1. C. unispicea (single spike), F. v. M. Fragm. vii. 118; Benth. Fl. Amtr. 

 vii. 611. A slender grass, froin 6in. to above 1ft. high, glabrous except long 

 hairs at the orifice of the sheath, branching at the base and densely tufted. 

 Leaves short, setaceous, crowded at the base of the stem, the upper ones few and 

 capillary. Spike single, erect, unilateral, \\ to 4in. long. Outer glumes very 

 narrow, hyaline, acuminate, the lowest about 1\ line, the 2nd at least 2 lines 

 long. Flowering glume on a hairy stipes, narrow, thin, faintly 3-nerved, tapering 

 at the top, nearly as long as the outer glume, entire, with a fine awn of 2 to 3 

 lines. Terminal empty glume narrow, with a fine awn sometimes as long as, 

 sometimes much shorter than that of the flowering glume. 



Hab.: Herbert's Creek, Bowman; near Brisbane, Dr. Chat. Prentice. 



2. C. pumiliO (small), B. Br. Prod. 186 ; Benth. Fl. Austr. vii. 611. A 

 small glabrous grass, 4 to Sin. high, with the foliage of a Cynodon. Spikes 3 to 

 5, about lin. long. Spikelets narrow and crowded but all turned to one side, 

 about 2 lines long without the awn. Outer glumes very narrow, fine-pointed, 

 the longest scarcely 1 line long. Flowering glume lanceolate, scarcely ciliate, 

 deeply divided into 2 narrow lanceolate lobes produced into awns either very short 

 or nearly as long as the central one which varies from 1^ to 4 lines long. 

 Terminal empty glumes 2 or 3, lanceolate and awued. 



Hab.: Korman Greek, OulUver. 



3. C. pectinata (comb-like), Benth. Fl. Austr. vii. 612. Stems 1 to l^ft. 

 high, with the flat leaves and loose sheaths of C. barbata. Spikes 7 to 14, 2 to 

 Sin. long, the spikelets very numerous, narrow, elegantly arranged in a single 

 dense row. Outer glumes very narrow, almost subulate. Flowering glume very 

 narrow, smooth or scabrous, scarcely ciliate, with 2 narrow lobes acute or 

 produced into very short points, the intermediate almost dorsal awn very fine, 3 

 to 4 lines long. Terminal empty glume bifid, with a dorsal awn. 



Hab.: Cashmere, Armit, with purple awns and rather small awns. 



The speciee is intermediate as it were between C. pumilio and C. divaricata. — Benth. 



4. C. divaricata (spreading), R. Br. Prod. 186 ; Benth. Fl. Austr. vii. 612. 

 Star Grass. A glabrous erect tufted grass of 1 to 2ft. Leaves narrow, flat or 

 convolute, the sheaths often much flattened. Spikes 6 to 12, slender, 3 to 6in. 

 long. Spikelets very numerous, but not crowded, rarely 2 lines long without the 

 awns. Outer glumes unequal, very narrow, finely pointed. Flowering glume
