Fruit

Individual fruiting carpels about 5 mm long. Seeds about 2 mm diam. Testa +/- smooth or minutely rugose.

Seedlings

Cotyledons about 7-12 mm long, margins +/- smooth to slightly crenate. First pair of leaves with crenate margins at least in the upper half. At the tenth leaf stage: leaf blade narrowly elliptic, apex acute or bluntly acuminate, base attenuate; midrib green, raised on the upper surface; lateral veins forming definite loops inside the blade margin; oil dots numerous, visible to the naked eye and readily visible with a lens; crushed leaves emit a strong odour. Seed germination time 24 to 44 days.
