outwards above; sheaths very long, smooth, shining; lgules oblong, 
membranous. Panicle 3-5in. long, erect or inclined, closely branched or 
more or less open; branchlets few or many, finely scaberulous. Spikelets 
pedicelled, compressed, ovate-oblong to ovate-lanceolate, 4-3in. long, 4-6- 
flowered. Empty glumes slightly unequal, barely $ the length of the 
spikelet, lanceolate, acute, 3-nerved, the central nerve alone excurrent. 
Flowering glumes ovate-lanceolate, acute or subacute, prominently 5-nerved, 
callus, margins, and lower part of the keel with long crisped hairs, becoming 
shorter towards the middle of the glume, the upper part of the glume 
minutely scaberulous. Palea } shorter than the glume, linear-oblong,

This, with Poa foliosa and Danthonia antarctica, constitute the chief “ tussock- 
grasses ’’ of the Subantarctic islands. I am unable to separate from it Mr. Petrie’s 
P. Poppelwellii, based on cultivated specimens originally from Herekopere Island. 
5. P. Astoni Petrie in Trans. N.Z. Inst. xxxvii (1906) 423. — Culms 
densely tufted, 12-15in. high. Leaves equalling or exceeding the culms, 
very narrow, linear-filiform, gradually narrowed into an almost pungent 
point, closely involute, striate, glabrous ; sheaths long, compressed, striate ; 
ligules broadly triangular, acute. Panicle 2—24in. long, ovate or ovate- 
oblong, rather dense ; branches short, simple or divided. Spikelets com- 
pressed, ovate-oblong, tin. long, 5-6-flowered. Two outer glumes about 
k as long as the spikelet, subequal, broadly lanceolate, acuminate, 
glabrous, 3-nerved. Flowering glumes ovate-lanceolate, acuminate, keeled, 
strongly 5-nerved, usually with a tuft of crisped hairs on the callus and 
lower part of the keel, but frequently without. Palea linear-oblong, biden- 
tate, ciliate-scabrid on the keels —Cheesem. Man. N.Z. Fl. (1906) 1165.

This is closely allied to P. litorosa, from which it is best distinguished by its 
smaller size and more slender habit, and the usually smaller spikelets. Many specimens 
are quite intermediate in their characters.

tufted, sparingly leafy, slender, strict, erect, smooth and polished, pale 
yellowish-green, 12-18in. high, perfectly glabrous, 2- or rarely 3-noded, 
the lowest node distant from the base. Leaves longer or shorter than the 
culms, erect, filiform, strongly involute so that the leaf is almost terete, 
somewhat rigid and almost pungent-pointed, perfectly smooth and glabrous, 
striate ; sheaths long, broad, membranous; ligule rather long, oblong, 
obtuse. Panicle 2—4 in. long, very narrow, linear, strict, erect ; branches
