leaflets toothed or lobed, but all run into varieties in which the leaves are biternate 
or decompound, the ultimate segments being much reduced in size. These forms are 
most difficult of discrimination, “especially when in a flowerless condition, and some 
of them are probably not permanent states.

1. ©. indivisa Willd. Sp. Plant. 11 (1799) 1291.—A large woody climber, 
often covering bushes or small trees. Stems stout, frequently as thick 
as a man’s arm. Leaves of adult plants 3-foliolate, coriaceous, glabrous ; 
leaflets 1-4in. long, all stalked, ovate-oblong or ovate-cordate, rarely 
narrower and linear-oblong, lobed or more commonly entire. Leaves of 
seedling plants narrow-linear, 3-4in. long, 4-4in. broad. These are 
followed by trifoliolate leaves with linear leaflets, which in their turn are 
succeeded by others in which the leaflets are broader, and much cut and 
lobed, the leaves occasionally being twice ternate. Flowers in axillary 
panicles, most abundantly produced, large, white, 2-4 in. diam., the males 
much the largest. Sepals 6-8, oblong. Anthers oblong, obtuse. Achenes 
numerous, downy, with a plumose tail often more than 2 in. long.—A. Rich.

I have elsewhere proved (Trans. N.Z. Inst. xlvi (1914) 1) that Kirk’s two varieties 
lobulata and linearis represent the foliage of young plants. 
2. C. hexasepala DC. Syst. i (1818) 146—Much smaller and more 
slender than C. indivisa. Leaves 3-foliolate, pale-green, coriaceous, glabrous ; 
leaflets 1-3 in. long, stalked, narrow ovate-oblong or ovate-cordate, acute 
or acuminate, usually irregularly toothed or lobed, rarely entire. Flowers 
numerous, 1-13 in. diam., white. Sepals 6-8, linear- oblong, obtuse, downy. 
Anthers long, linear, obtuse. Achenes numerous, narrow-ovoid, pilose.—
