Leaf blades about 8.5-16 x 3-6.5 cm, green on the underside, clothed in straight, white or pale brown, appressed hairs when young but soon becoming glabrous. Midrib raised (usually in a depression) on the upper surface. Petioles flat or shallowly channelled on the upper surface. Oil dots visible with a lens.


Inflorescence paniculate, not exceeding the leaves. Flowers faintly perfumed or sweetly scented. Perianth tube pubescent on the inner surface only near the apex. Tepals about 1.6-1.8 mm long, pubescent on the outer surface. Ovary and style glabrous.
