Description: Cumin (cuminum cyminum) is an annual plant belonging to the carrot or parsley family (Apiaceae). It usually grows between 10 to 30 cm tall with completely smooth stems that are richly branched from the ground up. The stalks are thin and rather weak, often making the stalks of larger plants grow in horizontal position on the ground.
The leaves are blue-green up to 7 cm long and the flowers are small and white or light pink in color. The flowers are hermaphrodite (contain both male stamen and female stigma) and are pollinated by insects.
The fruit (seed) is a 4-5 mm long and 2.1 mm wide, narrowly ovate schizocar (a dry fruit that, when mature, splits up into mericarps).

Cumin plants can be very variable in terms of size, number of flowers and color of the flowers and fruits.
