Description

Shrub or small tree, to 20 (rarely 35) m tall, deciduous or partly deciduous, glabrous; bark narrowly fissured with small scales, dark greyish-brown; young shoots with interpetiolar scar interrupted. Leaves with petiole 3-7 mm, 2-9 by 1-4½ cm, elliptic to oblong, apex shortly acuminate to rounded, base cuneate to subattenuate, chartaceous, not glaucous beneath. Inflorescence of 1-4-flowered cymules in lower (or sometimes also upper) axils of current shoots or, if shoot fails to develop, apparently axillary on older stems; pedicels 2-6(-8) mm. Flowers heterodistylous. Sepals 2½-5 by 1-3 mm. Petals white or pink, 6-12 by 2-5 mm; nectary scale 2-3 mm, truncate, undulate-denticulate. Stamen fascicles (5?-)7-9 mm, with stamens relatively lax, nearly always <20 per fascicle; anther gland present. Staminodial fascicles trigonous (?), linguiform, attenuate, not cucullate. Ovary 2-3 mm long; styles 1-5 mm. Capsule (6-)9-15 by 3-4(-5½) mm, c. 2½ times as long as sepals, fusiform, with columella ±2/5 as long as capsule. Seeds 5-6 per loculus, 6-6½ by 1½-2 mm, oblong to oblanceolate-oblong.

Notes

The discontinuous populations of C. maingayi tend to be morphologically distinguishable. They all differ from C. formosum, however, in the form and number of the seeds, the number of stamens per fascicle, the size of the leaves and the capsule shape.
