Lenticels arranged in undulating longitudinal lines. White granular stripes generally present under the lenticels.
Twigs angular in transverse section, clothed in straight and tortuous, pale brown, appressed hairs when young, eventually becoming almost glabrous. Leaf blades about 7.5-14 x 2.9-5.7 cm, green on the underside, clothed in straight, pale brown, appressed hairs when very young but soon becoming almost completely glabrous. Midrib flush with the upper surface. Petioles flat on the upper surface. Leaves tend to be alternate and not spirally arranged on the twigs which are often zig-zagged at the leaf bearing stage. Lateral veins curving and often forming loops well inside the blade margin. Oil dots visible with a lens.
Inflorescence paniculate, not exceeding the leaves. Flowers faintly but pleasantly perfumed. Lower half of the perianth tube usually pubescent (rarely glabrous) on the inner surface. Perianth tube short, not enclosing the ovary. Tepals about 1.5-2 mm long, pubescent on the outer surface. Ovary and style glabrous.
First pair of leaves ovate to lanceolate, about 70-110 x 28-40 mm, green on the underside. Apex of the leaf drawn out to a long point. At the tenth leaf stage: leaf blade very long, apex acuminate; oil dots small, numerous, visible only with a lens. Seedling glabrous except for a few hairs on the growing tips.
