(0. Fr. majorane, Med. Lat. majorana; not connected with major, greater, nor with amaracus), in botany, the common name for some aromatic herbs or undershrubs, belonging to the genus Origanum (natural order Labiatae). Wild marjoram is O. vulgare, a perennial common in England in dry copses and on hedge-banks, with many stout stems i to 3 ft. high, bearing short-stalked somewhat ovate leaves and clusters of purple flowers. Sweet or knotted marjoram, O. Marjorana, and pot marjoram, O. Onites, are cultivated for the use of their aromatic leaves, either green or dry, for culinary purposes; the tops are cut as the plants begin to flower and are dried slowly in the shade.
