Flowers

Individual flowers pedicellate. Operculum conical or broadly conical, about 5-7 mm diam., equal to or shorter than the calyx tube (hypanthium). Peduncles +/- square in transverse section. Outer and inner operculum shed together as one unit.

Fruit

Fruits urceolate, hard and woody, about 15-17 x 11-13 mm. Valves 3-4, deeply included. Seeds with a wing at one end.

Seedlings

Cotyledons much wider than long. Oil dots difficult to see with a lens, almost confined to the margins. At the tenth leaf stage: leaf blade ovate, apex apiculate, base obtuse with a few bristle-like hairs on the upper surface along the midrib; oil dots sparse and difficult to see with a lens; midrib on the underside of the leaf blade, petiole and stem clothed in bristle-like reddish brown hairs. Lignotuber present. Seed germination time 6 to 14 days.
