Botanically, Job's tears is described as an annual, erect grass, 1- 2 m tall, with maize-like brace roots that grow from the lower nodes. The grass is monoecious, having separate male and female flowers on different parts of the plant. The female flowers produce yellow, purple or brown seeds, often tearshaped (hence the name). Soft-shelled varieties are eaten (Coix lacryma-jobi var. ma-yuen) and hard-shelled varieties (Coix lacryma-jobi var. stenocarpa and var. monilifer) are often used as ornamental beads.

수확 및 종자 생산
The stalk begins to dry when most of the seeds are mature. After threshing and husking the grain (either manually or with the same tools used for rice), it is dried for storage. Under humid conditions, the grain does not store well, although the whole grain reportedly stores better than the husked grain (PROSEA, 1996).
