  1. Polysporangiophyte

    Spore-bearing plants

    Polysporangiophytes, also called polysporangiates or formally Polysporangiophyta, are plants in which the spore-bearing generation has branching stems that bear sporangia. The name literally means 'many sporangia plant'. The clade includes all land plants except for the bryophytes whose sporophytes are normally unbranched, even if a few exceptional cases occur. While the definition is independent of the presence of vascular tissue, all living polysporangiophytes also have vascular tissue, i.e., are vascular plants or tracheophytes. Extinct polysporangiophytes are known that have no vascular tissue and so are not tracheophytes. Wikipedia

    Exhibit apical branching in their sporophytes (spore-bearing phase of lifecycle). Branching allows for multiple sporangia per plant, therefore the name polysporangiophyte or "many sporangia plant". This is in contrast to the bryophytes, which have one sporangium per individual since their sporophytes do not branch.

    Horneophyton corms found in the Rhynie chert; scale bar is 1 cm.. The Horneophytopsida, informally called horneophytes, are a class of extinct plants which consisted of branched stems without leaves, true roots or vascular tissue, found from the Late Silurian to the Early Devonian (around ).They are the simplest known polysporangiophytes, i.e. plants with sporophytes bearing many spore-forming ...
