In botany, a neophyte is a plant species which is non-native to a geographical region, and was introduced in recent history. The term is derived from the Greek neo = new and phytos = plant. Archaeophytes are plants that are long-established in an area and are considered to have been first introduced prior to 1492, when Christopher Columbus arrived in the Americas and the Columbian Exchange 1 began.
