Northern Island : rocky places near the sea. Bay of Islands, Cunningham ; east coast, 
Colenso, etc. Also a native of Australia, but not of Tasmania ; it is allied to the European 
B. tectorum, L. 
Of introduced species, Bromus mollis , Linn., a small species with short ovoid panicles, and 
tumid villous spikelets, and broad glumes with short awns, has been gathered in the 
Acheron valley by Travers, alt. 4000 ft. 
B. racemosus, Linn., a similar species, with glabrous spikelets, is introduced near Dnu- 
edin, Otago. 
25. TRITICUM, Linn. 
Annual tufted or perennial creeping grasses. Leaves involute or flat. — 
Spikelets spiked, usually jointed at the base, on alternate sides of an unjointed 
compressed rachis, sessile, parallel to the long axis of the rachis, 3-rnany- 
flowered. Empty glumes 2, often unequal, rigid, concave, keel often scabrid ; 
flowering ones hard and coriaceous, obtuse acute or awned, concave, keel 
ciliate. Pale 2-nerved ; nerves ciliate at the back. Scales 2, entire, often 
ciliated. Stamens 3. Ovary hairy at the top; styles distinct. Grain free, 
or adhering to the pale, hairy at the top. 
A very large European and Oriental genus, also found in most temperate countries, to which 
the cultivated Wheat belongs.

in. long. Spikelets 6-12, 8-16-flowered, ^-1|- in. long. Empty glumes 
linear-lanceolate, unequal, acuminate, nerved ; flowering ones much longer,

Northern and Middle Islands: abundant, Banks and Solander, etc. ; Cape Palliser, 
and elsewhere on the east coast and interior, Colenso ; Auckland, Sinclair. Closely allied 
to the European T. repens, but annual. 
2. T. scabrum, Br. ; — FI. N. Z. i. 311. Culms very variable, annual, 
tufted, slender, 3 in. to 3 ft. high, smooth. Leaves 1-4 in. long, flat or in- 
volute, usually scabrid on both surfaces. Spike 4-6 in. long. Spikelets 2-8 
(rarely 1), with the awns li- 2^ in. long, 6-10-flowered. Empty glumes 
lanceolate, often small, nerved, lower truncate ; flowering as in T. multijlorum, 
but the awn is 3-5 times as long as the glumes, flexuous straight or recurved.
