274 FLORA OF NEW ZEALAND. [Oyperacee. 
Scales distichous, acute, keeled, chesnut-brown, green at the back, three- or four-flowered. .Bristles six, long, slender. 
Nut pale brown, shining, striated with long impressed dots.—Closely allied to the South Chilian C. antarctica (Fl. 
Antarct. p. 361. t. 147), but the leaves are much shorter. 
4. Cheetospora imberbis, Br.; glaberrima, culmis fasciculatis foliosis, foliis subflaccidis lineari-setaceis 
suleatis superne canaliculatis brevioribus, spiculis parvis 1-2-floris castaneis in capitula bracteata dense 
congestis sessilibus, bracteis foliaceis elongatis, squamis distichis acutis enerviis infimis arista scaberula, 
setis 6.— Br. Prodr. 
Has. Northern Island. East Coast, Colenso. 
A. span high, tufted, leafy, quite glabrous, more flaccid than its congeners, resembling a small Juncus. Leaves 
numerous, linear-subulate, acute, channelled above, back’ striated, longer than the leafy culms. Spikelets small, 
1 line long, black or chesnut-brown, one- or two-flowered, densely clustered into one or two bracteate heads; some- 
times one cluster is on a long pedicel. Scales few, distichous, with white margins; upper acute, glabrous; lower 
with hispid, long points. Bristles six, slender. Nut not ripe.—A native of Australia and Tasmania. 
5. Cheetospora awillaris, Br.; pusilla, culmis ceespitosis procumbentibus rarius ascendentibus com- 
pressis radicantibus ramosis, ramis prostratis distiche foliosis, foliis patentibus anguste lineari-subulatis 
obtusis, spiculis solitariis binisve axillaribus et terminalibus breve pedicellatis sessilibusve paucifloris, 
squamis subdistiche imbricatis 2 supremis fertilibus, setis 6 ovario longioribus, nuce late ovata pallida 
subacuta trigona vix punctata. —Br. Prodr. (Tas. LXII. 4.) 
Has. Northern Island. Abundant in wet places, 4. Cunningham, ete. 
A small, green, leafy, tufted, flaccid plant; also found in Australia. Culms 1-4 inches long, generally creeping, 
branched. Leaves very narrow, linear setaceous, blunt, green, spreading. Spikes solitary or rarely two together, 1-2 
lines long, axillary, on short peduncles, Scales few, pale, distichously imbricated, keeled, subacute, green, with 
green backs, one or two upper fertile. Bristles three, longer than the ovary. Stamens three. Style triid. Nut 
small, white, smooth and polished, three-angled, sharp-pointed, broadly obovate.— Very dissimilar in habit to its 
congeners, and closely resembling Isolepis fluitans of Europe, in habit and the compressed branched stem, but 
differing in the more foliaceous habit, axillary spikes, trigonous nut, three stigmas and bristles. —PLATE LXII. 4.

6. Chzetospora concinna, Hook. fil.; pusilla, ceespitosa, culmis brevibus striatis basi foliatis, foliis 
setaceis, spicula solitaria terminali v. laterali castanea 2-3-flore, squamis undique imbricatis convolutis

fastigiatis brevibus dense barbato. (Tas. LXII. B.) 
Has. Northern Island. East Coast and base of Tongariro, Colenso. 
A very small, Heocharis-like plant. Roots tufted, creeping. Culms erect, setaceous, leafy below, 1-2 inches 
high, slender. Leaves shorter than the culms, setaceous, with chesnut-brown sheaths. Spikelet cylindrical, ovate, 
solitary, shining, brown, 2 lines long, lateral or terminal when the lower scale forms the apex of the culm, and is 
setaceous. Scales rolled round one another on all sides, blunt, two- or three-flowered. Stamens and Styles three. 
Nut pale brown, trigonous, turgid, scabrous or glabrous, surrounded at the base with a dense brush of short inarti- 
culate bristles, besides the scabrous scales.—Allied to C. nitens, but the spikelets are nearly solitary; scales more 
convolute and blunter, and the hypogynous bristles quite different—Puiare LXII. B. Fig. 1, spikelet; 2, the 
same, with the lower scales removed; 3, nut; 4, hairs from its base :—all magnified.
