The most primitive family among class Magnoliopsida. It is comprised by woody plants (shrubs and small trees) coming from Easter asia and East shore of northern America. They have quite big simple leaves with petioles. Spiral arrangement of leaves.
Most characteristic trait of that family is the flower.
Despite having quite primitive flowers, Magnoliaceae have wood (xylem) consisting of tracheids, which is the sign of specialisation.
