Ethnomedical information and Pharmacognostical investigations of Rhaphidophora pertusa Schott. (Araceae), a lesser known, but promising wild medicinal plant are discussed in the paper.

New work suggests ‘subgenome dominance' in polyploids may only occur angiosperms. Subgenome dominance could explain angiosperm-specific genome reduction, with potential implications for angiosperms' global dominance. I suggest that evolution of the endosperm have selected subgenome dominance, due to increased hybrid/polyploid incompatibilities and/or through direct reciprocal suppression matern...

Aim To examine the biogeographical history of the angiosperm clade Caprifolieae (Caprifoliaceae) using parametric biogeographical reconstruction methods. The existing parametric method was extended to evaluate biogeographical reconstructions over the distribution of dated phylogenies. This method provides a framework for reconstructing large-scale biogeography with parametric methods, while acc...

To explain the rise of angiosperms during the Cretaceous, Berendse & Scheffer (Ecol. Lett., 12, 2009, 865) invoke feedbacks between leaf litter, soil nutrients, and growth, overlooking other factors affecting resource acquisition by Cretaceous plants. We evaluate their hypothesis, highlight alternative explanations, and emphasize use of a broader framework for understanding the angiosperm radia...
