Angiosperms

Medical Definition: Any member of the more than 250,000 species of flowering plants. Angiosperms are often differentiated from GYMNOSPERMS by their production of seeds within a closed chamber (OVARY, PLANT). The Angiosperms division is composed of two classes, the monocotyledons (Liliopsida) and dicotyledons (Magnoliopsida).
