Angiospermae

The itis.gov database lists two entries for Kingdom Plantae:
  1. Angiospermae – not accepted.
  2. Angiospermae – accepted – angiosperma, angiospermes, angiosperms, flowering plants.
"The flowering plants. Seed plants in which the ovules are enclosed in a carpel (in all but a very few genera), and the seeds at maturity are born within fruits. They are extremely diverse vegetatively but characterized by the flower, which is basically insect-pollinated. Other modes of pollination, such as wind pollination, have been derived in a number of different lines. The gametophytes are much reduced, with the female gametophyte often consisting of only eight cells or nuclei at maturity. Double fertilization involving two of the three nuclei from the mature microgametophyte gives rise to the zygote and to the primary endosperm nucleus; the former becomes the embryo and the latter a special nutritive tissue, the endosperm. Among the pterophytes, multicellular archegonia characterize all gymnosperms except for two genera of the class Gnetinae. There are about 250,000 species."
