17. C. perpusilla, Hook. f. Handb. N.Z. Fil. 143.—Often form- 
ing broad patches, more or less silky in all its parts. Rhizome 
much branched, creeping, rigid and wiry, 2-9in. long or more; 
branchlets short, erect, leafy. Leaves tufted, silky on both sur- 
faces, +-lin. long, linear-oblong or linear-obovate, deeply pinnati- 
fid; segments close-set, sometimes slightly recurved, deeply serrate 
on the upper edge or entire. Peduncles short, stout, rigid, silky, 
4+-3in. long. Heads unisexual; males }-1in. diam.; involucral 
bracts in 1 or 2 series, broadly oblong, silky, with broad purple 
scarious margins. Florets numerous, eglandular, funnel-shaped. 
Female heads larger, +4 in. diam.; involucral bracts in 3-4 series, 
larger and broader than in the males, incurved over the florets and 
often concealing them. Florets numerous; corolla ovoid, inflated 
at the base, contracted at the minutely toothed mouth. Achenes 
somewhat curved, rounded on the back or obscurely trigonous.—

Not uncommon throughout. Sea-level to 4500 ft. November-February. 
18. C. squalida, Hook. f. Handb. N.Z. Fl. 143.—Stems long, 
slender, creeping, branched, 4-12in. long or more, silky or pilose ; 
branchlets short, erect. Leaves 1-2 in. long, linear-obovate in out- 
line, petiolate, flaccid and membranous, more or less pilose with 
long soft hairs, deeply pinnatifid; segments rather lax, recurved, 
deeply incised along the upper margin or more rarely along both 
margins. Peduncles 1-3 in. long, slender, naked, silky. Heads 
unisexual; males $-4tin. diam.; involucral bracts few, in 2 series, 
broadly oblong-obovate, silky, with broad purplish scarious margins. 
Florets numerous, eglandular, funnel-shaped. Female heads larger, 
11 in. diam.; involucral bracts in 3-4 series, broad, rounded, silky, 
purplish, usually incurved over the florets and concealing them. 
Florets numerous; corolla ovoid, inflated at the base, much con- 
tracted at the mouth, minutely 4-toothed. Achene curved, rounded 
at the back, almost trigonous.— Kirk, Students’ Fl.328. Leptinella

SoutH Istanp : Not uncommon from Nelson to Foveaux Strait. Sea-level to 
4000 ft. December—February. 
Closely allied to C. perpusilla, but distinguished by the greater size, soft 
flaccid leaves with deeply incised segments, and by the larger pistillate heads, 
which have the involucral bracts so much incurved as to completely hide the 
florets. 
19. C. dioica, Hook. f. Handb. N.Z. Fl. 143.—Stems creeping, 
rather stout or slender, glabrous or slightly hairy, 3-12 in. long. 
Leaves tufted or solitary, membranous, often flaccid, petiolate,
