Gymnosperms (Gymnospermae) are a group of seed-bearing plants with ovules borne on the edge or blade of an open sporophyll, the sporophylls usually arranged in cone-like structures. The other major ...

Here we discuss recent advances surrounding the origin of angiosperms. Putatively primitive characters are now much better understood because of a vastly improved understanding of angiosperm ...

Named for Charles Darwin, the only known specimen of a newly discovered beetle, Darwinylus marcosi, died in a sticky gob of tree sap some 105 million years ago in what is now northern Spain. As it ...

Plant-insect interactions, one of the critical bedrocks for modern ecosystems, are largely dominated by insect-angiosperm relationships owing to the hegemony enjoyed by flowering plants since the Late ...

Trees are typically organized into two categories: hardwoods (angiosperms) and softwoods (gymnosperms). A new study suggests that there is a third type of wood—known as “midwood”—that could explain ...

High-throughput sequencing is fundamentally altering traditional phylogenetic classifications. While the Angiosperm Phylogeny Group (APG) III system based on chloroplast sequences has opened up a new ...

Wall ultrastructure of fossil-dispersed pollen has recently played an important role in increasing our understanding of the origin and early evolution of angiosperms. The criteria currently used to ...
