1. C. dentex (leaves toothed), li. Br. inBot. Reg. under n. 504 ; Benth. Fl. 

 Aiistr. iii. 501. A perennial, with nearly simple or branched erect or decumbent 

 stems, attaining sometimes 2 or 3ft., scabrous-pubescent or hispid. Leaves 

 linear, lanceolate or oblong, usually acute,, acutely and remotely toothed or 

 pinnatifid, mostly 1 to 2in. long, often dilated into stem-clasping auricles. 

 Flower-heads pedunculate. Involucre hemispherical, scabrous-pubescent ; bracts 

 not numerous, ovate, 8 or 5-nerved, almost membranous, the narrow inner ones 

 very few or none. Achenes of the ray flat, obovate, scabrous or almost muricate. 

 Pappus of 2 or 3 broad truncate scales, almost united into a fringed cup, and 1 or 

 more frequently 2 rigid bristles or awns, barbed at the end only.— DO, Prod, 

 v. 302. 



Hab.: Burdekin River, F. v. Mueller; Brisbane River, Moreton Bay, Leichhardt, W. Hill. 

 Abundant on hillsides. 



2. Ci cuneifolia (leaves wedge-shaped), i?. Br. in Bot. lieij. t. 504 ; Benth. 

 Fl. Austr. iii. 501. An erect or spreading branching perennial, rarely attaining 

 1ft., more or less hoary, scabrous- pubescent or hirsute. Leaves oblong, cuneate 

 or spathulate, sometimes almost orbicular, coarsely toothed, narrowed into a 

 short or long petiole dilated into stem-clasping auricles. Flower-heads hemi- 

 spherical, becoming globular when in fruit, on terminal peduncles. Involucral 

 bracts oval, oblong or lanceolate, about 2 lines long. Ray-florets long and 

 narrow. Achenes flat, short, obovate. Pappus of 8 rigid barbed bristles or awns, 

 and 2 broad membranous truncate scales, quite distinct, and sometimes a third 

 smaller one. Disk-achenes abortive. Fruiting-heads forming a globular burr of 

 3 or 4 lines diameter. — DC. Prod. v. 302 ; C. dilitata, A. Cunn.; DC. I.e. 



Hab.; Suttor River, Thozet ; Burdekin Eiver. Common on inland downs.

 400, PL Vict. t. 36 ; Benth. Fl. Austr. iii. 502. Apparently perennial, with 

 ascending stems of about 1ft., slightly scabrous-pubescent. Lower leaves linear- 

 cuneate or oblong, coarsely toothed, 1 to 2in. long, narrowed into a long petiole ; 

 upper ones smaller, sessile, linear or lanceolate, entire. Involucral bracts ovate. 

 Eay-florets numerous, narrow. Achenes flat, obovate, crowned by 2 rigid 

 divaricate scales, broad and concave, almost boat-shaped at the base, tapering 

 into short rigid barbed awns, the summit of the achene convex within the scales.

Hab.: Inland localities. 



Var. pumila. Under 6in. high and flowering the first year, so as to appear annual, pubescent 

 or hirsute. Flower-heads small. Scales of the pappus not so broad at the base, and tapering 

 into longer, more densely barbed awns. — Near Cooper's Creek.
