17i2 CLII. CYPERAOE^. [Cyperus. 



bracts few, of which 1 or 2 longer than the inflorescence. Spikelets linear or 

 linear-lanceolate, very flat, elegantly pinnate, of a pale brown, ^ to nearly lin. 

 long, above 1 line broad, 20 to 40-flowered, the rhachis slender, not winged. 

 Glumes loosely but regularly distichous, narrow, obtuse, but the pale-coloured or 

 almost hyaline keel produced into a fine straight or recurved point, the sides very 

 prominently 2 or 8-nerved, the lower glumes very deciduous, giving the older 

 spikelets a pedicellate appearance, the 2 small ovate empty glumes remaining 

 persistent at the base of the rhachis. Stamens 3. Style 3-cIeft. Nut linear- 

 oblong, more than half the length of the glume.

82. C. fulvus (tawny), R. Br. Prod. 213 ; Benlh. Fl. Austr. vii. 274. Stems 

 from under 1ft. to above 2ft. high, obtusely 3-angled. Leaves narrow, sometimes 

 as long as the stem. Spikelets 6 to 12 together in dense heads or clusters in a 

 simple or compound umbel of 5 to 10 rays, the longest rarely 2in. long. 

 Involucral bracts 2 usually longer than the inflorescence and sometimes very long, 

 with 1 or 2 short ones. Spikelets very spreading, linear-lanceolate, rather acute, 

 flat but rather thick, of a golden brown or pale-coloured, 2 to 3 or rarely 4 lines 

 long, about 1 line broad, 8 to 12-flowered, the rhachis not winged. Glumes 

 loosely imbricate or at length rather spreading, narrow, obtuse, or almost acute, 

 with 2 or 8 prominent nerves on each side of the keel. Style 3-cleft. Nut 

 oblong, 3-angled, more than half the length of the glume. — F. v. M. Fragm. viii.

33. C. carinatus (keeled), /.'. Br. Prod. 216; BentJi. Fl. Austr. vii. 274. 

 Stems 6in. to IHt. high, obtusely triquetrous. Leaves maeh shorter, crowded in 

 the tufts, rather broad, tapering to a fine point. Spikelets in dense clusters or 

 heads in an umbel of few rays, the longest 1 to 2in. long. Involucral bracts 3 or 

 4, of which 1 or 2 longer than the inflorescence and 1 often very long. Spikelets 

 spreading, linear or linear-lanceolate, flat but rather thick, with a loose pinnate 

 aspect, 4 to 6 lines long or when old rather longer, nearly 2 lines broad, 10 to 

 ;80-flowered, the rhachis not winged or scarcely perceptibly bordered. Glumes 

 not closely imbricated, short and rather broad, spreading, obtuse, the keel 

 prominent and often produced into a short straight or recurved point, the sides 8 

 or 4-nerved. Stamens 3. Style 3-cleft. Nut obovate-oblong, 8-angled, more 

 than half the length of the glume.

The species is very near C. /«ta(s, but the glumes are much shorter and broader as well as 

 looser in the spikelets, giving the inflorescence a very different aspect approaching that of C. 

 alternifiorus. — Benth. 



84. C. alternifiorus (alternate flowers), E. Br. Prod. 216; Benth. FL Austr. 

 vii. 275. Stems rather stout, acutely 3-angled, 2 to 3ft. high. Leaves often 

 longer than the stem, 2 to 4 lines broad at the base, with very scabrous edges. 

 Spikelets densely clustered as in the preceding species, but the common rhachis 

 often slightly elongated, the clusters becoming short dense spikes, in a compound 

 umbel of 6 to 10 rays, the longest 3 to 4in. long, or all short and dense. 

 Involucra,l bracts 1 or 2 very long, sometimes near 2ft. and very scabrous like the 

 leaves, with 1 or 2 short ones. Spikelets spreading, of a rich or a pale b;rown, 

 linear, flat, 4 to 10 lines long, nearly 1^ line broaa, 10 to 30-flowered, the 

 rhachis not winged. Glumes narrow, spreading and very loosely imbricate, 

 rather acute, the keel prominent, with 3 or 4 nerves on each side. Stamens 2 or
