ovate-lanceolate, 3-5 in. long by 1-14 in. broad; 
rhachis slender, glabrous ; branches suberect, the lower about 1 in. 
long. Spikelets $in. long, pedicelled; pedicels sparsely pilose. 
Glumes all membranous; outer 2 much longer than the 3rd and 
4th, sometimes nearly twice as long, lanceolate, long - acumi- 
nate, 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.

The long empty glumes readily separate this from any form of H. redolens. 
12. STIPA, Linn. 
Tufted perennial grasses. Leaves usually convolute, rarely 
flat. Spikelets narrow, terete, 1-flowered, in an open or contracted 
panicle; rhachilla 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
