1. In some Christian churches (particularly in the Roman Catholic Church, Anglican Communion, and Lutherans), a person who is appointed to carry the church's processional cross: The crucifer carries a cross or crucifix with a long staff, during processions at the beginning and at the end of the church services.
2. Plants that don't have a permanent woody stem: Many crucifers are flowering garden plants or potherbs; while some of the others have medicinal properties; and then there are some that can be eaten by humans; including, the cabbages, radishes, turnips, and mustards.
