2. A. aristatum Cheesem. Ill. N.Z. Fl. ii (1914) t.. 234. — Culms 
laxly tufted, very slender, weak, decumbent at the base, erect above, 
sparingly leafy, 1-2} ft. high. Leaves much shorter than the culms, 
tin. 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, 
9-4-flowered. Two outer glumes about $ the length of the spikelet, subequal, 
linear-lanceolate, 3-5-nerved, gradually narrowed into a scabrid acuminate 
point or awn 4-4 the length of the glume. Flowering glumes lanceolate, 
rounded on the back, smooth and coriaceous, 5-nerved, sometimes minutely 
9-toothed at the tip, narrowed into a short scabrid awn about 4 the length 
of the glume. Palea shorter than the glume, linear-oblong, coriaceous, 
ciliolate on the keels.—A. Enysii 7. Kirk in Trans. N.Z. Inst. xxvii (1895) |

A very distinct species, at once recognized by the weak habit, flat membranous 
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.

3. A. seabrum Beauv. Agrost. (1812) 102.— Annual or perennial, very 
variable. Culms faxly tufted, slender, decumbent at the base, erect or 
ascending above, quite smooth, leafy, 6-24in. high. Leaves 2-9 in. long, 
so-45 in. broad, flat or convolute, usually scabrid on both surtaces, often 
elaucous ; sheaths smooth, grooved, the upper long ; ligules short, truncate. 
Spike 3-9 in. long, of 2-10 rather distant erect spikelets ; rhachis flattened, 
scabrid on the angles. Spikelets 3-lin. long without the awns, 1}-31n. 
with them, 6—12-flowered. Two outer glumes small, not reaching more 
than 4 up the flowering glumes immediately above them, subequal, narrow- 
lanceolate, tapering into short acuminate points, rigid, 3-5-nerved. Flower- 
ing glumes lanceolate, coriaceous, smooth and rounded on the back at the 
base, obscurely keeled and scabrid above, 3-5-nerved, narrowed into a long 
and slender straight or flexuous scabrid awn from 3 to 5 times as long as the 
glume itself. Palea almost as long as the glume, linear-oblong, ciliolate 
on the keels —Benth. Fl. Austral. vii (1878) 665; Cheesem. Man. N.Z.
