6. C. volenmunn ieee: Veg. N.Z. (1921) Stk “SPamslong, rather 
stout, creeping and rooting, branched, sparingly villous towards the 
tips; branches ascending. Leaves 2-5 in. long; peticle #-2 in., sheathing 
at the base; blade 1-3 in., linear-obovate, membranous, glabrate or slightly 
silky, gland-dotted, deeply pinnatifid ; segments oblong, closely toothed or 
lobed, teeth acute. Peduncles 1-3 in. long, usually shorter than the leaves, 
pubescent. Heads din. diam.; involucral bracts in about 3 series, oblong- 
cvate, obtuse or subacute, membranous. Female florets in many rows, 
usually mere numerous than the disc-florets; corolla short, ovoid, not 
glandular. Disc-florets larger ; corolla tubular, 4-toothed ; style undivided. 
Achenes of the female florets clavate, tetragonous.—C. Mueilert 7. Kork

This was apparently referred to C. lanata by Sir J. D. Hookcr (Handbook, p. 733), 
but it differs from that plant in being much less woolly, in the larger leaves with broader 
toothed segments, longer peduncles, and glandless florets. As Mueller’s name of 
potentillina is certainly the oldest and consequently entitled to priority I am following 
Cockayne in using it here. 
7. ©. Traillii 7. Airk Students’ Fl. (1899) 324.—Stems slender, creeping 
and rooting, 3-12 in. long, silky towards the tips. Leaves 1-3 in.; petiole 
slender, sheathing at the base ; blade linear-obovate, membranous, glabrate 
or with scattered lax hairs on both surfaces, deeply pinnatifid; segments 
close-set, broadly oblong, toothed on the upper margin and round the apex, 
teeth apiculate or hair-tipped. Peduncles axillary, pubescent, usually 
shorter than the leaves. Heads 4 in. diam., involucral bracts in 2-3 series, 
orbicular-ovate, membranous, with scarious purplish margins. Female 
florets few, in | series, shortly stipitate ; corolla ovoid, compressed. Dise- 
florets very numerous, funnel-shaped, 4-lobed; style undivided, with a 
discoid stigma. Achenes of the female florets broadly ovoid or almost 
orbicular, turgid, 3-winged.—Cheesem. Man. N.Z. Fl. (1906) 354.

Very closely allied to C. potentillina, of which it may be a variety. The habit is the 
same, and the Jeaves can only be distinguished by the smaller size and apiculate 
segments. But the heads are markedly different in the few female florets, which are 
in one row only, and have much broader achenes. 
8. C. Maniototo Petrie in Trans. N.Z. Inst. xiv (1882) 362.—Small, 
densely matted, forming broad greyish patches; everywhere covered with 
long silky hairs. Stems $-3 in. long, creeping and rooting; branches very 
short, leafy. Leaves numerous, silky on both surfaces, dilated and sheath- 
ing at the base, 4-41n. long, linear-oblong, deeply pinnatifid; segments 
narrow-linear, acute. Heads terminating the branches, almost sessile, 
minute, ;4-$in. diam.; involucral bracts in 2 series, broadly oblong or 
obovate, obtuse, silky on the outside, membranous. Female florets in 1 
or 2 series ; corolla narrow-tubular, almost filiform, with a 2-lipped mouth ; 
style exserted, 2-fid. Disc-florets much larger; corolla funnel-shaped with 
a long tube, 4-5-toothed; anthers and style exserted. Achenes of the 
female florets oblong. smooth and turgid, hardly winged; those of the 
disc-flerets minute, abortive.—T. Kirk Students’ Fl. (1899) 323; Cheesem.
