The Subkingdom Viridaeplantae is a member of the Kingdom Plantae. Here is the complete "parentage" of Viridaeplantae:

The Subkingdom Viridaeplantae is further organized into finer groupings including:

Phyla

[ Back to top ]

Bryophyta

(Gr. bryon: moss; phyton: plant) A phylum of simple plants possessing no vascular tissue and rudimentary rootlike organs (rhizoids). They grow in a variety of damp habitats, from fresh water to rock surfaces. Some use other plants for support. Mosses show a marked alternation of generations between gamete-bearing forms (gametophytes) and spore-bearing forms (sporophytes): they possess erect or prostrate leafy stems (the gametophyte generation, which is haploid); these give rise to leafless stalks bearing capsules (the sporophyte generation, which is diploid), the latter being dependent on the former for water and nutrients. Spores formed in the capsules are released and grow to produce new plants. Formerly, this phylum also included the liverworts and hornworts, now regarded as separate phyla (see Hepatophyta; Anthocerophyta) and the mosses were classified as a class (Musci) of the Bryophyta. The term 'bryophytes' is still used informally to refer to members of all three phyla. Syn. Bryopsida. [more]

Charophyta

See Charophyceae. [more]

Chlorophyta

Chlorophyta, a division of , includes about 7000 species[1] of mostly aquatic photosynthetic eukaryotic organisms. Like the land plants (bryophytes and tracheophytes), green algae contain chlorophylls a and b, and store food as starch in their plastids. They are related to the Charophyta and Embryophyta (land plants), together making up the Viridiplantae. [more]

Magnoliophyta

The flowering plants or angiosperms (Angiospermae or Magnoliophyta) are the most diverse group of . The flowering plants and the gymnosperms are the only extant groups of seed plants. The flowering plants are distinguished from other seed plants by a series of apomorphies, or derived characteristics. [more]

Tracheophyta

(L. trachia: windpipe, trachea; Gr. phyton: plant) A division of plants comprising green plants with a vascular system that contains tracheids or tracheary elements, being the Pteridophyta and Spermatophyta, commonly called vascular plants. [more]

At least 720,692 species and subspecies belong to the Phylum Tracheophyta.
