Botanical Description
Coix lacryma-jobi is a tall, stout, annual or perennial grass growing 1-2 m tall. Stems are erect, hollow, and branched. Leaves are broadly lance-shaped, 15-40 cm long and 1.5-3.5 cm wide. The plant is monoecious: male flower spikes emerge from the top of leaf sheaths, while the female florets are enclosed in hard, bead-like involucres (the pseudo-grain, Job tears). The mature involucres are hard, shiny, grey-white to blue-grey, 7-12 mm long. The actual seed (Yi Yi Ren) is white, oval, and starchy inside the hard involucre.
Moist tropical and subtropical habitats including stream banks, rice paddies, forest margins, and disturbed areas; native to Southeast Asia, widely cultivated and naturalized throughout tropical and subtropical regions.
Coix lacryma-jobi is widely cultivated throughout Asia as a food and medicinal crop and is naturalized in many regions. No conservation concerns.
