WebFeb 26, 2016 · Lycophyte roots appear earlier in the fossil record than those of euphyllophytes ( Boyce, 2005; Raven and Edwards, 2001) and several authors have suggested that they evolved from aerial stems or axes ( Stewart and Rothwell, 1993; Gensel and Berry, 2001; Gensel et al., 2001; Seago and Fernando, 2013 ). WebLycophytes, comprising the groups historically known as the lycopsids and zosterophylls, have the longest history of any group of vascular land plants. The early evolution of the group is reviewed concentrating on the Late Silurian and Devonian record of Lycopsida and Zosterophyllopsida.
