Laterally elongated speckles usually visible in the outer blaze.


Twigs fluted, clothed in straight, white or pale brown, appressed hairs when young but soon becoming almost glabrous. Leaf blades about 6.5-15.5 x 3-7.5 cm, slightly glaucous on the underside, clothed in short, straight, white or pale brown, appressed hairs which, although difficult to see, persist even on mature leaves. Domatia (tufts of hair) normally present in the axils of the basal pair of primary veins. Midrib depressed on the upper surface. Petioles flat or channelled on the upper surface. Oil dots visible with a lens. Basal pair of lateral veins extend from almost the base of the leaf blade to at least halfway to the apex.


Inflorescence paniculate, exceeding the leaves. Flowers unpleasantly perfumed. Lower half of the perianth tube glabrous or pubescent on the inner surface. Tepals about 1.6-2.4 mm long, pubescent on the outer surface. Ovary and style glabrous.


Fruits globular or depressed globular, about 13-20 x 14-22 mm. Cotyledons white or cream.


First pair of leaves ovate, about 45-80 x 25-45, glaucous on the underside. At the tenth leaf stage: leaf blade glaucous on the underside; domatia (small tufts of hair) sometimes present; oil dots small, numerous, visible only with a lens. Petiole hairy. Seed germination time 36 to 96 days.
