Inflorescence shorter than the leaves, each umbel with about 11-13 flowers. Peduncles about 20-30 mm long. Pedicels about 7-10 mm long. Tepals about 15-22 mm long, puberulent on the outer surface, mainly glabrous on the inner surface, villous near the base. Stamens sessile, anthers about 2.5-3 mm long.

Embryo about 10-15 x 25-30 mm. Seeds separated from one another in the follicle by pale brown layers of seed-like placental material.


Cotyledons sessile, shaped like a fan, about 20-23 x 30-35 mm, apex rounded, base sagittate. First pair of leaves narrowly elliptic. At the tenth leaf stage: leaf blade narrowly elliptic, apex acute, base attenuate, midrib raised on the upper surface of the leaf blade. Seed germination time 22 days.
