Type.

Madagascar. Prov. Mahajanga: Ambongo , 16 Feb 1841, A. Pervillé 648 (lectotype, designated here: P [P00127552]!; isolectotypes: P [P00127553]!, P [P00127554]!, P [P00131420]!) .

Shrubs; western Madagascar (Mahajanga).

Notes.

The sheet chosen here as lectotype bears two labels, one on the left that lists Pervillé 648 as the collector, and one on the right in Baillon's hand that seemingly attributes the collection to Boivin, stating "ex Ambongo, cum cl. Pervillé et Bernier comm. (1846)." Baillon lists this in his protologue as a separate collection, but it looks identical to the other syntypes, so we believe it is actually part of the same collection by Pervillé.

The types lack pistillate flowers, but they are distinctive from C. brevispicatus in bearing a pair of sessile acropetiolar glands and in having relatively long petioles for the size of the leaf, and blades with a rounded-cuneate base and an acuminate apex.
