at the tips. Spikelets 14+in. long, green or purplish. Two outer 
glumes slightly unequal, narrow-lanceolate, acuminate, 1-nerved or 
3-nerved with the lateral veins very short, scabrid on the keel and 
sides ; 3rd or flowering glume 4-4 shorter, oblong, truncate, silky at 
the base, 5-nerved, the 2 lateral nerves produced on each side into 
short awns, the 2 outer of which are longer than the 2 inner; dorsal 
awn from below the middle, straight or bent, usually exceeding the 
spikelet. Palea about 2 as long as the flowering glume, linear, 
2-nerved. Rhachilla produced into a silky bristle almost as long as 
the palea.—Hook. f. Fl. Nov. Zel.i. 298; Benth. Fl. Austral. vii.

Var. tenuis, Petrie, MS.—Smaller and much more slender. Leaves nar- 
row, involute. Panicle smaller, with fewer branches. Spikelets rather 
smaller. 
NortH anp SoutH Is~tanps, CHatHam Istanps: Abundant throughout in 
rocky or sandy places near the sea. Inland at Te Aroha, Upper Thames 
Valley. Var. tenwis: Catlin’s River, Otago, H. J. Matthews. 
Easily distinguished from D. Forsteri by the stouter habit and broader 
leaves, large spikelets, and by the more glabrous flowering glume, the lateral 
nerves of which are excurrent as short awns. It is a common Australian and 
Tasmanian plant. 
3. D. setifolia, Hook. f. Fl. Nov. Zel. i. 299, t. 658.—Culms 
tufted, slender, wiry, smooth, 4-i2in. high. Leaves shorter than 
the culms, narrow, setaceous or filiform; sheaths smooth, striate, 
the uppermost long, tight; ligules oblong, membranous. Panicle 
erect, 1-24in. long, 1-4in. broad, narrow, contracted; branches 
few, short, erect, scaberulous, sparingly divided. Spikelets few, 
pale-green, tin. long; pedicels short, scabrid. Two outer glumes 
subequal, oblong-lanceolate, acuminate, firm, spreading, keeled, 
1-3-nerved, the lateral nerves usually short, keel scabrid ; 3rd or 
flowering glume +-} shorter, hard and almost coriaceous, silky at 
the base, the hairs almost as long as the glume, truncate and 
minutely 4-toothed at the tip; awn from the middle of the back, 
stout, scabrid, recurved, longer than the spikelet. Palea almost as 
long as the flowering glume, linear-oblong, 2-nerved. Rhachilla 
produced into a siiky bristle half as long as the palea or more.—

tain districts from the East Cape and Mount Egmont southwards. 3000- 
5000 ft. 
Allied to the following species, but a much smaller plant, panicle smaller 
and more slender, spikelets not much more than half the size, and flowering 
glume much more silky at the base and broadly truncate at the tip.
