2. T. Youngii, Hook. f. Handb. N.Z. Fl. 335.—Culms tufted, 
slender, erect, pilose or glabrous, 1-3 ft. high. Leaves mostly at 
the base of the culms and much shorter than them, ;4,—-1in. broad, 
flat, smooth, pilose with long soft hairs; sheaths grooved, glabrous 
or pilose; ligules short, truncate, lacerate, hyaline. Panicle 
slender, very narrow, 2-Sin. long; rhachis pilose; branches short, 
close, suberect, few-flowered, also pilose. Spikelets compressed, 
pale-green or yellow-brown, shining, 1—3-flowered, about in. long. 
Two outer glumes almost as long as the flowering glumes, sub- 
equal or the lower about 4+ shorter than the upper, oblong or 
oblong-obovate, suddenly acuminate, membranous, scabrid along 
the keel. Flowering glumes oblong-lanceolate, shortly 2-cuspidate, 
minutely rough on the back; awn from 4 to + way down the back, 
rather stout, recurved, nearly as long again as the glume. Palea 
almost equalling the flowering gluine. Rhachilla nearly glabrous, 
produced between the flowering giumes and above the upper flower.

Norryu Isuanp: Mount Hikurangi, Adams and Petrie! Tararua Range, 
Buchanan! Sours Isuanp: Not uncommon in subalpine localities, especially 
on the western side. 3000-5000 ft. 
Best distinguished from 7. antarcticum by the much broader oblong or 
oblong-obovate empty glumes; but it is usually a taller and more pilose plant, 
with a narrower panicle. 
3. T. subspicatum, Beauv. Agrost. 88.—Culms densely tufted, 
‘stout or slender, pubescent or tomentose, in New Zealand specimens 
from 2 to 12in. high, rarely more. Leaves numerous at the base 
of the culms and much shorter than them, firm, erect, rather strict, 
flat, more or less downy or almost glabrous, ;4,—3 in. broad ; sheaths 
rather lax, deeply grooved ; ligules short, scarious, lacerate. Panicle 
short and dense, cylindric or almost ovoid, rarely slightly lobed or 
interrupted at the base, $-2in. long; rhachis densely tomentose; 
branches short, erect. Spikelets compressed, whitish or yellowish- 
green, rarely purplish, shining, 2—3-flowered, 4-tin. long. T'wo 
outer glumes unequal, lanceolate, keeled, scabrid along the keel, 
the outer 1-nerved, the 2nd 3-nerved. Flowering glumes oblong- 
lanceolate, 2-cuspidate or shortly 2-awned at the tip, hairy at the 
base, keel scabrid above, sides minutely rough; awn from 4 to + 
way down the back, longer than the glume, straight or recurved. 
Palea about + shorter than the flowering glume, 2-nerved, scabrid 
along the nerves. — Hook. f. Fl. Antarct. i. 97; Handb. N.Z. FI. 
335; Benth. Fl. Austral. vii. 588; Buch. N.Z. Grasses, t. 40a. 
Sourn Istanp: Not uncommon in alpine and subalpine localities throughout. 
AUCKLAND IsnuANnDs: Kirk! CampBELLIsuanp: Sir J. D. Hooker! Usually 
from 3500 to 5500 ft., but descends almost to sea-level in the Auckland Islands. 
A common alpine grass in most countries, extending into both arctic and 
antarctic regions.
