Deyeuxia. | GRAMINEAE. 161 
Var. tenuis Petrie MS.—Smaller and much more slender. Leaves narrow, 
involute. Panicle smaller, with fewer branches. Spikelets rather smaller, 
NortH AND Soutu Istanps, CHaTHAM IsLaANDS, STEWART IsLAND: Abundant 
throughout in rocky or sandy places near the sea. Inland at Te Aroha, Upper Thames 
Valley. Var. tenuis: Catlin’s River, Otago, H. J. Maithews. 
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. 
4, D. setifclia Hook. f. Fl. Nov. Zel. i (1853) 299, t. 6583.—Culms \” 
tufted, slender, wiry, smooth, 4-12in. high. Leaves shorter than the 
culms, narrow, setaceous or filiform; sheaths smooth, striate, the upper- 
most long, tight; ligules oblong, membranous. fPanicle erect, 1—-241n. 
long, $-4in. broad, narrow, contracted; branches few, short, erect, 
scaberulous, sparingly divided. Spikelets few, pale-green, {in. 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 4-4 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 silky bristle $ as long as the palea or more.—Buch. N.Z. Grasses

common in mountain districts from the East Cape and Mount Egmont southwards. ° 
3000-5000 ft. 
Allied to the preceding 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. 
5. D. avenoides ,Buch. N.Z. Grasses (1880) AEE ga tufted, erect, 
slender, rigid, smooth, 9-24in. high. Leaves much shorter than 
the culms, narrow, in slender forms almost filiform, smooth, strongly 
involute ; sheaths smooth, deeply grooved, the uppermost long; ligules 
short, broad. Panicle erect, 2-5in. long, }-4in. broad, narrow, con- 
tracted, usually dense ; branches short, erect, sparingly divided. Spikelets 
pale-green, #-+in. long; pedicels shorter than the spikelets. Two outer 
glumes subequal, lanceolate, acuminate, sharply keeled, rigid, 1- or rarely 
3-nerved, keel scabrid, sides smooth or minutely rough; 38rd or flowering 
glume slightly shorter, hard, convolute, scabrid, slightly silky at the base, 
minutely 2-4-cuspidate; awn from below the middle, stout, recurved, 
twisted below the bend, longer than the spikelct. Palea almost as long 
as the flowering glume, linear, hyaline, 2-nerved. Rhachilla produced 
into a silky bristle nearly 4 as long as the palea.—Cheesem. Man. N.Z. FI.
