   a species of the genus myrtus, especially myrtus
   communis. the common myrtle has a shrubby, upright stem,
   eight or ten feet high. its branches form a close, full head,
   thickly covered with ovate or lanceolate evergreen leaves. it
   has solitary axillary white or rosy flowers, followed by
   black several-seeded berries. the ancients considered it
   sacred to venus. the flowers, leaves, and berries are used
   variously in perfumery and as a condiment, and the
   beautifully mottled wood is used in turning.
