Leaf blades about 6.8-13.3 x 3-5 cm, glaucous or almost white on the underside, clothed in straight, pale brown, appressed hairs which, although not obvious, persist even on old leaves. Midrib depressed on the upper surface. Petiole flat or channelled on the upper surface. Oil dots visible with a lens.


Inflorescence paniculate, not or only slightly exceeding the leaves. Flowers unpleasantly perfumed. Lower half of the perianth tube pubescent on the inner surface. Tepals about 1.4-2.1 mm long, pubescent on the outer surface. Ovary glabrous or sparsely hairy, style glabrous or pubescent towards the base.


Fruits ellipsoid or globular, about 13-18 x 12-13 mm. Cotyledons yellow.


First pair of leaves ovate, about 45-56 x 16-31 mm, glaucous on the underside. At the tenth leaf stage: leaf blade glaucous on the underside; a few scattered pale hairs on the petiole; oil dots small, visible with a lens. Seed germination time 24 to 126 days.
