Vascular Plant - Phylogeny

Phylogeny

A proposed phylogeny of the vascular plants after Kenrick and Crane is as follows, with modification to the gymnosperms from Christenhusz et al. (2011a), Pteridophyta from Smith et al. and lycophytes and ferns by Christenhusz et al. (2011b)

Polysporangiates

Tracheophytes
Eutracheophytes
Euphyllophytina
Lignophytes
Spermatophytes

Pteridospermatophyta † (seed ferns)



Cycadophyta (cycads)



Pinophyta (conifers)



Ginkgophyta (ginkgo)



Gnetophyta



Magnoliophyta (flowering plants)




Progymnospermophyta †



Pteridophyta


Pteridopsida (true ferns)



Marattiopsida



Equisetopsida (horsetails)



Psilotopsida (whisk ferns & adders'-tongues)



Cladoxylopsida †





Lycophytina

Lycopodiophyta



Zosterophyllophyta †





Rhyniophyta †





Aglaophyton



Horneophytopsida †



This phylogeny is supported by several molecular studies. Other researchers state that taking fossils into account leads to different conclusions, for example that the ferns (Pteridophyta) are not monophyletic.
