Poa. | GRAMINEAE. 189 
One of the few endemic plants of the island, and a very distinct species. It is 
best characterized by the short strict culms, the deeply laciniate ligule, and the short 
and narrow much contracted panicle. Kirk states that its nearest allies are P. foliosa 
and P. anceps. It doubtless belongs to the P. foliosa group; but it has little affinity 
with P. anceps, from which it differs in the mode of growth, in the leaves, and 
particularly in the deeply laciniate ligule, which is widely different from the truncate 
rim-like ligule of P. anceps, also in the acuminate and inourved flowering glumes and 
the large anthers. The particulars given above have been mainly drawn from my 
“Vascular Flora of Macquarie Island” (Australian Antarctic Expedition, vol. vii, 
part 3). 
o. P. novae-zealandiae Hack. in Trans. N.Z. Inst. xxxv (1903) 381.— 
Perennial, tufted, innovation-shoots intravaginal or mixed. Culms erect, 
3-18in. high, slender, glabrous, 3-noded, upper node about the middle 
of the culm. Leaves usually much shorter than the culms, 2-10 in. long, 
7z-hin. broad, linear, suddenly acuminate at the tip, flat or those of the 
innovation-shoots complicate, erect, quite glabrous, finely striate ; sheaths 
lax, compressed; ligules ovate, acuminate, often dentate. Panicle 
broadly ovate to ovate-oblong or linear-oblong, dense, nodding or more 
rarely erect, 1-4in. long; rhachis smooth, terete; branches binate or 
ternate, once or twice divided, smooth, capillary. Spikelets pale-green or 
whitish-green, much compressed, elliptic-oblong, +-41n. long, 5-6-flowered. 
Two outer glumes slightly unequal, acuminate, glabrous ; lower subulate- 
lanceolate, 1-nerved ; upper longer and broader, about 4 as long as the 
whole spikelet or rather more, lanceolate, 3-nerved. Flowering glumes 
lanceolate, acuminate, often incurved at the tip, usually 5-nerved, but the 
intermediate nerve on each side faint and sometimes obsolete, callus 
with a tuft of crisped woolly hairs more than 4 as long as the glume, 
remainder of the glume glabrous, smooth. Palea 4 shorter than the glume, 
linear-oblong, bidentate, pubescent on the keels.—Cheesem. Man. N.Z.

with violet. * Toe. t20S.35:-Saa2.

Separated without any difficulty from P. foliosa, with which it was placed by 
Hooker, by the different habit, much smaller size, shorter narrower and smoother 
leaves, smaller and proportionately broader panicle, and less prominently nerved 
flowering glumes, which are less silky at the base, and almost smooth above. 
4. P. litorosa Cheesem. Man. N.Z. Fl. (1906) 1156—A tall densely 
tufted species, often forming tussocks 2-4 ft. high. Culms many, branched 
at the base, and there closely compacted together, leafy, quite glabrous, 
2-3-noded, striate. Leaves much longer than the culms, narrow linear- 
filiform, gradually drawn out into long acuminate points, strongly invo- 
lute throughout, coriaceous, glabrous, striate, erect at the base, curving
