Very closely allied to A. Dyer, and mainly distinguished by its much smaller size, 
narrower panicle, and different habit. The stems are generally I-noded, whereas they 
are usually 2-3-noded in A. Dyeri. I agree with Mr. Petrie in considering that it is 
identical with Hooker’s A. subulata, originally described from immature specimens 
collected on Campbell Island. 
4, A. pallescens Cheesem. in Trans. N.Z. Inst. lin (1921) 423.—Annual, 
densely tufted and often forming a close sward, pale straw-coloured. 
Culms 3-6in. high, slender, smooth, erect, 3-noded, the uppermost node 
high up the culm. Leaves numerous towards the base of the culms and 
shorter than them, very narrow, almost filiform, smooth or very minutely 
scabrid, erect or somewhat spreading; sheaths long, deeply grooved ; 
lioule thin, scarious. Panicle narrow, but not so much so as A. subulata, 
lanceolate or ovate-lanceolate, 3-lin. !ong, straw-coloured; branches 
in fascicles of 2-4, unequal in length, somewhat spreading, finely scabrid. 
Spikelets 7-75 in. long. Two outer glumes slightly unequal, oblong-lanceo- 
late, subacute, membranous, seabrid on the keel; margins thin; 38rd or 
flowering olume about 4 shorter, thin and membranous,. hyahne, truncate, 
faintly 5-nerved ; awn wanting. Palea wanting. Grain oblong.—A. Muelleri

Near to A. subulata, but amply distinct in its 3-noded culms, the upper node of 
which is sometimes situated quite 4 of the way up the culm, in the straw-coloured 
spikelets, and in the broader and more open panicles. In A. subulata the culms are 
seldom more than l-noded, the node being placed near the base of the culm, the 
panicles are narrow and spike-like, and usually purplish in colour. In addition to 
the above, A. subulata is aL! y nd on the steep rocky slopes of mountains, never 
in swamps. VC reqqupn) S2 
5. A. Dyeri Petrie in Trans. N.Z. Inst. xxii (1890) 441.—Perennial ; 
innovation-shoots intravaginal, not clothed at the base with leafless scales, 
Culms tufted, 4-18in. high, slender, erect or geniculate at the base, 
glabrous, 2—3-noded, the Was node considerably below the culm. Leaves 
shorter than the gules, 3 tz-3 # in. broad, flat or convolute when dry, striate, 
scaberulous on the margins and hoth surfaces; sheaths terete, grooved, 
glabrous, the upper long; ligules oblong, obtuse, membranous, lacerate. 
Panicle elongated, usually from 2 to 5 in. long, but shorter in depauperated 
forms, erect, usually more or less contracted, rarely open, green or 
brownish-oreen ; rhachis slender, scaberulous above; branches in rather
