Biogeography and genome size evolution of the oldest extant vascular plant genus, Equisetum (Equisetaceae)
Abstract Background and Aims Extant plant groups with a long fossil history are key elements in understanding vascular plant evolution. Horsetails (Equisetum, Equisetaceae) have a nearly continuous fossil record dating back to the Carboniferous, but their phylogenetic and biogeographic patterns are still poorly understood. We use here the most extensive...Christenhusz, Maarten J M ; Chase, Mark W ; Fay, Michael F ; Hidalgo, Oriane ; Leitch, Ilia J …

Extensive plastid-nuclear discordance in a recent radiation of Nicotiana section Suaveolentes (Solanaceae)
Nicotiana section Suaveolentes is the largest section of Nicotiana and is a monophyletic group of allotetraploid species. Most of the species are endemic to Australia, but three species occur on islands in the South Pacific as far east as French Polynesia and one species is native to Namibia. Here, we...
