Phylogenetic relationships based on nuclear and plastid DNA sequences reveal recent diversification and discordant patterns of morphological evolution of the Chilean genera of Gilliesieae (Amaryllidaceae: Allioideae)
Gilliesieae are a South American tribe of Amaryllidaceae characterized by high floral diversity. Given different taxonomic interpretations and proposals for generic and specific relationships, a representative phylogenetic analysis is required to clarify the systematics of this group. The present study provides a framework for understanding phylogenetic relationships and contributing to...Escobar, Inelia ; Ruiz-Ponce, Eduardo ; Rudall, Paula J ; Fay, Michael F ; Toro-Núñez, Oscar …

Geographical structure of genetic diversity in Loudetia simplex (Poaceae) in Madagascar and South Africa
Ecologically dominant species are primary determinants of ecosystem function, especially in grassy ecosystems, but the history and biology of grassy ecosystems in Madagascar are poorly understood compared to those of Africa. Loudetia simplex is a C4 perennial grass that is adapted to fire and common to dominant across Africa. It... -

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 …
