Male flowers terminal on the short lateral branchlets, in fascicles of three or sometimes more; each fascicle enclosed at its base by a cupular involucel, apparently formed of metamorphosed stipules; calyx short-cupular, with four or fewer short blunt lobes; corolla bell-shaped, fourpartite almost to base; stamens exserted; the fascicles of male are often on twigs destitute of leaves.

Female flowers terminal on the short lateral branches, usually solitary, but sometimes two or three together, with a four-lobed tubular more or less ciliated involucel enclosing the calyx; calyx tubular, indistinctly four-lobed at the ciliated margin; corolla four-partite to base; the lobes narrow, oblong; styles papillose, twice as long as the corolla lobes; drape not seen.

Habitat: Dunedin, Water of Leith, Vauxhall, Saddle Hill, where it was first gathered by Mr. A. C. Purdie.

The species belongs to the group with fascicled female flowers, and is very distinct and well marked in its characters. It appears to be closely allied to another undescribed species growing near Dunedin, and forming a link between it and C. rotundifolia.
