9. D. seiurea,Hook. f. Fl. Nov. Zel. i (1853) 294.— Smaller than 
D. crinita and more slender. Culms tufted, 1-2 ft. high, slender, quite 
elabrous. Leaves chiefly at the base of the culms and much slforter than 
them, narrow, flat or convolute, sometimes almost setaceous, glabrous or 
the lower ones pubescent ; sheaths smooth ; ligules short, broad. Panicle 
3-6 in. long, much more lax and open than in D. crinita ;_branches slender, 
capillary, scabrid. Spikelets }in. long, rarely more. Two outer glumes 
equal or nearly so, long-acuminate, margins hyaline, keel smooth or scabrid ; 
3rd or flowering glume nearly as long, convolute, smooth or slightly 
scabrous, entire or 2-fid at the tip ; awn 4—#in. long, flexuous, usually but 
not invariably twisted at the base, inserted on the back of the glume close 
to the tip. Palea narrow-linear, 2-fid—Hook. f. Handb. N.Z. Hl. (1864)

20. DESCHAMPSIA Beauv. \@{?2 , 
Perennial grasses. Leaves narrow, flat or convolute. Spikelets rather 
small, 2-flowered, arranged in lax or contracted panicles; rhachilla disar- 
ticulating above the 2 outer glumes, produced between the flowering glumes 
and above the upper flower as a naked or hairy bristle, rarely ending in 
an imperfect flower. Glumes 4; 2 outer slightly unequal, persistent, empty, 
keeled, acute, membranous, shining; 3rd and 4th (or flowering glumes) 
membranous or almost hyaline, toothed at the apex; dorsal awn slender, 
twisted at the base, sometimes very small or wanting. Palea narrow, 2- 
nerved. Lodicules 2, ovate. Stamens 3. Styles distinct ; stigmas plumose. 
Grain oblong, enclosed within the unaltered flowering glume and palea. 
Species about 25, dispersed through most cold or temperate regions. One of the 
New Zealand species extends through the whole range of the genus; the remaining 6 
are endemic. These constitute a somewhat anomalous group, differing from the true 
Deschampsiae in the awn being almost terminal and very small, or altogether absent. 
They may ultimately form a separate genus.
