XII. GIIAMINE/E. 
[ Triselum . 
broad, oblong, acute, membranous, as long as the spikelets ; flowering glumes 
2-cuspidate, nearly glabrous, with a few short hairs at the base; awn dorsal, 
stout, recurved, exserted, inserted below the 2-cuspidate tip. 
middle Island : Macaulay valley, alt. 3-4000 ft., Uaast and Young. A very distinct spe- 
cies, closely allied to a Victorian alps one, distinguished from T. subspicatum by its slender 
tall culm, long very slender panicle, and broad outer glumes. It may, however', prove to be 
a form of that species. It is named in compliment to Mr. W. Young, Mr. Haast’s able and 
indefatigable assistant-surveyor, who paid much attention to collecting the Grasses of the 
Southern Alps. 
Avena saliva, Linn., the cultivated Oat, has been found as an escape from cultivation in 
various parts of the islands. 
20. &LYCERIA, Br. 
Erect, glabrous, often aquatic grasses. Culms tufted or creeping below. 
Leaves flat or involute. Panicle long and contracted. — Spikelets pedicelled, 
linear, glabrous, herbaceous, many-flowered. Empty glumes unequal, con- 
cave, obliquely truncate, much shorter than the spikelet ; flowering ones 
numerous, imbricated, oblong, obtuse, 7-nerved, awnless. Pale as long 
as the glume. Scales 1, or 2 and connate. Stamens 2 or 3, Grain free, 
glabrous. 
A small genus, found in temperate regions of both the north and south hemispheres, the 
grain of one species of which has been used as food during famines. 
1. G. stricta. Hook. f. FI. N. Z. i. 304. Culms slender or stout, gla- 
brous, 1-2 ft. high. Leaves glabrous, short, 2-4 in. long, involute, strict, 
almost filiform; sheath long, tumid, striate; ligule short, broad. Panicle 
very slender, 4-6 in. long ; branches unequal, strict, whorled, erect, spread- 
ing after flowering. Spikelets terete, green, ^— §• in. long, 6-14-flowered. 
Elowering glumes with obscure nerves. Scales connate, lobed at the broad 
tip. — El. Tasman, ii. 123. t. 162 B. 
Northern Island : east coast, Colenso. middle Island : Akaroa, Raoul. Also a na- 
tive of Tasmania and South-East Australia. 
21. CATABROSA, Palisot. 
Tufted, glabrous, erect grasses. — Spikelets panicled, 2-flowered, scarious, 
shining. Empty glumes 2, short, unequal, awnless, convex at the back ; 
flowering ones concave, truncate, erose, herbaceous, awnless, lower sessile, 
upper pedicelled. Pale 2-nerved. Scales 3. Stamens 3. Grain glabrous, 
free. 
A small genus of temperate climates, not hitherto found in Australia or Tasmania. 
1. C. antarctica, Hoolc.f. FI. N. Z. i. 308. t. 56. Culms decumbent, very 
slender, 6-12 in. high, branched below, leafy. Leaves involute, longer than 
the culms, slender, almost filiform ; ligule long, narrow, membranous ; sheaths 
deeply furrowed. Panicle very slender, erect, contracted, 1-2 in. long ; 
branches few, slender. Spikelets very few, small, flat, white, glistening, 
in. long. Empty glumes unequal, acute ; flowering ones convex with an ob- 
tuse jagged tip, slightly webbed at the base ; nerves obscure. Anthers 
broad, short. — FI. Antarct. i. 102. t. 56.
