Leek, or Allium porrum, L. a well-known vegetable, the native place of which is at present unknown, though it has long been cultivated in Britain.
The leaves of this plant possess a flavour similar to that of onions; affording a constant dish at the tables of the Egyptians, who chop . them small, and eat them with their meat. They are also in great esteem among the Welch; and their general utility as a wholesome pot-herb, renders them a valuable culinary spice. — For the proper method of cultivating the leek, see Onion.
