Popis: | This paper lists the evolutionary advances that Psilophyton (Trimerophytina) shows over the simplest vascular plants like Cooksonia and Rhynia (Rhyniophytina). Both morphological and anatomical (using Psilophyton dawsonii, the only completely petrified example) advances are treated. Similarly Psilophyton is shown to be less advanced than some groups presumed to be derivatives of trimerophytes. Evolution within the genus Psilophyton and within Trimerophytina is discussed briefly. |
