1. C. australis (southern), Hook. f. Fl. N.Z. i. 128; Benth. Fl. 

 Austr. iii. 550. Slender and diffuse, with an apparently perennial creeping 

 rhizome, more or less clothed with long soft hairs or nearly glabrous. Leaves 

 pinnate, with small pinn£B, entire or deeply 3-lobed or pinnatifid, the segments 

 mostly mucronate-aoute. Flowar-heads small, on slender peduncles. Involuora,! 

 bracts linear-oblong. Eeceptacle nearly flat. Female florets numerous, in 

 several rows, without any corollas ; disk-florets slightly dilated at the base, 

 4-toothed, fertile. Achenes of the female florets bordered by a narrow wing, 

 not cordate at the base, on pedicels nearly as long as themselves. Achenes of 

 the disk not winged, on very short pedicels. — Hook. f. Fl. Tasm. i. 191 t. 50 A ;

Hab.: Avery common weed in southern localities. 



The species is also in New Zealand and in the island of Tristan d'Acunha ; it is very near the 

 common Asiatic and African G. anthemoides, Linn., but in thai species the peduncles are usually 

 much shorter, the achenes less stlpitate, and the female florets have almost always a short 

 corolla, which I never find in C. australis even on Sieber's specimens, although described b^ De 

 Caii'doUe, who copied from Lessing. — Benth. 



2. C. alpina (alpine). Hook. f. Fl. Tasm. i. 192 t. 51 A ; Benth. Fl. Austr. 

 iii.. 550. A small but stout glabrous perennial, shortly creeping or tufted. 

 Leaves deeply pinnatifid or pinnate, with oblong-linear acute entire or 2 or 

 3-toothed segments. Flower-heads, when in fruit, fully 3 lines diameter, on 

 thick hollow peduncles, often shorter than the leaves. Involucral bracts ovate- 

 oblong. Receptacle flat or slightly convex. Female florets in several rows, 

 without any corollas. Achenes of the female florets sessile, bordered by rather 

 thick wings, those of the disk usually abortive. — Ctenosjjei-ma alpinum, Hook, f . in 

 Hook. Lond. Journ. vi. 115. 



Hab.: Logan River. 



3. C> reptans (creeping), Benth. Fl. Austr. iii. 551. A slender creeping 

 perennial, glabrous or sprinkled with a few soft hairs, especially on the peduncles. 

 Leaves pinnate, with ovate segments, toothed or pinnately divided into short 

 linear lobes. Flower-heads rarely above 2 lines diameter, on peduncles usually 

 longer than the leaves. Involucral bracts nearly orbicular. Eeceptacle conical. 

 Female florets in several rows, the corollas very short and broad, inflated, 

 contracted at the orifice, obliquely 2 or 8-toothed, the style shortly exs'erted. 

 Achenes of the female florets sessile, flattened, with thickened obtuse margins, 

 scarcely forming distinct wings, obtusely notched at the top, those of the disk 

 usually abortive. — Strongylospenna reptans, Benth. in Hueg. Enum. 60 ; DC.

Hab.: Southern localities. 



Var. major. Rather coarser, usually glabrous ; petioles and peduncles longer ; leaf-segments 

 obovate and almost succulent ; flower-heads larger. — Leptinella longipes, Hook, f . in Hook.
