78 FLORA OF TASMANIA. [ Cyperacee. 
Has. Marshy ground, in subalpine situations: Marlborough, Gunn.— (Fl. Jan.) 
Very similar to 4. monogynum, but with more aristate spathes, four flowers, and six to eight ovaries, imbri- 
cating in two series. 
9. Alepyrum Muelleri (Hook. fil.) ; foliis capillaribus, spatha inferiore aristata superiore mutica, 
floribus 4, gluma 0, ovariis sub-10.—Desvauxia glabra, Mueller, in Herb. Hook. (Gunn, 2015.) 
Has. Bottom of a lagoon, Macquarrie River, Gunn.— (Fl. Nov.) 
Distri. Mount Emu Creek, Victoria, Mueller ; South-west Australia, Drummond. 
Laxly tufted, scarcely an inch high. Stem excessively short, with short, white, tufted roots. Leaves rather 
flaccid, between subulate and capillary, rather shorter or longer than the scapes. Spathes about 4 inch long, the 
lower with a straight awn. Ovaries imbricated in two series; the styles more or less combined in Victoria speci- 
mens, more free in Tasmanian. 
4. Alepyrum polygynum (Br. Prodr. 253); foliis setaceis culmis rigidis brevioribus, spathis co- 
riaceis inferiore longe rigide foliaceo-aristata, floribus 1-2, gluma 0, ovariis 10-20.—Kunth, En. iii. 488 ; 
Nees, in Plant. Preiss. ii. 71. (Gunn, 1436.) 
Has. Near Georgetown, Gunn.—(Fl. Oct.) 
Disrris. Swan River and Victoria. 
Remarkable for its profusion of rigid culms, 1-3 inches high, with very short, subulate leaves at the base, 
brown, lanceolate spathes, the outer with a long, nearly straight or curved, green, foliaceous arista, $ inch long. 
Flowers one or two, with ten ovaries, 
Genus Restiaceis affine ?—TRITHURLIA, Hook. fil. 
Capitulum. solitarium, terminale, multiflorum, foliolis 4 involucratum. Flores unisexuales, capitulo 
sine ordine aggregati, omnino achlamydei. Masc. Stamen solitarium ; filamento elongato ; anthera lineari- 
oblonga, 2-loculari, basi affixa; po//ine globoso. Fam. Ovarium pedicellatum, obovatum, membranaceum, 
triquetrum, 1-loculare ` ovu/o solitario, pendulo, anatropo; siylis 2-3 filiformibus. Capsula membranacea, 
obovata, triquetra, 3-valvis ; valvis a septis intervalvaribus secernentibus. Semen lineari-oblongum, cylin- 
draceum ; testa membranacea ; raphe cellulosa ; albumine dense carnoso ; embryone minimo, conico, extre- 
mitati radiculari albuminis applicato.—Herba perpusilla, annua, aquatica; radicibus fibrosis; foliis subu- 
latis, subcellulosis ; scapis plurimis, Joliis longioribus v. brevioribus ; capitulo ¿-2 une. Jato; involucri 
foliolis ovato-oblongis, obtusis, 2 exterioribus paulo majoribus ; floribus minimis, receptaculo parvo confertis, 
JFemineis maturis a pedicello persistente solutis. 
A singular little plant, of very obscure affinity, discovered by Gunn in Tasmania, and also by 
eastern Australia, who has proposed for it the manuscript name of Juncella Tasman 
lepidee, from which however it differs remarkably in the dehiscence of the capsule, 
inserted by its base on the filament. 1 have ventured to supersede the name proposed (without description) by 
Mueller, both because the plant has no affinity with or resemblance to Juncus, and because it is not confined to 
Tasmania. In habit and the involucre it resembles Eriocaulon, but it differs fr 
om that genus in the capsule, naked 
flowers, and anther.—A minute water-plant, 1-2 inches high, growing at the bottom of fresh-water pools, and 
conspicuous (according to Gunn) when in fruit, from the bright-red colour of the minute capitula.—Roots fibrous. 
Stem. almost none, the subulate, membranous, spreading leaves appearing to rise from the roots. Scapes numerous, 
bearing a very small capitulum of minute flowers, enclosed in an involucre of four ovate-oblong, blunt, membra- 
nous leaves. Male flowers: solitary stamina with long filaments and two-celled anthers, scattered indiscriminately 
amongst the female flowers, which consist of minute, trigonous, obovate, stipitate ovaries, with two or three filiform 
Mueller in South- 
ica, and placed it in Centro- 
and two-celled anther, which is
