The species appears to be related to C. parviceps.
Tree, hemi-epiphytic or terrestrial, often (?)
deciduous, up to 20 m tall. Leafy twigs 3-6 mm
thick, glabrous or puberulous on the scars of the
stipules. Lamina chartaceous, ovate to elliptic or
to obtuse, occasionally obovate, 4-16 x 1-7 cm,
apex acute to acuminate to obtuse, base obtuse
sometimes subacute or subcordate, margin en-
tire; both surfaces glabrous; lateral veins 4-6 pairs,
curved, basal pair unbranched reaching the mar-
gin below, at, or slightly above the middle of the
lamina; intercostal venation plane; petiole 1-5
cm long, glabrous; stipules 1-3 cm long, glabrous
or sparsely to densely appressed-puberulous.
Staminate inflorescences branched; heads 2-6,
globose, ca. 5-8 mm diam.; common peduncle
2-4 cm long, glabrous; perianth ca. 1 mm high,
glabrous or sparsely minutely puberulous; sta-
