Buchanan. Common in Tasmauia and Australia, and very near A. canina, from which it 
is best distinguished by the very lax panicle and smaller spikelets. Nearly allied to the 
European A. alpina, but with a dorsal, never basal awn. 
4. A. temula, Br. — Deyeuxia Forsteri, Kunth ;- — FI. N. Z. i. 298. A 
very elegant, glabrous, slender grass. Culms tufted, very slender, 6-24 in. 
high. Leaves very narrow, involute, often setaceous, rarely flat ; sheaths 
glabrous ; ligule narrow, oblong. Panicle large, open, spreading ; branches 
whorled, capillary, 3-6 in. long, usually 3-chotomously branched ; rachis 
often flexuous. Spikelets j 0 ~l in. long, on very slender pedicels. Empty 
glumes equal, lanceolate, long-acuminate, smooth, keel scabri-d ; flowering 
one membranous, shorter by about one-third, sessile, truncate, silky with 
scattered long hairs, and bearded at the base ; awn from the back about the 
middle, very slender, exserted. Pale 0 or small, without a pedicel at its base 
or with a very minute one. — A. Forsteri , Koem. and Schultes ; A. Lyallii , 
FI. N. Z. i. 297 ; A. leplostachys, FI. Antarct. i. 94 ; Lacknagrostis Forsteri , 
Trinius ; L. cemula, Nees ; Deyeuxia cemula, Kunth ; Arena Jiliformis, Forst. 
Throughout the Northern and Middle Islands, abundant. Banks and Solander. 
Campbell’s Island, J. D. H. Equally common in temperate Australia and Tasmania. 
I find the pedicel at the base of the pale to be so often absent, and when present so minute, 
that I am obliged to remove (his plant from the section or genus of Deyeuxia , and to unite 
with it my A. Lyallii and A. leptostachya ; the latter (from Campbell’s Island), however, 
has unusually large spikelets. 
5. A. pilosa, A. Rich. Flor. i. 134. t. 23 FI. N. Z. i. 297. Quite 
similar to A. cemula, except in being more coarse and robust, with large flat 
leaves, sometimes \ in. broad, which are described by Richard as pilose and 
scabrid, but are only scaberulous in my specimens. 
Northern Island : mountainous districts of the interior, Colenso. Middle Island : 
Astrolabe Harbour, D’Urville ; Southern Alps, Sinclair, Haast, etc.; Otago, lake district, 
Hector and Buchanan. Perhaps only a large form of A. cemula, with which it entirely 
agrees in inflorescence and all floral characters ; hut is a different-looking and far more 
robust plant. 
6. A. Billardierij Br. — Deyeuxia Billardieri, Kunth ; FI. N. Z. ii. 298. 
Culms tufted, erect, leafy, 1-2 ft. high. Leaves 6 in. long, in. broad, flat, 
glabrous or scaberulous; ligule short, oblong. Panicle very lax, 4-10 in. 
long, effuse, scabrid ; branches veiy long, whorled, capillary, 3-chotomous. 
Spikelets -g—j in. long, on very slender pedicels, green or purplish. Empty 
glumes lanceolate, acuminate, keel scabrid, sides glabrous or scabrid ; flower- 
ing glume i shorter, truncate, silky at the base, 4-nerved, the lateral nerves 
produced into short awns ; awn on the middle of the back, bent, half to twice 
as long as the glume. Pale as long as the glume, longer than the silky pedi- 
cel at its back. — A. vaginata, Steudel; Lachnagrostis Billardieri, Trinius ; 
Arena jiliformis, Labiil. FI. Nov. Holl. i. 24. t. 31, not Forster. 
Northern Island, Banks and Solander, abundant in some places, but apt to be con- 
founded with large states of A. Forsteri. Also an abundant Southern Australian and Tas- 
manian grass. 
7. A. setifolia. Hook. f. — Deyeuxia set folia, FI. N. Z. i. 299. t. 65 B. 
Culms erect, tufted, very slender, wiry, smooth, 6-8 in. high. Leaves very 
narrow, setaceous or filiform, involute, shorter than the culms, quite smooth;
