Angiosperms , in the phylum Anthophyta , are the most successful phylum of plants. This category also contains the largest number of individual plants ( Figure below ). Angiosperms evolved the structure of the flower, so they are also called the flowering plants. Angiosperms live in a variety of different environments. A water lily, an oak tree, and a barrel cactus, although different, are all angiosperms.
