horneophytopsida造句

• For the cladogram, see the Horneophytopsida article.
• The earliest diverging polysporangiophytes in the cladogram are the Horneophytopsida, a clade at the'protracheophyte'grade that is sister to all other polysporangiophytes.
• In 2004, Crane et al . published a cladogram for the polysporangiophytes in which the Horneophytopsida are shown as the sister group of all other polysporangiophytes.
• Cladistic analysis suggests that the genus may belong to the Horneophytopsida, a class of the polysporangiophytes, as it lacks vascular tissue and has branched stems bearing sporangia.
• As the sporangia of " Tortilicaulis " are branched, cladistic analysis suggests that the genus may instead belong to the Horneophytopsida, a class of the polysporangiophytes, which unlike bryophytes, have branched stems bearing sporangia.
• One other former rhyniophyte, " Aglaophyton ", is also placed outside the tracheophyte clade, as it did not possess true vascular tissue ( in particular did not have tracheids ), although its conducting tissue is more complex than that of the Horneophytopsida.
