Oil dots red, the larger ones visible to the naked eye, the smaller ones visible with a lens. Lateral veins difficult to see, 14-19 on each side of the midrib, forming loops inside the blade margin. Terminal buds clothed in reddish brown hairs.


Inflorescences produced in the axils of the leaves. Flowers shortly stalked, attached to a short spur or burr. Calyx and corolla marked with orange-yellow or orange-brown oil glands. Corolla lobes about 1.5-3 mm long. Anthers sessile. Ovary orange with about 2-3 ovules embedded in a glandular placenta attached to the base of the ovary. Stigma sessile, capitate.

Cotyledons about 2-4 x 1-3 mm, margins with a few teeth. First pair of leaves obovate, margins coarsely toothed with 2-3 teeth on each side. At the tenth leaf stage: leaf blade margin coarsely toothed with about 8-11 teeth on each side. Midrib raised on the upper surface of the leaf blade. Oil dots orange-red, orbicular, visible with a lens. Stem and terminal bud clothed in reddish gland-like hairs or processes. Seed germination time 136 to 208 days.
