A plural or taxonomic group term referring to primitive seed-bearing plants or organisms with archisperms.
Plural form of archisperm or Latin-based botanical group name, using the Latin feminine plural -ae ending. Formed in 19th-century botanical classification systems.
This is the kind of word that shows how scientists loved formal Latin names—archispermae sounds like an ancient plant family, but it's basically botanists' way of saying 'the original seed-makers' to organize their evolutionary tree.
