Blaze layering quite distinct.


Leaf blades about 10-14 x 3.5-5 cm. Lateral veins form loops well inside the blade margin. Young shoots and twigs clothed in short brown hairs. Crushed leaves may emit an odour like that of sarsaparilla.


Inflorescence about 6 cm long, not exceeding the leaves. Male flowers: Flowers with pedicels about 5-9 mm long, tepals about 1-1.5 mm long. Stamens about 50-55, staminal filaments about 2 mm long, inserted among the disk glands and long hairs. Disk glands about 0.7 mm long. Female flowers: Flowers with pedicels up to 9-14 mm long, tepals about 3-4 mm long, disk glands up to 2 mm long. Ovary about 3 x 2 mm, pubescent, ovules 2 per locule. Styles about 3-4 mm long.


Fruits globular, about 20 mm diam., disintegrating at maturity. Seeds about 12 x 5.5-6 mm. Embryo about 10 mm long, cotyledons green, flat, much wider than the radicle.


Cotyledons elliptic to elliptic-obovate, about 20-25 x 14 mm. At the tenth leaf stage: leaves ovate or elongate-ovate, apex acuminate, base cuneate, a few hairs present on the upper surface at least along the midrib; petioles, stem and terminal bud clothed in pale brown hairs. Seed germination time 14 to 15 days.
