1. H. lateriflora (flowers lateral), Benth. Fl. Austr. vii. 238. Stems 

 slender, very much branched and flexuose, sometimes nearly erect and under 1ft., 

 sometimes climbing to a height of 4 or 5ft. Sheathing scales closely appressed, 

 the upper ones as well as the floral bracts or sometimes nearly all with short 

 subulate reflexed tips or filiform laminte. Mala spikelets usually 2 together 

 within the distant floral bracts along the branches, one sessile, the other shortly 

 pedicellate, few-flowered, with 1 or rarely 2 empty glumes. Glumes thin, acute 

 or acuminate, often slightly woolly-ciliate. Perianth-segments 6, narrow, nearly 

 equal, the outer ones more acute than the inner. No rudiment of the ovary. 

 Female spikelets 2 to 3 lines long, solitary within the 1, 2 or rarely 3 uppermost 

 bracts. Glumes few, lanceolate, acutely acuminate, rigid, about 1^ line long. 

 Perianth of 6 or 4 broadly ovate very thin and hyaline segments, the inner ones 

 scarcely longer than the ovary, the outer gradually rather larger. Styles 3 or 2, 

 distinct from the base. Nut ovoid-globular, sessile on a thick receptacle. —

2. H. fastigiata (erect), E. Br. Prod. 251 ; Benth. Fl. Austr. vii. 239. 

 Stems much-branched, rather slender, erect or ascending and flexuose, from 

 under 1ft. to near 2ft. high, glabrous or with a short loose white tomentum 

 especially in the inflorescence. Sheathing scales dark-coloured, appressed, 

 mostly with a short erect point. Male spikelets all pedicellate in a terminal 

 panicle, oblong-linear or at length narrow-ovate, about 3 lines long or rather 

 more when fully out. Glumes of a rich brown, rather broad with a short point, 

 a few lower ones empty. Perianth-segments 6, 2 outer ones complicate and 

 acutely keeled, the third lanceolate flat and rather acute, the 3 inner rather 

 shorter and more obtuse. Anthers almost ssessile, dorsally attached "very near 

 the base to the very short filament. Female spikelets solitary and terminal or 

 rarely 2 or 3 clustered together, 2 to 3 lines long. Glumes much more acuminate 

 than in the males. Perianth-segments 6, thinly scarious, very broad and only 

 about as long as the ovary. Styles shortly connate at the base. Nut hard, 

 sessile on a thickened receptacle. — Hook. f. Fl. Tasm. ii. 74, t. 137 ; F. v. M.

Order CLII. CYPERACEJE. 



Flowers hermaphrodite or unisexual, in little green or brown spikes called; 

 spikelets, consisting of several scale-like bracts called glumes, either distichous as- 

 in Oraminea or imbricated all round the rhachis, with 1 sessile flower in the axil 

 of each, or the lower ones and sometimes a few at the end empty. No normal 

 perianth in the Queensland species, but replaced in some genera by 6 or ftwer, 

 rarely more, bristles or small scales. Stamens 3 or fewer or rarely 4 to 6 or 

 indefinite ; filaments free, filiform or slightly flattened ; anthers usually exserted 

 from the spikelet, attached by their base, oblong or linear, with 2 parallel cell* 

 opening longitadinally, the connective usually more or less produced beyond the 

 cells into a small point or appendage. Ovary entire, 1-celled, with 1 erect ovule ^ 

 style terminal, filiform or variously thickened at the base, more or less deeply 

 divided into 2 or 3 rarely more filiform spreading or recurved branches stigmatic 

 and papillose or rarely shortly plumose from the base, and therefore often termed 

 stigmas. Fruit a small seed-like nut, flattened when the style is 2-cleft more or 

 less distinctly 3-angled when it is 3-cleft. Seed erect, albuminous, with a smalt 

 lens-shaped globular or ovoid embryo in its base.— Herbs often resembling ia
