OverviewAI-generated

Spermatophytes, also referred to as phanerogams, constitute a taxonomic subdivision within the plant kingdom. This group is classified under the parent taxa of tracheophyte, Euphyllophyta, Lignophyta, and Polysporangiophytes. The taxon has been described in the Brockhaus and Efron Encyclopedic Dictionary. Common names for this group include plante à graines, 種子植物, and semenovke.

The lineage of seed plants dates back to approximately 319 million years ago. While the iNaturalist database lists a specific entry with the rank of species and the common name American plantain, this entry is not marked as extinct. The broader taxon is referenced by 786 other encyclopedia articles.

A spermatophyte (lit. 'seed-bearing plants'; from Ancient Greek σπέρματος (spérmatos) 'seed', and φυτόν (phytón) 'plant'), also known as phanerogam (taxon Phanerogamae) or phaenogam (taxon Phaenogamae), is any plant that produces seeds, hence the alternative name seed plant. Spermatophytes are a subset of the embryophytes or land plants. They include most familiar types of plants, including all flowering plants and gymnosperms, but exclude some other types of plants such as ferns, mosses, and algae. The term phanerogams or phanerogamae is derived from the Greek φανερός (phanerós), meaning "visible", in contrast to the cryptogamae (from Ancient Greek κρυπτός (kruptós) 'hidden'), together with the suffix γαμέω (gaméō), meaning "to marry". These terms distinguished those plants with hidden sexual organs (cryptogamae) from those with visible sexual organs (phanerogamae).

Encyclopedic overview

A seed plant or spermatophyte (from Ancient Greek σπέρμα (spérma) 'seed' and φυτόν (phutón) 'plant'; lit. 'seed plant'), also called a phanerogam (taxon Phanerogamae) or a phaenogam (taxon Phaenogamae), is any plant that produces seeds. It is a category of embryophyte (i.e. land plant) that includes most of the familiar land plants, including the flowering plants and the gymnosperms, but not ferns, mosses, or algae.

The term phanerogam or phanerogamae is derived from Ancient Greek φανερός (phanerós), meaning "visible", in contrast to the term "cryptogam" or "cryptogamae" (from Ancient Greek κρυπτός (kruptós) 'hidden', and γαμέω (gaméō), 'to marry'). These terms distinguish those plants with hidden sexual organs (cryptogamae) from those with visible ones (phanerogamae).
