Cumin is the dried seed of the herb Cuminum cyminum, a member of the parsley family. The cumin plant grows to 30–50 cm (12–20 in) tall and is harvested by hand. It is an annualherbaceous plant, with a slender, glabrous, branched stem that is 20–30 cm (8–12 in) tall and has a diameter of 3–5 cm (11⁄4–2 in). Each branch has two to three sub-branches. All the branches attain the same height, so the plant has a uniform canopy. The stem is colored grey or dark green. The leaves are 5–10 cm (2–4 in) long, pinnate or bipinnate, with thread-like leaflets. The flowers are small, white or pink, and borne in umbels. Each umbel has five to seven umbellets. The fruit is a lateral fusiform or ovoidachene 4–5 mm (1⁄6–1⁄5 in) long, containing two mericarps with a single seed. Cumin seeds have eight ridges with oil canals. They resemble caraway seeds, being oblong in shape, longitudinally ridged, and yellow-brown in color, like other members of the family Apiaceae (Umbelliferae) such as caraway, parsley, and dill.
