Leaf blades about 8-17 x 5-9.5 cm, green or slightly glaucous on the underside, clothed in straight and tortuous, erect, white or pale brown hairs. Midrib and main lateral veins depressed on the upper surface. Midrib hairy on the upper surface. Petioles flat or channelled on the upper surface. Oil dots visible with a lens.


Flowers opening very widely, the tepals remaining +/- erect at anthesis. Tepals about 1-1.9 mm long. Staminal glands absent. Staminodes absent.


Fruits ellipsoid, occasionally pyriform or globular and laterally compressed, about 33-54 x 27-41 mm. Seed about 23-31 x 15-26 mm. Cotyledons orange or apricot.


First pair of leaves elliptic to slightly obovate, about 50-90 x 19-52 mm, slightly glaucous on the underside. At the tenth leaf stage: leaves obovate, apex shortly acuminate, hairy on the upper surface along the midrib and main lateral veins, slightly glaucous on the underside; terminal bud, petioles and stem clothed in brown, tortuous hairs. Seed germination time 27 to 97 days.
