Equisetáceas: Diferenzas entre revisións

Tanto a morfoloxía coma as análises moleculares de [[ADN]] (feitos sobre as secuencias [[plastidio|plastídicas]] ''rbcL'', ''trnL-F'', ''rps4'') indican que os fentos e rabos de cabalo son [[monofilético]]s (Pryer ''et al.'' 2001<ref name="Pryer et al. 2001">Pryer, Kathleen M., Harald Schneider, Alan R.
