Clematis. | RANUNCULACES. 3 
A variable plant, but easily recognised by its great size and large showy 
white flowers. The leaves are usually entire, but are occasionally lobulate, 
especially in young plants. Mr. Kirk’s variety linearis, which has narrow- 
linear leaves, 4-6in. long by barely din. broad, appears to me to be only a 
transient juvenile form. 
2.C. hexasepala, D.C. Syst. i. 146.—Much smaller and more 
slender than U. indivisa. Leaves 3-foliolate, pale-green, coriaceous, 
glabrous; leaflets 1-3in. long, stalked, narrow ovate-oblong or 
ovate-cordate, acute or acuminate, usually irregularly toothed or 
lobed, rarely entire. Flowers numerous, 1l-l4in. diam., white. 
Sepals 6-8, linear-oblong, obtuse, downy. Anthers long, linear, 
obtuse. Achenes numerous, narrow-ovoid, pilose.—dA. Cunn.

Nort Isuanp: From the Kaipara Harbour to Cook Strait; not uncommon, 
especially in the Upper Waikato and Taupo districts. SourH Istanp: Queen 
Charlotte Sound, Forster; near Moutere (Nelson), 7’. #7. C. Recorded from 
Canterbury (Armstrong), Otago (Lindsay), and the Bluff Hill (Kirk). Prki- 
arero. September—November. 
Hasily separated from C. indivisa by the smaller size, narrower pale- 
green leaves, which are almost always toothed, and by the smaller flowers. 
3. C. australis, 7. Kirk, Students’ Fl. 3.—Stems and branches 
slender, much branched, glabrous or pubescent at the tips. Leaves 
3-foliolate, glabrous, somewhat coriaceous (especially in the small- 
leaved forms) ; leaflets very variable in size, 4-lin. long, pinnate 
or pinnately lobed, segments or lobes usually again toothed or lobed. 
Flowers white, 4-lin. diam., in few-flowered panicles or solitary 
on long slender peduncles clustered in the axils of the leaves. 
Sepals 5-8, downy. Achenes narrowed into the style, usually 
pilose, sometimes glabrous when fully mature. 
SoutH Isnanp: Hilly and mountain districts in Nelson and Canterbury, 
not uncommon. 500-3500 ft. November—January. 
A puzzling plant, large states of which can only be separated from 
C. hexasepala by the pinnately divided leaflets, while smaller forms come 
very nearly to C. Colenso1 var. rutaefolia, from which, however, it can usually 
be distinguished by the larger white flowers and more pointed sepals. 
4. ©. Colensoi, Hook. f. Handb. N.Z. Fl. 2.—Stems and 
branches slender, glabrous or silky at the tips. Leaves 3-folio- 
late, membranous or slightly coriaceous; leaflets stalked, 4-14 in. 
long, crenate, unequally toothed or 3-lobed, or again ternately or 
pinnately divided. Flowers greenish-yellow, 4-1 in. diam., in few- 
or many-flowered panicles, or more usually solitary on slender 
peduncles fascicled in the axils of the leaves. Sepals 5-8, oblong, 
silky. Anthers linear. Achenes silky or sometimes nearly glabrous 
when mature.—Kirk, Students’ Fl. 8. C. hexasepala, Hook. f. 
Fl. Nov. Zel. i. 7 (not of D.C.).
