Flowers pedicellate, pedicels about 1-3 mm long, attached to short burrs on the twig. Calyx gland dotted, calyx tube about 0.5-1 mm long, lobes about 1 mm long. Corolla tube very short, lobes about 1.5-2.5 mm long. Anthers about 1-1.5 mm long, filaments very short. Ovary about 0.8-1.5 mm long. Stigma sessile, capitate. Ovules 3-4.

Cotyledons ovate to orbicular, about 7-9 x 6.8 mm, margins toothed with about 1-7 teeth on each side. Oil dots small, pink to red. First pair of leaves elliptic-ovate with a few teeth on both sides of the midrib. Midrib depressed on the upper surface. At the tenth leaf stage: leaf blade asymmetrical, margin toothed with about 8-10 teeth on each side mainly towards the apex. Oil dots mainly clear and orbicular. Stem and terminal bud clothed in gland-like hairs or processes. Seed germination time 97 to 146 days.
