Streptophytina is formally a subdivision or subphylum (but sometimes used at the division level, where more appropriate would be the use of the term Streptophyta, see below) which contains two classes: Charophyceae, containing the Charales order (Charophytes sensu stricto); and Embryophyceae, which contains the embryophytes (land plants, bryophytes, and vascular plants). Plants are living Organisms belonging to the kingdom Plantae. Charophyceae is a Taxon of Green algae whose exact rank is the matter of some current debate The Charales are Algae in the division Charophyta. They are green plants believed to be the closest relatives of the green land plants. The Charophyta are a division of Green algae, including the closest relatives of the Embryophyte plants The embryophytes are the most familiar group of Plants They include Trees Flowers Ferns Mosses and various other green The embryophytes are the most familiar group of Plants They include Trees Flowers Ferns Mosses and various other green The embryophytes are the most familiar group of Plants They include Trees Flowers Ferns Mosses and various other green Bryophytes are all Embryophytes ('land Plants) that are non-vascular: they have tissues and enclosed reproductive systems but they lack Vascular tissue Vascular plants (also known as tracheophytes or higher plants) are those Plants that have lignified tissues for conducting
The term streptophyta, formally a term for a division or phylum, is also used to indicate a subkingdom and used to include land plants (embryophytes) as well as several orders of green algae (class Charophyceae) previously included in the division Charophyta. Charophyceae is a Taxon of Green algae whose exact rank is the matter of some current debate The Charophyta are a division of Green algae, including the closest relatives of the Embryophyte plants [1]

Polysporangiophytes are plants with a structure of branching axes terminating in sporangia. The embryophytes are the most familiar group of Plants They include Trees Flowers Ferns Mosses and various other green Vascular plants (also known as tracheophytes or higher plants) are those Plants that have lignified tissues for conducting The spermatophytes (from the Greek word "Σπερματόφυτα" (also known as phanerogams) comprise those Plants that produce Seeds They are Pteridospermatophyta, also called seed ferns, is an extinct Spermatophyte group of the Plantae kingdom. Cycads are a group of Seed plants characterized by a large crown of compound leaves and a stout trunk. The Ginkgoaceae is a family of Gymnosperms which appeared during the Mesozoic Era of which the only extant representative is Ginkgo biloba The Plant division Gnetophyta or gnetophytes comprise three related families of Woody plants grouped in the Gymnosperms The gnetophytes differ from The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group A fern is any one of a group of about 20000 Species of Plants classified in the phylum or division Pteridophyta, also known as Filicophyta The Pteridopsida is a class of Plants in the Division Pteridophyta that includes all the Leptosporangiate ferns In the recent 2006 classification by Class Marattiopsida is a group of Ferns containing a single order Marattiales, and family Marattiaceae. Equisetopsida, or Sphenopsida, is a class of Plants with a fossil record going back to the Devonian. Psilotopsida is a class of Fern -like plants As circumscribed by Smith et al The cladoxylopsids are a group of Plants known only as Fossils that are thought to be ancestors of Ferns and Horsetails They had a central trunk The Division Lycopodiophyta (sometimes called Lycophyta) is a tracheophyte subdivision of the Kingdom Plantae It is the oldest extant (living The Zosterophyllaceae or Zosterophylls (class Zosterophyllopsida) were probably Stem-group Lycophytes forming a sister group to the ancestors Rhyniophyta is a division of early Vascular plants including the class Rhyniopsida.
