Spermatophyte
The spermatophytes (from the Greek word "Σπερματόφυτα"), also known as phanerogams or phenogamae, comprise those plants that produce seeds, hence the alternative name seed plants. They are a subset of the embryophytes or land plants. The term phanerogams or phanerogamae is derived from the Greek φανερός, phaneros = "visible", in contrast to the cryptogamae from Greek κρυπτός kryptos = "hidden" together with the suffix γαμέω, gameein, "to marry". These terms distinguished those plants with hidden sexual organs (cryptogamae) from those with visible sexual organs (phanerogamae).
Description
The living spermatophytes form five groups:
cycads, a subtropical and tropical group of plants with a large crown of compound leaves and a stout trunk,
Ginkgo, a single living species of tree,
conifers, cone-bearing trees and shrubs,
gnetophytes, woody plants in the genera Ephedra, Gnetum, and Welwitschia
angiosperms, (or magnoliophyta) the flowering plants, a large group including many familiar plants in a wide variety of habitats.
