Woody climbers or suberect shrubs, evergreen. Branchlets glabrous. Petiole to 1.2 cm; leaf blade elliptic-oblong to lanceolate, 5-22 × 1.5-8 cm, papery to leathery, both surfaces glabrous, lateral veins 6-12 pairs, obvious, straight or sometimes curved, base cuneate or cordate, apex acute or acuminate. Cymes 10-30-flowered, solitary, axillary or arranged in axillary panicles 1.5-7 cm, glabrous. Pedicel to 1.3 cm; bracteoles ovate to oblong-ovate, to 1.2 mm, often near calyx, glabrous, ciliolate or not. Sepals 5, broadly ovate to ovate, 0.75-1.25(-2) × 0.7-1(-1.5) mm, glabrous, ciliolate or not, apex acute to obtuse. Petals 5, green to white, oblong-ovate to oblong, 3.5-5.5 × 1.5-2 mm, veins to 6, but often obscured by many "granules" forming dotted lines, apex acute or narrowly obtuse. Stamens 1.5-2.5 mm; filaments flattened, 1.2-2 mm, 0.3-0.5 mm wide; anthers inflexed, globose or ellipsoid, ca. 0.3 mm. Disk crown-shaped; lobes short, but often with distinctly disciform apices. Ovary broadly transversely ellipsoid, 0.6-0.75 × 0.7-1 mm, glabrous. Schizocarp probably blue when fresh, distinctly obovoid to oblong-obovoid or pyriform, somewhat compressed, 1.2-1.5 cm × 7-10 mm, with or without persistent petals and stamens at base, reticulate pattern faint or absent.
