The evolutionary history of the Arabidopsis arenosa complex: diverse tetraploids mask the Western Carpathian center of species and genetic diversity. [PDF]

PLoS ONE, 2012
The Arabidopsis arenosa complex is closely related to the model plant Arabidopsis thaliana. Species and subspecies in the complex are mainly biennial, predominantly outcrossing, herbaceous, and with a distribution range covering most parts of latitudes ...

Leptochilus dolichophyllus (Polypodiaceae), a New Hemiepiphytic Species From Fujian, China [PDF]

Ecology and Evolution
A new species, Leptochilus dolichophyllus (Polypodiaceae), from central‐northern Fujian, southeastern China, is described and illustrated. It is morphologically similar to Leptochilus leveillei, but differs by its hemiepiphytic habit and longer frond ...
