Cob-nut

Cob-nut, a name given to some of the largest and finest cultivated varieties of the Hazel-nut (q.v.).—In the West Indies the name cob-nut is given to the fruit of Omphalea triandra, a tree of the natural order Euphorbiaceæ. It is also called Hog-nut. The tree has a white juice, which turns black in drying, and in Guiana is used instead of ink. The albumen of the seed is eaten, after the embryo, which contains a cathartic principle, is removed.
