Temporal patterns of Brassicaceae diversification
Huang et al. propose that whole genome duplication events serve as a constant pump for continuous and high species diversification.
Multidirectional evolution of floral chemistry in deceptive Dactylorhiza orchids
Floral chemistry is hypothesized to be the product of natural selection, but researchers have just begun to consider the micro-evolution of these traits.

Phylogeny and genome sizes of Betula
The genus Betula (birches) is widely distributed in the northern hemisphere from the arctic to the tropics. Its woody species are an important component of many ecosystems, and of economic value. The genus was recently...

Evolution of Old World Salvia in Africa
A phylogenetic reconstruction suggests that parallel character evolution is the rule rather than the exception in Old World Salvia in Africa.
Evolutionary history of Afro-Madagascan Ixora
The pantropical genus Ixora is one of the largest genera in Rubiaceae, with approximately 530 species. Tosh et al. conduct phylogenetic analyses based on four plastid and two nuclear ribosomal markers to infer the...
An Australian origin for Drosera meristocaulis
The carnivorous sundew Drosera meristocaulis, which is endemic to a remote high-summit area of the Amazon region, has been shown to share morphological characters with pygmy sundews of Drosera sect. Bryastrum that are...
Molecular phylogenetics of Eurasian Aster
The classification and phylogeny of Eurasian (EA) Aster remain poorly resolved. Li et al. use nrDNA ITS, and ETS and cpDNA trnL-F sequences to delimit EA Aster sensu stricto and to elucidate phylogenetic relationships...
Evolution and biogeography of Plectocephalus
Evolution and biogeography of Plectocephalus The genus Plectocephalus comprises a single species in Ethiopia, two in North America and possibly four more in South America, in a striking disjunction that is exceptional...
Phylogeography and acquisition of dioecy in Malvaceae
In the Mascarenes, a young oceanic archipelago, the Dombeyoideae have extensively diversified and have evolved specific breeding systems compared to the continental species. By constructing a molecular phylogeny, Le...
