Cladistics of the Spermatophyta
@article{Loconte2008CladisticsOT, title={Cladistics of the Spermatophyta}, author={H. Loconte and D. Stevenson}, journal={Brittonia}, year={2008}, volume={42}, pages={197-211} }
A cladistic interpretation of seed plant phylogeny is presented that supports the traditional morphological hypothesis: [Cycadales-(Ginkgoales-(Coniferales-(Gnetales-Angiosperms)))]. Gnetales and Angiosperms are supported as sister groups of theAnaspermae. A sister-group relationship between Coniferales and Ginkgoales represents a paraphyletic group, because Coniferales and Anaspermae share a common ancestry (Mesospermae). Ginkgoales and Mesospermae are sister groups of theCladospermae… Expand
