Despite the broad acceptance of phylogenetic principles in biological classification, a
fundamental question still exists on how to classify paraphyletic groups. Much of the …

Background Although the overwhelming majority of genes found in angiosperms are
members of gene families, and both gene-and genome-duplication are pervasive forces in …

The temperate bamboos are a morphologically diverse grass lineage with a complex and
problematic taxonomy. We present the first robust multilocus chloroplast phylogeny of the …

Puya (Bromeliaceae), a large genus of terrestrial bromeliads found throughout a range of
elevations in the Andes and central Chile, is of great systematic, evolutionary, and …

• Premise of the study: The monogeneric family Ruppiaceae is found primarily in brackish
water and is widely distributed on all continents, many islands, and from subartic to tropical …

Reseda sect. Glaucoreseda is a monophyletic group composed of five endemic tetraploid
species with a disjunct distribution in the high mountains and plateaus of the Iberian …

Noncoding chloroplast DNA sequences are widely employed markers in plant species–level

The repeated formation and loss of land‐bridges during the Pleistocene have had lasting
impacts on population genetic structure. In the tropics, where island populations persisted …

Instances of hybridization between mammalian taxa in the wild are rarely documented. To
