A Taxonomic Revision of Styppeiochloa (Arundinoideae: Poaceae) in Madagascar.
The grass genus Styppeiochloa De Winter (Arundinoideae: Poaceae) as it occurs in Madagascar is reviewed, two new species are described, and two subspecific taxa are elevated to species status. These new species, as well as the additional collections made since the latest treatment of the genus for Madagascar in 1954,... -

Global variation in diversification rate and species richness are unlinked in plants.
Species richness varies immensely around the world. Variation in the rate of diversification (speciation minus extinction) is often hypothesized to explain this pattern, while alternative explanations invoke time or ecological carrying capacities as drivers. Focusing on seed plants, the world’s most important engineers of terrestrial ecosystems, we investigated the role...Tietje, Melanie ; Antonelli, Alexandre ; Baker, William J. ; Govaerts, Rafaël ; Smith, Stephen A. …

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... -

Diversity, Endemism, and Evolutionary History of Montane Biotas Outside the Andean Region
Mountain ranges are important centers of biodiversity around the world. This high diversity is the result of the presence of different soil types and underlying bedrock, a variety of micro-climatic regimes, high topographic heterogeneity, a heterogeneous and complex vegetation cline, and a dynamic geo-climatic history. Neotropical research on mountains has...
