Triainolepis Hook.F.

Genus

Angiosperms > Gentianales > Rubiaceae

Characteristics

Shrubs or small trees. Leaves opposite, petiolate; blades lanceolate to ovate or oblong-elliptic, often curved; stipules ovate or ovate-triangular, divided into 3–5 lobes. Flowers hermaphrodite, heterostylous, (4–)5-merous in terminal corymbs; bracts small or minute. Calyx-tube campanulate, the limb cupular, unequally 5–7-toothed. Corolla white, yellowish or tinged red, salver-shaped, tomentose to woolly outside; tube with throat and sometimes upper half inside densely barbate with white hairs; lobes lanceolate, hairy outside, glabrous inside. Stamens inserted at the top of the corolla-tube, exserted or included. Disc mostly glabrous. Ovary 4–10-locular, each locule with 2(–3) collateral erect anatropous ovules; style filiform, glabrous, exserted or included; stigma-lobes 4–10, filiform, straight or twisted, sometimes cohering. Fruits usually red, globose or depressed globose, drupaceous, containing a woody or bony 4–10-celled putamen, which is entire or slightly to deeply incised between the locules; locules 1-seeded. Seeds ellipsoid, compressed, with membranous testa and fleshy albumen.
