A phylum comprising the flowering plants (angiosperms). The gametes are produced within flowers and the ovules (and the seeds into which they develop) are enclosed in a carpel (compare Coniferophyta). The angiosperms are the dominant plant forms of the present day. They show the most advanced structural organization in the plant kingdom, enabling them to inhabit a very diverse range of habitats. There are two classes within this group: the Monocotyledoneae with one seed leaf (cotyledon) in the seed, and the Dicotyledoneae with two seed leaves.
