SAMPHIRE; a genus of the digynia order, belonging to the pentandria clas of plants. There are two species, the principal of which is the maritimum, or common maritime samphire. It hath a fibrous penetrating root; thick, succulent, branchy stalks rising two feet high, winged flethy leaves consisting of many small spear-shaped lobes; with round yellow flowers growing in umbels. It is produced naturally on the sea-coasts among the gravel and rocks. Its leaves are an excellent pickle used for sauces, and are by many eaten raw in salads. It is of a saltnish relish, palatable, and comfortable to the stomach. It is not very easily preserved in gardens. It must be sown on gravelly or rocky ground, half an inch deep; in which situation the plants will come up, and last some years. The leaves of this plant are said also to be aperient and diuretic.
