septate lamina of 1 to 2in. Spikelets exceedingly numerotig, brown,-about 2 

 lines long, with 8 to 5 hermaphrodite flowers, but usually oiiily the lower one 

 fertile. Glumes broad, membranous, acute, the upper ones gradually narrower 

 and more obtuse but not shorter, 2 or rarely 3 outer ones empty and sometimes almost 

 aristate, and the terminal one usually small empty or with an imperfect flower. 

 Stamens 3. Style-branches 3, short. Nut obovoid, at first triquetrous, the 

 broad obtusely conical or ovoid solid apex often as long as the nucleus or 

 endocarp. — F. v. M. Fragm. ix. 14 ; Baumea loculata, Boeckel. in LinnsBa, xxxviii.

3. C. glomeratum (clustered), E. Br. Prod. 237 ; Benth. Fl. Austr. vii. 

 404. Stems 1 to 3ft. high, terete, rather slender. Lower leaves few, erect, 

 terete, 6in. to 1ft. long or more, dilated into short sheaths, a few inner ones with 



-longer sheaths and shorter laminee. Spikelets in ovoid or nearly globular dense 

 olustiers 3 to 4 lines diameter, the lower clusters in a partial' narrow pedunculate 

 panicle, the upper ones on short and long peduncles clustered in the axils of the 

 sheathing bracts, the uppermost sessile in a more compound cluster, the whole 

 forming a narrow irregular panicle. Sheathing bracts mostly open to the'base, 

 the upper ones small and glume-like. Spikelets oblong, brown, 2 to 3 lines long. 



•Glumes membranous, broad, ciliate, acuminate, 2 or 3 outer ones empty. 

 Flowers usually 2, sometimes 3, all hermaphrodite or the upper one male and 

 usually only the lower one fertile. Stamens 8. Style-branches 3. Nut ovoid- 

 oblong, nearly as long as the glume, when unripe with 3 raised aiiglias and 



-crowned by the pubescent base of tbe style, when ripe the angles are nearly 

 obliterated and the nut is shining (red in Brown's specimens), the base of the 

 style scarcely distinct except as an^ opaque apex. — ^Kunth, Enum. ii. 304 ; Sieb.

4. C. teretifolium (leaves terete), R. Br. Prod. 287 ; Benth. Fl. Austr. vii. 

 406. Stems 1 to 3ft. high, terete or slightly compressed, striate but hot 



-angular. Leaves few, rather long, terete, acute, erect, with long' loose sheaths, 

 the inner one with a short lamina. Panicle oblong or thyrsoid, dark brown, 2 to 



•6iu. long, erect and much branched, but usually dense and nstrrow. Lowest 

 bract a loose membranous sheath with a short erect point, the others gradually 

 smaller and more glume-like. Spikelets numerous, sessile, 2 to 2^ lines long, 

 with 1 hermaphrodite flower. Glumes membranous, keeled, acutely acuminate, 

 ciliate, usually 3 empty, the outer one short, and a small glume either empty or 



-enclosing a male flower above' the flowering glume or within it. Stamens 3. 

 Nut (only seen in the Moreton Bay specimens) ovoid-globular, IJ- line long, with 

 with many much raised longitudiiiftf ridges, smooth for a very short space at the 

 base, and crowned by the scarcely distinct adnate base of the style. — Boeokel. in
