Early lycophyte evolution
Did you know?
WebNov 30, 2016 · The evolution of rooting structures was a crucial event in Earth's history, increasing the ability of plants to extract water, mine for nutrients and anchor above-ground shoot systems. Fossil evidence indicates that roots evolved at least twice among vascular plants, in the euphyllophytes and independently in the lycophytes. Within the broadly defined lycophyte group, species placed in the class Lycopodiopsida are distinguished from species placed in the Zosterophyllopsida by the possession of microphylls. Some zosterophylls, such as the Devonian Zosterophyllum myretonianum, had smooth stems (axes). Others, such as Sawdonia ornata, had flap-like extensions on the stems ("enations"), but with…

WebThe earliest evidence of true leaves is in fossil lycophytes, as narrow elongated leaves called microphylls. Microphylls, also termed lycophylls, are quite different from the euphyll, or megaphyll, leaves of the euphyllophytes ( Gifford and Foster, 1989; Pryer et al., 2004 ).
