Leaves elliptic to ovate-oblong, (5-)8-25 by (3-)4-14 cm, usually emarginate sometimes rounded or acute at the base, acute, sometimes acuminate at the top, tip mostly obtuse, glabrous, coriaceous, distinctly and slightly prominently reticulate beneath; Inflorescence terminal, at the end of main or side twigs, 10-25(-35) cm, branched up to the first, second or third order, whether or not peduncled, erect, with flaccid to stiff and sublignose axes; Sepals 5, triangular, l-l¼(-l½) mm, inside mostly with a longitudinal densely puberulous crest. Stamens 5; Ovary subglobose, 3-celled, 1-1½ mm, whitish papillose and/or puberulous; Capsule (sub)globose, more or less episeptally impressed, c. 2 mm; Ovules inserted on the somewhat conically elevated edges between the bases of the septs.

Notes

As appears from his drawings, C. javanica BAILL. must be referred here: bisexual flower with basal ovules; very probably they were made after a Philippine specimen. In a depauperate collection from New Guinea (NGF 2958) the panicles are axillary. In specimens from the Moluccas frequently 6-merous flowers occur among the normally 5-merous ones. In specimens from New Guinea there are usually some 4-celled ovaries and 4-celled fruits present among the predominantly 3-celled ones.
