104 FLORA OF TASMANIA. | Graminee. 
1. Tetrarrhena distichophylla (Br. Prodr. 210); rigida, scaberula et pilosa, culmis basi ramosis 
cespitosis foliosis, foliis distichis brevibus strictis planis concavisve vaginisgue sulcatis ore ciliatis, spiculis 
scabris pilosis laxe imbricatis inferioribus pedicellatis, paleis nervosis, floris infimi hermaphrodito multo 
breviore.—Ehrharta distichophylla, Zab. Nov. Holt. i. 90. t. 117. (Gunn, 1473.) 
Haz. Dry woods, probably common: Hobarton and Penquite, @unn.—(Fl. Nov.) 
A very harsh, rigid, tufted Grass, a span to a foot high, variable in size, very rough to the touch, also covered 
with short, spreading hairs.—Oulms ascending, of many short branches, and a few long flowering ones, some of 
them prostrate, and covered with sheaths. Leaves more or less closely imbricated, distichous, strict and rigid, flat 
or concave, deeply grooved; sheaths hairy at the mouth; blade 4-14 inch long. Flowering culm leafy to the top. 
Spike 4-2 inches long, erect; lower spikelets pedicelled. Spikelets scabrid and pubescent, blunt, $ inch long. 
Glumes and lower palea short, broad, blunt. 
2. Tetrarrhena tenacissima (Nees, in Hook. Lond. Journ. Bot. ii. 409) ; scabrida, culmis elon- 
gatis flexuosis intertextis laxe foliosis ad nodos ramosis, foliis planis, vaginis ore ciliatis, culmis floriferis gra- 
cilibus, spiculis glabris, glumis obtusis nervosis, paleis obtusis inferiore ceteris 4 breviore.—T. contexta, 
Mueller, MSS. (Gunn, 987.) (Tas. CLIV.) 
Has. Moist places, near the sea, at Black River (north-west coast), Gunn. 
Distris. Victoria, Cape Otway, south-east coast of Australia. 
A very remarkable Grass, climbing over bushes with its flexuous, branching culms, 6-7 feet long.— Whole 
plant very scabrid. Culms deeply furrowed. Leaves remote, with long sheaths, hairy at the mouth and blades, 
1-13 inch long. Spikes 1 inch long, of eight to ten distichous, smooth spikelets on a flexuous rachis, terminating 
the slender upper part of the culm. ` GZumes blunt, nerved; lower palea blunt, itself as long as the upper, which 
are also blunt, and 2 lines long.—PrATE CLIV. Fig. 1, spikelet ; 2, hermaphrodite flower; 3, ovary and squa- 
mule :—all magnified. 
3. Tetrarrhena acuminata (Br. Prodr. 210); culmis decumbentibus, foliis brevibus vaginisque 
glabris, spica oblonga 4-8, spiculis lanceolatis, palea inferiore nervosa acuminata, superiore breviore trun- 
cata. 
Has. Tasmania, Brown; Longford, Archer.—(Fl. Nov.) 
Distr. Victoria. 
A slender, much branched species.—Culms decumbent, about 6-12 inches high. Leaves short, 1-3 inches 
long, glabrous. Spike oblong, of four to eight large, lanceolate spikelets. Palea strongly striate; outer acumi- 
nate; inner shorter, truncate. . 
Gen. II. MICROLANA, Br. 
Glume minime, 3-flore, floribus remote ; floribus approximatis, stipitatis, stipite barbato, inferioribus 
neutris 1-paleatis, paleis aristatis, terminali hermaphrodito. F7. hermaph.:—Palez 2; inferiore carinata, 
acuminata v. aristata ; superiore breviore, lineari, hyalina. Sguamule 2, glabre. Stamina 4. Ovarium 
sessile. Caryopsis libera, paleis obtecta.—Culmis simplicibus v. ramosis; foliis parvis v. elongatis, planis ; 
spiculis racemosis v. paniculatis. 
A small genus of Australian, Tasmanian, and New Zealand Grasses, closely allied to Tetrarrhena, differing 
from it in the long villous pedicel to the florets, which are thus separated from the small glumes, as also by the 
narrow awned palea of one or both of the neuter flowers, the linear, hyaline, upper palea of the terminal flower, and 
the linear, compressed caryopsis; the stamens are four. (Name from puxpos, small, and xAaıva, a covering; in 
allusion to the small glumes.)
