Plant perennial, erect, growing in large bushy tufts. Culms 12-18 inches 
high, stout, smooth. Leaves numerous, shorter than the culms, 10-14 
inches long, 2 lines broad, flat, membranous, many nerved, keeled, slightly 
scaberulous, more so at tips which are obtuse.  Spikelet 3-44 inches long, 
ith of an inch broad, trigonous; upper 6-12 lines male; bracts 2 sometimes 
8, very long, longest and lowermost 6-10 inches and more, foliaceous, very 
narrow, channelled, scaberulous above, slightly so below; glumes closely 
imbrieate, linear, acute, 2 lines long, glabrous, obscurely nerved, keeled, 
dark-brown ; utricle shorter than glume, subrhomboidal, glabrous, nerved, 
subtriquetrous, compressed, dark-brown at top light-coloured below ; bristle 
slender, as long as the utricle. 
Hab. Woods, dry hills, between Norsewood and Danneverke, Waipawa 
County, 1882-3: W.C. 
Obs.—A species having affinity with U. australis; from its much softer 
foliage often browsed on by cattle. 
Uncinia obtusata, sp. nov. 
Plant thickly cespitose in rather small tufts, Culms 12-21 inches high, 
sub-erect, rigid, smooth, but finely scaberulous at top for about 1 inch 
below spikelet, triquetrous. Leaves much shorter than culms, 6-9 inches 
long, linear, 1th of an inch wide, flat, membranaceous, grassy, sub-erect, 
smooth, finely and closely scabrous towards top, obtuse, nerved, slightly 
keeled. Spikelet 1-14 inches long, loose, spreading, few-flowered, flowers 
distant ; upper 4-5 lines male, very slender; bract 3-4 inches long, filiform, 
obtuse, scabrous, and densely so at top ; glumes closely imbricating, shorter 
than utricle, 14 lines long, deltoid-acuminate ; 1-nerved, obtuse, lowest 
(one or two) trifid and awned, awn long barbed obtuse ; utricle longer than
