A new Permian gnetalean cone as fossil evidence for supporting current molecular phylogeny.

Abstract

BACKGROUND AND AIMS The order Gnetales has been the central focus of controversy in seed plant phylogeny. Traditional treatment of morphology supports the anthophyte hypothesis with Gnetales sister to angiosperms but current molecular data reject this hypothesis. A new fossil gnetalean cone, Palaeognetaleana auspicia gen. et sp. nov., is reported from the… (More)
