rough above, often glaucous ; sheaths tight, pale, grooved; ligules 
short, truncate, membranous. Spike straight, erect, 3-6in. long, 
of 6-12 spikelets; rhachis pubescent on the angles. Spikelets 
about lin. long, close or somewhat distant, erect, appressed to the 
rhachis, 6-12-flowered. Two outer glumes small, unequal, lanceo- 
late, acuminate, 3—7-nerved. Flowering glumes oblong-lanceolate 
when spread out, convolute, smooth and rounded on the back 
below, scabridly keeled above, 7-9-nerved, coriaceous, acute or 
mucronate or produced into a short awn of varying length. Palea 
sharply keeled and folded, ciliolate on the keels.—Triticum multi- 
florum, Banks and Sol. ex Hook. f. Fl. Nov. Zel. i. 311; Handb.

Var. longisetum, Hack. WSS.—Awn longer, sometimes half the length 
of the flowering glume. 
Nort Istanp: Not uncommon in lowland districts throughout, especially 
near the coast. SoutH Isnanp: Queen Charlotte Sound, Banks and Solander ;

A variable plant in the size of the spikelets, number of flowering glumes, 
and the extent to which the awn is developed.

Culms laxly tufted, very slender, weak, decumbent at the base, 
erect above, sparingly leafy, 1-24ft. high. Leaves much shorter 
than the culms, #,—4in. broad, flat, flaccid, striate, minutely rough 
to the touch, glabrous or sparingly villous; sheaths long, tight, 
softly villous or the upper ones almost glabrous; ligules short, 
truncate, erose. Spike 2-5in. long, slender, erect or inclined, 
often interrupted below, of 9-18 spikelets; rhachis compressed, 
scabrid on the angles. Spikelets bluish-green, $in. long, 2—4- 
flowered. Two outer glumes about 4 the length of the spikelet, 
subequal, linear-lanceolate, 3—5-nerved, gradually narrowed into a 
scabrid acuminate point or awn } to 4 the length of the glume. 
Flowering glumes lanceolate, rounded on the back, smooth and 
coriaceous, 5-nerved, sometimes minutely 2-toothed at the tip, 
narrowed into a short scabrid awn about + the length of the 
glume. Palea shorter than the glume, linear-oblong, coriaceous, 
ciliolate on the keels.—Asprella aristata, Petrie in Trans. N.Z.

A very distinct species, at once recognised by the weak habit, flat mem- 
branous leaves, narrow spike, and few-flowered spikelets. Very similar in habit 
to Asperella gracilis, and easily mistaken for it on a cursory inspection, but 
the structure of the spikelet is that of Agropyrum.
