First insights on the biogeographical history of Phlegmariurus (Lycopodiaceae), with a focus on Madagascar
We explored the biogeographical history of a group of spore-bearing plants focusing on Phlegmariurus (Lycopodiaceae), a genus of lycophytes comprising ca. 250 species. Given its wide distribution in the Southern Hemisphere, Phlegmariurus provides a good model to address questions about the biogeogra...

We explored the biogeographical history of a group of spore-bearing plants focusing on Phlegmariurus (Lycopodiaceae), a genus of lycophytes comprising ca. 250 species.
