rather more, and about 1 line broad when fully out, with 10 to 16 or rarely more 

 flowers, the rhaehis bordered by scarious wings often partially deciduous. Glumes 

 loosely imbricate but scarcely spreading, obtuse or almost acute, keeled, with 3 or 

 4 nerves on each side. Stamens 3. Style 3-cleft. Nut broadly oblong, 

 triquetrous, not quite half the length of the glume.— F. v. M. Fragm. viii. 269 ; 

 C. carinatus, Nees in PI. Preiss. ii. 72, not of E. Br. 



Hab.: Queensland, F. v. M. 



The species is chiefly South African. 



45. C. subulatus (awl-shaped), E. Br. Prod. 217 ; Betith. Fl. Aiistr. vii. 281. 

 Stems from a creeping rhizome rather slender, under 1ft. high in the specimens 

 seen. Leaves very narrow, often as long as the stem. Spikelets in dense 

 clusters or short spikes in an umbel of few rays. Involucral bracts very narrow, 

 almost filiform, 1 or 2 of them longer than the inflorescence. Spikelets brown, 

 linear, acute, not very flat, 6 to 8 lines long and scarcely 1 line broad, 

 12 to 20-flowered, the rhaehis bordered by hyaline wings. Glume rather 

 narrow, erect but not very closely imbricate, acute or scarcely obtuse, the keel 

 green, 8-nerved, or sometimes 5-nerved, the sides brown and nerveless. Style 

 3-cleft. Nut rather broad, triquetrous, more than half the length of the glume.

46. C- sporobolus (Sporobolus-like), 2?. Br Prod. 215 Bmth. Fl. Atistr. vii. 

 281. Stems usually rigid but not very stout, obtusely triquetrous, from under 

 1 to lift. high. Leaves much shorter. Spikelets in little globular heads or 

 clusters in a compound umbel of 5 to 10 very unequal rays, the longer ones 1 to 

 Sin. long, the clusters or heads at first 2 to 3 lines diameter but expanding to 4 

 or 5 lines. Involucral bracts few, of which 2 ov 3 much longer than the 

 inflorescence and sometimes very long. Spikelets spreading, flat, rarely above 2 

 lines long, with 5 to 8 flowers, the rhaehis very short, but more or less distinctly 

 bordered by hyaline wings. Glumes rather narrow, spreading, strongly several- 

 nerved, the keel sometimes produced into a minute point. Style 3-cleft. Nut 

 oblong, triquetrous, more than half as long as the glume. 



Hab.: Island of the Gulf of Carpentaria, R. Brown ; Sweers Island, Memie, with rather large 

 spikelets and very spreading glumes. 



0. se.vflorus and C. microceplialus, K. Br. I.e. both from the same localities in the Gulf of 

 Carpentaria, appear to me to be slight varieties of C. spornboliis, with smaller heads of spikelets 

 and fewer flowers in each spikelet. — lienth. 



'47. C. angustatus (narrow), B. Br. Prod. 214; Benth. Fl. Amtr. vii. 282. 

 Stems rather slender, obtusely triquetrous, 1 to 3ft. high. Leaves narrow, 

 mostly shorter than the stem. Spikelets 4 to 10 together in close 

 clusters in a compound spreading umbel of 6 to 12 or even more slender 

 rays, the longest often 3 or 4in. long. Involucral bracts narrow, 1 or 2 longer 

 than the inflorescence and sometimes very long. Spikelets very spreading, 

 linear, scarcely flattened, rather acute, brown or pale coloured, 4 to 8 lines long 

 when fully out and scarcely above J line broad, with 10 to 20 flowers, the rhaehis 

 bordered by narrow hyaline wings. Glumes appressed or rarely slightly 

 spreadmg, rather narrow, the keel produced into a small point, the sides striate 

 with 2 or 3 prominent nerves. Style 3-cleft. Nut narrow-oblong, sometimes 

 shghtly clavate, triquetrous, nearly as long as the glume.— Boeckel. in Linnfea, 

 xxxviii. 366.

48. C. Novse-Hollandise (New Holland), Bm^kel. hi Linn/ra, xxwi. 344 ; 

 Benth. Fl. Austr. vii. 282. Ehizome thick aud hard. Stems stout, acutely 

 8-angled in the upper part, 3 to 4ft. high. Leaves often longer than the stem, 

 the sheath long, the lamina keeled below flat upwards and 2 to S lines broad.
