A tropical plant cultivated in many warm

countries for the sake of its seeds, known as physic nuts. The

juice of the plant, which is milky, acrid, and glutinous, produces

an indelible brown stain on linen. The oil from the seeds is used

oxide of iron and used as a varnish. It is also used medicinally.
