kingdom - one of seven biological categories: Monera or Protoctista or Plantae or Fungi or Animalia

Thallophyta - used only in former classifications: comprising what is now considered a heterogeneous assemblage of flowerless and seedless organisms: algae; bacteria; fungi; lichens

division Tracheophyta, Tracheophyta - in former classifications: comprising plants with a vascular system including ferns and fern allies as well as seed plants

plant order - the order of plants

Bryophyta, division Bryophyta - a division of nonflowering plants characterized by rhizoids rather than true roots and having little or no organized vascular tissue and showing alternation of generations between gamete-bearing forms and spore-bearing forms; comprises true mosses (Bryopsida) and liverworts (Hepaticopsida) and hornworts (Anthoceropsida)

division Pteridophyta, Pteridophyta - containing all the vascular plants that do not bear seeds: ferns, horsetails, club mosses, and whisk ferns; in some classifications considered a subdivision of Tracheophyta

division Spermatophyta, Spermatophyta - seed plants; comprises the Angiospermae (or Magnoliophyta) and Gymnospermae (or Gymnospermophyta); in some classification systems Spermatophyta is coordinate with Pteridophyta (spore producing plants having vascular tissue and roots) and Bryophyta (spore producing plants lacking vascular tissue and roots)

Phanerogamae - in former classification systems: one of two major plant divisions, including all seed-bearing plants; superseded by the division Spermatophyta

Cryptogamia - in former classification systems: one of two major plant divisions, including all plants that do not bear seeds: ferns, mosses, algae, fungi

plant family - a family of plants

plant genus - a genus of plants

Lycophyta - used in some classifications for the class Lycopsida: club mosses
