Var, major. Stems 1^ to 2Jit. liigh. Utricles 2 lines long, prominently nerved, with a long 

 beak. 



Hab.: Brisbane Elver, F. v. Mueller. 

 The species is also in New ifealand. 



2. C. chlorantha (flowers green), II. Br. Prod. 242 ; Benth. Fl. Amtr. yii' 

 440. Stems usually under Gin. but sometimes above 1ft. Leaves much shorter. 

 Spikelets 6 to 12 sessile in a dense terminal spike of -J to lin. or rarely rather 

 longer and interrupted at the base, and then slightly compound with more 

 numerous spikelets, the spikelets all or mostly androgynous, ovoid-oblong, 2 to 3 

 lines long, usually brown. Outer bracts glume-like or rarely the lowest with a 

 subulate lamina nearly as long as the inflorescence. Glume ovate, 1 to li line 

 long, acute or mucronate, the keel usually green. Male flowers few at the top of 

 the spikelet. Utricle as long as the glume, much flattened, the edges ciliate 

 tapering into a 2-toothed beak. Style-branches 2. Nut flat. — Hook. f. Fl.

3. C. paniculata (paniculate), Linn.; Kunth, Knum. ii. 389; Benth. Fl. 

 Austr. vii. 440. Stems attaining several ft., 3-angled and often very acutely so, 

 or when old more striate with the angles less prominent. Leaves varying from 

 1 to 4 lines broad, the margins very scabrous. Spikelets "androgynous, very 

 numerous in a narrow spikelike panicle, usually 3 to 6in. long, but sometimes 

 much longer and interrupted at the base, with short erect branches or sessile 

 partial spikes, or occasionally almost reduced to that of the compound variety of 

 (J. chlorantha. Bract at the base of the panicle small and subulate or obsolete. 

 Spikelets varying from ovoid and scarcely 2 lines to lanceolate and 3 lines long, 

 usually brown. Male flowers sometimes numerous occupying at least the upper 

 half, sometimes few only. Glumes ovate, with short points. Utricle much 

 flattened, ovate, many-nerved, the margins more or less ciliate or denticulate, 

 contracted into a short 2-toothed beak. Style-branches 2. — Eeichb. Ic. Fl.

Var. subdiaphana. ' Leaves very long and glumes pale as in C. decUnatq,, ,but the utricle 

 broad and ciliate as in G. paniculata. 

 Hab.: Bockhampton, Thozet. 



4. C> declinata (curved downwards), Boott, III. Car. iv. 171, t. 580 ; Benth.- 

 Austr. vii. 441. Very closely allied to C. ■paniculata, with the same triquetrous 

 stems, scabrous foliage, inflorescence and short androgynous spikelets male at the 

 top, but the glumes are more membranous, almost white, and the utricle' 

 narrower, much less flattened, tapering into a long beak, neither ciliate nor 

 denticulate. Leaves often longer than the stem. — F. v. M. Fragm. viii. 257. 



Hab.: Brisbane Eiver, F. v. Mueller, Bailey. 



5.. C. fissilis (split), Boott, 111. Car. ii. 86, t. 2i5; Benth. Fl. Austr. vii. 441. 

 Stems 2ft. high or more. Leaves long, 3 to 4 lines broad. Brp,ets at the base 

 of the lower branches of the panicle leaflike. Panicle narrow, loose and 

 compound, 6 to Sin. long, consisting of 1 terminal and 3 or 4 distant partial 

 panicles, often 2 together from the axil of the same leafy bract, all narrow, 

 pyramidal, the rhachis ciliate on the angles. Spikelets numerous, sessile along 

 the smaller branches but not crowded, 3 to 5 lines long, androgynous, with 

 rather numerous male flowers at the top and usually B or 4 females at the base.
