1. C. oblonga, Hook. f. FI. N. Z. i. 246. Very slender, 1-8 in. high. 
Leaf oblong or oblong-cordate, obtuse or acute, cordate or rounded at the

Northern Island aud northern parts of the Middle Island : frequent in shaded woods, 
Sinclair , Colenso , Travers, etc. 
2. C. rotundifolia, Hook. f. FI. N. Z. i. 246. Quite similar to C. 
ollonga , but the leaf is orbicular, and often 1-1 ^ i n - diam. 
Northern Island: east coast, Raukawa ridge, Cape Kidnapper, etc., Colenso. My C. 
macrophylla is, I think, nothing but a large state of this, which may itself prove to be a 
variety of C. oblonga.
