896 GRAMINE. [T'riodia. 
SoutH Is~tanpD: Nelson—Clarence Valley, 7. F. C. Canterbury—Upper 
Waimakariri and Broken River, Hnys! Kirk! Cockayne! T. F. C. Otago— 
Not uncommon in the dry plains of the central and north-western portions of 
the district, Petrie ! 500-3000 ft. 
A curious little species, with much of the habit of small states of Zoysia 
pungens. 
2. T. pumila, Hack. MSS.—Culms tufted, slender, glabrous, 
much branched at the base, 2-3 in. high. Leaves shorter than the 
culms, very narrow, involute, filiform, strict, erect, 1-2in. long; 
sheaths pale, membranous, deeply grooved, glabrous or sparingly 
pilose with long soft hairs; ligules reduced to a transverse ring 
of hairs. Panicle 4-1 in. long, strict, erect, much contracted, of 
3-15 spikelets; branches very short, erect, pubescent. Spike- 
lets 4-1 in. long, lanceolate, 2-3-flowered. Two outer glumes 
exceeding the flowering glumes, subequal, lanceolate, acute or 
subacute, 5-d-nerved. Flowering glumes broadly ovate, sparsely 
silky- -pilose on the margins and back, faintly 5-7-nerved, minutely 
3-toothed at the apex, the central tooth mueroniform. Palea bifid 
at the tip, 2-keeled, ciliolate on the keels.—Atropis pumila, Kirk in 
Trans. N.Z. Inst. xiv. (1882) 379. 
SourH Isnanp: Canterbury—Upper Waimakariri and Broken River, Kirk ! 
T. H. C.; mountains near Lake Tekapo, T. F.C. Otago—Not uncommon in 
mountainous districts, Buchanan! Petrie! Kirk! Aston! Altitudinal range 
usually from 2000 to 5000 ft., but descending to sea-level in the south of 
Otago. 
Referred to Atropis by Mr. Kirk, but clearly a Triodia, and closely allied 
to the following species, from which it differs ia the longer and narrower spike- 
lets, narrow outer glumes, and silky flowering glumes, which are distinctly 
though minutely 3-toothed at the apex. 
3. T. australis, Petrie iv Trans. N.Z. Inst. xxii. (1890) 442,.— 
Culms densely tufted, much branched at the base, erect or spread- 
ing, quite glabrous, leafy below, 2-4in. high. Leaves usually 
shorter than the culms, narrow, involute, filiform, deeply striate ; 
sheaths broad, grooved, pale; ligules reduced to a narrow band of 
short white hairs with a longer tuft on each side. Panicle small, 
strict, erect, contracted, 4-2in. long, of 6-15 spikelets ; branches 
4-6, short, pubescent. ‘Spikelets Shean ¢in. long, 2-4-flowered. 
Two outer glumes rather shorter than the flowering glumes, 
subequal, broadly ovate, obtuse, 7-nerved; margins broad, pale. 
Flowering glumes very broadly ovate or rounded, glabrous, firm, 
9-nerved, minutely and irregularly 3-toothed or erose at the tip. 
Palea broad, 2-keeled, the keels ciliolate.
