Pe we Ons. Var. elata| Petri in Trans. N.Z. Inst. xlv (1913) 274— Much taller and stouter 
| than the type, 18-20 in. high, forming dense tussocks. Panicles larger, reddish when 
young. 
Sourn Istanp: Canterbury — Candlestick Range, Cockayne ! Westland—Kelly’s 
Hill, Petrie!  3500-4500ft. Var. elata: Sealey Range, Hooker Valley, 4000-5000 it., 
Petrie! T. F.C. 
Allied to D. australis, but much less rigid and not so densely tufted, with broader 
flatter leaves; the panicle-branches are nearly glabrous and the spikelets smaller and 
paler; the terminal lobes of the flowering glume are broader and not awned; and the 
central awn is shorter and not twisted at the base. It is still nearer to D. planifolia. 
9. D. planifolia Petrie in Trans. N.Z. Inst. xxxiii (1901) 328.—Culms 
apparently not tufted, sparingly branched at the base, erect, slender, 
glabrous, 9-14in. high. Leaves chiefly at the base of the culms and much 
shorter than them, 2—5in. long, 3,-}in. broad, gradually tapering to an 
acute point, flat, smooth, striate; sheaths rather lax, pale, grooved, the 
uppermost much longer than the blade ; ligules a transverse band of long 
soft hairs. Panicle short, lax, ovate, 14-2in. long, of 6-12 spikelets ; 
branches few, slender, silky with long hairs. Spikelets rather large, about 
lin. long, pale-green tinged with purple, 3-5-flowered. Two outer glumes 
subequal, lanceolate, acuminate, membranous, 3-5-nerved, about as long 
as the spikelet. Flowering glumes densely silky at the base, and with long 
silky hairs along the margins and back for 4 their length, deeply 2-fid 
at the apex, the lobes acute or acuminate, but scarcely awned, 7—9-nerved ; 
intermediate awn from between the lobes, }-3 in. long, more or less flattened 
and twisted at the base. Palea linear-oblong, deeply bifid, 2-nerved, nerves 
ciliate.—Cheesem. Man. N.Z. Fl. (1906) 889. 
South Istanp: Otago—Clinton Saddle, to the west of Lake Te Anau, Peérie / 
2500 ft. 
This only differs from D. oreophila in the flatter and more membranous leaves, 
larger spikelets with longer empty glumes, and longer awn usually twisted at the base. 
I have seen few specimens, and these all from one locality. It is not improbable that 
further investigations may reduce the plant to a variety of D. oreophila. 
) 10. D. pilosa R. Br. Prodr. (1810) 177.—Culms tufted, slender, glabrous 
or sparingly pilose, leafy at the base, 1-2 ft. high, rarely more. Leaves 
usually much shorter than the culms, narrow, often setaceous, involute or 
rarely flat, glabrous or pilose with spreading hairs ; sheaths narrow, grooved, 
pilose or glabrous ; ligules reduced to a transverse band of long soft hairs. 
Panicle 1-4 in. long, usually narrow and contracted, sometimes racemiform ; 4 
branches short, erect. Spikelets about din. long, 4-8-flowered. Two 
outer glumes exceeding the flowering glumes, subequal, lanceolate, acute, 
membranous, 7-nerved. Flowering glumes 7-9-nerved, deeply 2-lobed at the 
tip, the Icbes produced into fine awns as long or longer than the glume, 
central awn from between the lobes, exserted beyond the spikelet, flattened 
and spirally twisted and often dark-coloured at the base, a tuft of silky hairs 
at the base of the callus or pedicel ofthe glume, a tuft on the margin on 
each side above the callus, sti nected by hairs on the back, and 
another marginal tuft on each side opposite to the base of the lobes, the 
sides and back between usually glabrous. Palea broad, obtuse or shortly 
bifid at the tip—Hook. f. Fl. Nov. Zel. i (1853) 303; Fl. Tasm. ii (1860) 
120; Benth. Fl. Austral. vii (1878) 594; Buch. N.Z. Grasses (1879) t. 33 ; 
Cheesem. Man. N.Z. Fl. (1906) 890. D. semiannularis var. pilosa Hook. f. 
Handb. N.Z. Fl. (1864) 333. D. nervosa Col. in Trans. N.Z. Inst. xxviii 
(1896) 612 (not of Hook. f.).
