Stamens fused into fascicles opposite the petals, stamens 3-4(-6) per fascicle, fascicles shorter than the petals. Ovary apex pubescent. Style about 1.5 mm long.
Cotyledons wider than long, bilobed, about 2-3 x 4-6 mm, apex broadly emarginate, base cordate or truncate. Oil dots very small, visible only with a lens.
