74 FLORA OF TASMANIA. | Restiacee. 
Gen. IV. HYPOLANA, Br. 
Flores dioici, 3 ebracteolati, squamis ament sessiles; 9 solitarii. Masc. Amenta multiflora, laxe 
paniculata. Perianthium 6-glume. Stamina 3; antheris peltatis, simplicibus. Fam. Amenta terminalia, 
uniflora. Perianthium 6-glume, brevissimum. Ovarium 1-ovulatum ; stylo deciduo, 2—3-fido. Nur ossea, 
stipitata, apice late crasse umbonata, basi perianthio brevi cincta.—Herbe ; rhizomate repente; culmis 
teretiusculis, ramosis, vaginatis; inflorescentia mascula Leptocarpi. (Character e H. fastigiata.) 
I do not know the limits of this genus; there are several species described from Swan River, and others exist 
amongst the South-western Australian plants of the Hookerian Herbarium, provisionally referred by me to Lepto- 
carpus and Restio, and requiring close examination. 1 have drawn up the generic character from the Tasmanian 
H. fastigiata alone, for the H. exsulea of Brown I take to be the female of Labillardiore's Calorophus elongatus, the 
male of which Brown has referred to Restio. The male plant of H. fastigiata very closely resembles that of Lepto- 
carpus Brownii in appearance and structure, but its eulms are ashy, more pubescent, and excessively branched. The 
female plant resembles the male in general appearance, but instead of bearing terminal effuse panicles of nodding 
or drooping eylindrical amenta, it has solitary or very few terminal, erect, single-flowered amenta.— Female flower 
sunk in the large upper scales of the amentum; perianth of six very small glumes, that embrace the base of the 
stalked nut, and adhere to it after it has fallen away. Nut one-celled, one-seeded, with a large, polished, pale, 
hemispherical or conical, umbonate top. (Derivation of name unknown to me.) 
1. Hypolsena fastigiata (Br. Prodr. 251); culmis fastigiatim ramosis teretibus striatis cineras- 
centibus, vaginis strictis brunneis apice membranaceis, perianthii fructiferi glumis ovalibus.— Kw», En. 
ii. 451. (Gunn, 599, 963, 964, 965.) (Tas. OX XXVII.) 
Has. Abundant in sandy places which are wet in winter.—(Fl. Nov.) (v.v.) 
Disrris. New South Wales, Victoria, and Swan River. 
Restio cinerascens, Br., of South-western Australia, most strongly resembles the male of H. fastigiata, if it be 
not the same plant.—PrATE CXXXVII. Fig. 1, male amentum ; 2, scale of ditto, and flower; 3, flower, removed ;

Gen. V. CALOROPHUS, Zas. 
Amenta parva, vaginis culmi semi-immersa, pauciflora. Flores monoici v. dioici. Maso. Perianthium 
6-glume. Stamina 3; antheris simplicibus, peltatis. Fam. Perianthium 6-glume, breve. Ovarium 1- 
ovulatum ; siylis 2-3. Nus ossea v. crustacea, elliptica, apice non incrassata, perianthio cincta.—Herbee Ê 
rhizomate repente; culmis gracillimis, flexuosis, subfastigiatim v. alternatim ramosis, semiteretibus ; 
ore barbatis glabrisve, appressis, coriaceis, mucrone patente terminatis; amentis parvis, 
ceis cartilagineisve. 
vaginis 
squamis rigide coria- 
Several species of this genus abound in extratropical Australia, but all want examination. 
from Hypolena in habit, in the mucronate apex to the sheaths of the culm, in the three stout, 
the absence of a tumid top of the nut.— Culms rigid, wiry, 
the branches very slender, terete, or grooved on one side. Sheaths very rigid, coriaceous, cartilaginous, closely in- 
vesting the culms, with patent, rigid, subulate points. Amenta small, unisexual, rarely hermaphrodite, more or 
less sunk in the sheaths of the culm ; scales convolute. Male of few flowers. Perianth included or exserted, of 
six lanceolate glumes, and three stamens with exserted anthers. Female amenta with one or few almost terminal 
flowers, of which the upper alone is perfect. Perianth of six small glumes, which adhere to the ripe nut. (Name 
from kaXopodos, a Restio, according to Labillardiére.) 
The genus differs 
pale styles, and in 
green, often flexuose, sparingly or profusely branched,
