Paederia ternata Wallich in Roxburgh, Fl. Ind. 2: 520. 1824; Serissa ternata (Wallich) Kurz.
Erect shrubs 1-4 m tall, or sometimes small trees 5-6 m tall; branches angled, glabrous. Leaves in whorls of 3 or sometimes opposite; petiole 6-12 mm, glabrous; blade drying thinly leathery to papery, elliptic, oblong-lanceolate, or oblong-elliptic, 8-15 × 3-6.5 cm, both surfaces glabrous, base acute to obtuse, apex shortly acuminate; secondary veins 7-10 pairs, not joining in a submarginal vein, without domatia; stipules caducous, narrowly triangular to lanceolate, 5-12 mm, with 2-7 linear teeth or projections. Inflorescences axillary, cymose, glabrous; peduncles 1-3 per axil, 10-40 mm; bracts triangular to ovate, 1-5 mm, often aristate, usually deciduous after flowering; pedicels 2-10 mm. Flowers pedicellate. Calyx glabrous; hypanthium portion cupuliform, 2-2.5 mm, glabrous; limb 1-2 mm, shallowly and sometimes irregularly lobed; lobes triangular. Corolla tubular, puberulent to tomentulose outside; tube 3-8 mm, pilose in throat; lobes triangular usually with expanded crisped margins, 3-4 mm. Drupes ellipsoid or subglobose, 8-12 × 6-8 mm; pyrenes plano-convex, smooth abaxially. Fl. Apr, Jun, fr. Sep-Nov.
