Lycophytes and euphyllophytes

WebLycophytes, also known as the ‘fern allies’, are a clade of vascular plants similar to ferns but have unique leaves called microphylls. They are primitive plants and lack seeds, wood, fruit and flowers. As with the ferns, lycophytes produce spores for reproduction and are both wind-pollinated and dispersed.

Web1 feb. 2024 · As both extant lycophytes and euphyllophytes develop roots with caps today, this indicates that roots must have evolved independently in the two lineages … Lycophytes reproduce by spores and have alternation of generations in which (like other vascular plants) the sporophyte generation is dominant. Some lycophytes are homosporous while others are heterosporous. When broadly circumscribed, the lycophytes represent a line of evolution distinct from that leading to all other vascular plants, the euphyllophytes, such as ferns, gymnosperms and flowering plants. They are defined by two synapomorphies: lateral rather than terminal sporangia (often …
