very slender, branches few, suberect, short. Spikelets few, shortly pedicelled, 
erect, « in. long, pale, shining. Empty glumes rigid, oblong-lanceolate, 
acuminate; flowering one hard, rather shorter, silky at the base, truncate, 4- 
toothed; awn on the middle of the back, exserted, rigid, recurved. Pale 
longer than the very silky pedicel, rigid. 
Northern Island : Titiokura, top of the Enahiue range and Lake Waikare, Colenso. 
8. A. avenoides, Hook. /., n. sp. Cxdms rigid, wiry, 8-12 in. high,

slender, smooth ; ligule short ; sheath short, smooth. Panicle very narrow, 
erect, 2-4 in. long, much contracted, branches very short, erect, few-flowered. 
Spikelets ■£— £ in. long. Empty glumes oblong-lanceolate, acuminate, rigid, 
smooth and glabrous ; flowering glume sessile, as long, hard, scabrid, 2-fid, 
silky at the base ; awn dorsal, twisted, recurved. Pale as long as the glume ; 
pedicel long, pilose. 
Middle Island: grassy downs, Kangitata river, Sinclair and Haast ; Otago, lake district. 
Hector and Buchanan. Closely allied to the Tasmanian A. montana. 
9. A. Youngii, Ilook.f., n. sp. Similar in habit to A. avenoides, but 
larger, 2-4 ft. high, more robust. Leaves flat, -g— 5- in. diam., panicle 4-6 
in. long, very slender, flexuous ; branches very short. Spikelets 5- in. long. 
Empty glumes oblong-lanceolate, acuminate, rigid, smooth, glabrous, nerve- 
less ; flowering glume as long, pedicelled, hard, scabrid, 2-4-cuspidate ; awn 
very short, almost terminal. Pale as long as the glume ; pedicel stout, with 
long silky hairs. 
Middle Island : dry hillsides, sources of the Waitaki, Haast. Allied to the Tasmanian 
A. scabra. 
10. A. quadriseta, Br ; — FI. N. Z. i. 296. Culm 6 in. to 4 ft. high, 
smooth or rough, erect, stout or slender. Leaves shorter than the culm, flat 
or involute, often setaceous, glabrous or scabrid. Panicle 2-6 in. long, slen- 
der or stout, usually extremely dense cylindric and spike-like, rarely open be- 
low and pyramidal, or interrupted and as it were lobed, pale-green, shining, 
lower branches sometimes spreading, whorled. Spikelets pedicelled, variable, 
J-— jk in. long, shining. Empty glumes lanceolate, keels scabrid ; flowering 
glume shorter, on a short bearded pedicel, coriaceous, concave, scaberulous, 
obscurely 5 -nerved; nerves usually ending in minute exserted points or awns, 
2-fid with a stout dorsal awn. Pale as long as the glume. — A. elatior, Steud. ; 
Avena quadriseta, Labill. FI. Nov. Holl. i. t. 32 ; Bromidium, Nees ; perhaps 
the Agrostis montana, Br., of Baoul, Choix, 39. 
Abundant throughout the Northern and Middle Islands, Banks and Solander, etc. 
Also very common in Australia and Tasmania. 
Aristida caaycina, Br. ; — FI . N . Z . i. 293. Culms glabrous, wiry, tufted, annual ?, 1 
ft. high. Leaves subulate. Panicle 3 in. long, very slender. Spikelets few, J in. long, 
shortly pedicelled, 1-flowered. Empty glumes of equal length, shorter than the flowering, 
which has a 3-cleft awn at its tip. 
Northern Island: Bay of Islands ?, A . Cunningham. I have seen no reputed New Zea- 
land specimen of this, but its finder’s ; it is a native of tropical Australia, and not being 
found by any other collector in New Zealand, I suspect it may have got into A. Cunning- 
ham’s herbarium by accident.
