margins. Receptacle conical. Female florets in 2—3 series ; corolla filiform^ 



scarcely expanded at the 2-lipped mouth; achenes oblong, with a narrow border, 



slightly turgid. Hermaphrodite florets longer, narrow, trumpet-shaped, 4-lobed.

 Jan., Feb. 



Petrie describes the female florets as 1-seriate, but in my specimens they are invariably 

 2-3-seriate. 



7. C. Muelleri, T. Kirk. Habit of C. Traillii, but stems and leaves 

 more robust. Leaves shorter, gland-dotted, glabrate ; petiole stout ; segments 

 subovate, crenate-toothed or lobed, never apiculate. Scapes axillary, downy or 

 pubescent. Heads hemispherical ; involucral bracts about 30, in 3 series, the 

 outer short, ovate, acute ; the inner oblong-ovate or cuneate-ovate, membranous, 

 glabrate or glabrous. Receptacle convex. Female florets in about 3 rows, 

 eglandular ; corolla shortly ovate, one-third to one-half the length of the achene ; 

 style-arms very short ; achenes oblong, clavate, narrowly winged. Herma- 

 phrodite florets less numerous ; corolla slightly tetragonous, 4-lobed ; stigma 

 undivided. — Leptinella potentillina, F. Muell., Veg. Chath. Isds. 28, t. 6. 



CHATHAM Islands, H. Travers I Cox ! 



This bears a close resemblance to C. Traillii, but the leaves are larger and more fleshy, the 

 involucral bracts narrower, while the female florets are very numerous, usually exceeding the male, 

 and the achenes are much narrower. C. lanata, to which Sir Joseph Hooker seems inclined to refer 

 it (Handbook 733), differs in the robust woolly branches, very short stout terminal peduncle and 

 glandular florets, with the corolla of the female equalling the achene. 



8. C. Traillii, n. s. Stems slender, creeping, 3in.— 12in. long. Leaves 

 tufted, membranous, liuear-obovate, with a few scattered hairs on one or both 

 surfaces, deeply pinnatifid ; segments in 7—9 pairs, acutely toothed or apiculate, 

 especially above ; terminal lobes very large and broad ; petiole slender, winged 

 at the base. Peduncles axillary, equalling the leaves or shorter, pubescent or 

 hairy. Heads hemispherical, ^in. in diameter ; involucral bracts few, in 2—3 

 rows, orbicular or orbicular -ovate, with erose scarious margins. Receptacle 

 flat or slightly convex. Female florets few, sparingly glandular, shortly 

 stipitate ; corolla ovate, compressed ; achene broadly ovate or suborbicular, 

 scarcely twice as long as the corolla and much broader, obviously 3-winged, 

 sligbtly turgid and convex at the back. Disk-florets very numerous, funnel- 

 shaped, 4-lobed; stigma discoid. 



STEWART Island : often on blown sand, T. K. Dec. to Feb. 



This species is closely related to C. lanata and C. Muelleri, from both of which it is dis- 

 tinguished by the more slender habit, acutely toothed leaves, and the short broad achenes, which 

 are very few in number and invariably confined to the outside row. 



9. C. minor, Hook. /., Handbk. 142. Stems very slender, creeping, 

 glabrate or pubescent, lin.-12in. long. Leaves radical, or alternate on slender 

 creeping runners, linear-oblong or obovate in outline, Jin.-2in. long, pinnatifid 

 nearly to the base; the lower segments rather di-stant, and deeply lobed or 

 toothed on the upper margins ; the upper segments close-set and recurved.
