lets j,-tin. long, ovate, brownish-green or silvery-brown, 4-6-

glumes broadly oblong, obtuse, faintly 5-nerved, silky throughout 
with short hairs, but no tuft of crisped hairs on the callus; mar-

A pretty and distinct species, easily recognised by its small size and slender 
delicate habit, lax panicle, small silvery-brown spikelets, and faintly nerved 
silky flowering glumes. Hooker describes the flowering glumes as glabrous and 
nerveless, but I do not find them so.

394.—Culms small, densely tufted, quite smooth and glabrous, 
leafy, 2-4in. high. Leaves equalling or sometimes overtopping the 
culms, erect or slightly spreading, slender, smooth, flaccid, very 
narrow, almost setaceous, complicate when dry; sheaths rather 
lax, almost as long as the Bee grooved ; ligules short, mem- 
branous, truncate. Panicle 4—-1in. long, Tes of 3-6 spikelets on 
rather long smooth pedicels. Spikelets $-+in. long, broadly oblong, 
rather turgid, purplish-brown, 3-4- flowered. Two outer glumes 
subequal, about 4 the length of the flowering glumes immediately 
above them, oblong, obtuse, 3-nerved, quite smooth. Flowering 
glumes broadly oblong, obtuse, prominently 5-nerved, quite smooth 
and glabrous. Palea almost as long as the glume, linear-oblong, 
minutely ciliate on the keels. Anthers oblong, minute, about =, in. 
long.

I have seen very few specimens of this species, and the above description 
will probably require modification when a larger series is obtained. It appears 
to be nearest to P. exiqgua, but the panicle is much more lax, the spikelets 
larger and more turgid, and the outer glumes are much shorter. 
19. P. exigua, Hook. f. Handb. N.Z. Fl. 338.—Culms densely 
tufted, small, slender, quite smooth and glabrous, leafy, 1-din. 
high. Leaves numerous, shorter than the culms or rarely equalling 
them, 4-3 in. long, very narrow, involute, setaceous, erect, soft and 
flaccid, smooth; sheaths lax, thin, grooved; ligules short, white, 
membranous. Panicle small, +? Zin, long, rarely more, narrow, 
contracted, usually dense-flowered - branches few, short, erect. 
BEelete few or many, green tinged with purplish-red, ovate, small, 
got in. long, 2-3-flowered. Two outer glumes unequal, mem-
