Petiole 1.5-5 cm; leaf blade ovate, 4-12 × 3-10 cm, base deeply cordate with narrow sinus, apex acuminate; basal veins 3, lateral veins to 6 pairs. Cymes umbel-like, 15-30-flowered; peduncle 0.5-1.5 cm, puberulent. Sepals oblong-lanceolate, puberulent. Corolla yellowish green; tube 6-10 × 4-6 mm, puberulent outside, pilose or glabrous with pilose throat inside; lobes oblong, 6-12 × 3-6 mm, ciliate. Corona lobes slightly fleshy, basal part ovate, apex acuminate, often notched to deeply lobed, internal appendage often longer than lobe proper. Pollinia oblong or reniform. Stigma head capitate.

The flowers are very fragrant and yield perfumed oil. They are used in cooking and medicinally to treat conjunctivitis.

Material from outside China varies greatly in corolla size and shape and, to a lesser extent, in leaf shape. It is not clear whether a species complex or a single polymorphic species, possibly including the two following species, is involved.
