原生地・分布（英語）:

説明（英語）: Genus of about 5 species of monoecious, annual or perennial, often rhizomatous grasses, originating in E. Asia but widely naturalized in tropical regions throughout the world. The leaves are flat and narrowly lance-shaped. Coix species produce compound inflorescences, borne in the upper leaf axils, which consist of many racemes of separate male and female spikelets. Female flowers of C. lacryma-jobi, the only species commonly cultivated, produce hard, bead-like seeds, which are frequently used in the manufacture of rosaries. The teardrop-like shape of the seeds gives rise to the common names, Christ’s or Job’s tears. C. lacryma-jobi may be grown outdoors in both warm-and cool-temperate climates. It is suitable for an annual border or for infilling in a herbaceous border.

耐寒性（英語）: Half hardy.
