Sper`ma*toph"y*ta, n. pl. [NL.; spermato- + Gr. plant.] (Bot.)
Definition: A phylum embracing the highest plants, or those that produce
seeds; the seed plants, or flowering plants. They form the most
numerous group, including over 120,000 species. In general, the group
is characterized by the marked development of the sporophyte, with
great differentiation of its parts (root, stem, leaves, flowers,
etc.); by the extreme reduction of the gametophyte; and by the
development of seeds. All the Spermatophyta are heterosporous;
fertilization of the egg cell is either through a pollen tube emitted
by the microspore or (in a few gymnosperms) by spermatozoids. The
phrase "flowering plants" is less distinctive than "seed plants,"
since the conifers, grasses, sedges, oaks, etc., do not produce
flowers in the popular sense. For this reason the terms Anthrophyta,
Phænogamia, and Panerogamia have been superseded as names of the
phylum by Spermatophyta.
