TL;DR: DArT is a demonstrably valuable addition to the set of existing molecular approaches used to infer biological phenomena such as adaptive radiations, population dynamics, hybridization, introgression, ecological differentiation and phylogeography.

TL;DR: Comparative morphological study reveals that all heterosporous ferns bear indusiate sori on a branched, nonlaminate structure that is referred to as the sorophore; this expanded definition highlights homology previously obscured by the use of different terms.

TL;DR: Inferring the evolution of epiphytism in extant ferns shows that diversification of major living epipHYtic groups mostly occurred in the Tertiary, and focuses on the Hymenophyllaceae family which provides an original example of hygrophilousEpiphytic strategy that is unique in vascular plants.

TL;DR: The phylogenetic results provided new evidence for the sectional classification of Lepisorus and unique character combinations, rather than synapomorphies, were found to be of systematic value in sectional delimitation.

TL;DR: A phylogeny for all extant species of the heterosporous fern genus Azolla is presented here based on more than 5000 base pairs of DNA sequence data from six plastid loci, in agreement with other recent molecular phylogenetic hypotheses that support the monophyly of sections Azolla and Rhizosperma and the proposed relationships within section Azolla.
