branches suberect, much divided, slender, glabrous, multi-spiculate. Spike- 
‘lets shortly pedicelled, much compressed, rather large, }-4in. long, 3-5- 
flowered. Two outer glumes slightly unequal, keeled, acuminate; the 
lower subulate-lanceolate, 1-nerved ; the upper broader and larger, about 
2 the length of the whole spikelet, lanceolate, 3-nerved. Flowering glumes 
ovate-lanceolate, acuminate, incurved at the tip, prominently 5-nerved ; 
callus, together with the back and margins for 4 their length, clothed 
with crisped silky. hairs; upper portion of the glume scabrid. Palea 4

Var. Tennantiana / Cheesen.—Smaller in all its parts. Culms densely tufted, 
1-2 ft. high, }-}in. ‘diam. at the base. Panicle smaller, 3-6in, long. Spikelets 
Zin. long, 2-4-flowered.—P. Tennantiana Petrie in Subantarct. Ls, N.Z. 11 (1909) 476. 
Barely differs from P. foliosa except in the reduced s'ze and fewer-flowered spikelets. 
Easily distinguished from all other New Zealand species by the great size, very 
broad fiat leaves, and large dense panicle. It is closely allied to the Kerguelen Island 
P. Cookii Hook. f., and to the well-known tussock-grass of the Falkland Islands and 
Fuegia, P. flabellata Hook. £. (Dactylis caespitosa Forst.). The flowers seem to be 
partly if not altogether unisexual, most of the specimens that I have seen being temates 
with the anthers much reduced in size.

Perennial, densely tufted, 5-20in. high. Culms shorter than the leaves, 
erect, stout, sometimes din. diam. below, compressed, leafy almost 
up to the base of the panicle. Leaves numerous, subdistichous, lower 
much reduced in size and sheathing the culm, gradually passing into the 
upper, which usually far overtop the panicle, }-1in. diam. at the base, 
from thence gradually tapering into a long acuminate point, flat, coriaceous, 
many-striate, smooth and glabrous, not scabrid; ligules large, broad, 
ovate, membranous, deeply and irregularly laciniate; sheaths long, com- 
pressed, thin and rather membranous, regularly striate. Panicie linear- 
oblong or linear-obovate ; sometimes almost clavate, dense and contracted, 
rarely sublobed towards the base, 2-34in. long, }-2in. broad, usually 
strict and erect ; branches close-set, rarely more than 14 in. long. Spikelets 
rather large, compressed, 2-3in. long, 2-4-flowered ; lower flower almost 
sessile, upper pedicelled. Outer glumes unequal, but not remarkably so, 
ovate-lanceolate, acuminate, 3-nerved; flowering glumes lanceolate or 
ovate-lanceolate, acuminate or almost awned, incurved at the tip, keeled, 
5-nerved, scabrid on the keel and nerves, shortly hairy on the sides 
towards the base, but not webbed with cottony hairs. Palea linear- 
oblong, bifid at the tip, ciliate on the margins and keel, about shorter 
than the glume. Lodicules broad-ovate, acute. Anthers large, narrow- 
linear, about j,in. long—Cheesem. Man. N.Z. Fl. (1906) 1156; Petrie
