Chloroplast DNA phylogeny, reticulate evolution, and biogeography of Paeonia (Paeoniaceae).
A refined hypothesis of species phylogeny of section Paeonia was proposed by considering the discordance between the nuclear and cpDNA phylogenies to be results of hybrid speciation followed by inheritance of cpDNA of one parent and fixation of ITS sequences of another parent.
Documentation of reticulate evolution in peonies (Paeonia) using internal transcribed spacer sequences of nuclear ribosomal DNA: implications for biogeography and concerted evolution.
Reconstruction of reticulate evolution with sequence data provides gene records for distributional histories of some of the parental species and demonstrates that the sequence data could be highly informative and accurate for detecting hybridization.
Phylogenetic relationships in subfamily Tillandsioideae (Bromeliaceae) based on DNA sequence data from seven plastid regions.
Results of the combined data set clearly show that subfamily Tillandsioideae is monophyletic, and the earliest divergence separates a lineage comprised of Glomeropitcairnia and Catopsis from the "core" tillandsioids.
Radiation of the endemic genus Dendroseris (Asteraceae) on the Juan Fernandez Islands: evidence from sequences of the its regions of nuclear ribosomal DNA
Phylogenetic relationships among nine of the 11 species of the endemic genus Dendroseris on the Juan Fernandez Islands were inferred from nucleotide sequences of the internal transcribed spacer regions (ITS) of the 1 8-26S nuclear ribosomal DNA, supporting the hypothesis of rapid adaptive radiation of DENDroser is on the islands.
Botanical and Geological Significance of Potassium-Argon Dates from the Juan Fern�ndez Islands
Potassium-argon dating of five basalts from the Juan Fern�ndez Islands of Chile gives ages that are consistent with the origin of the island-seamount chain from a mantle hot spot beneath the eastward moving Nazca plate and suggests that speciation within endemic genera has occurred within the past 4 to 5 million years.
ITS Sequences and the Phylogeny of the Genus Robinsonia (Asteraceae)
ITS sequences provide strong support for the monophyly of Robinsonia, and relative rate tests indicate that the molecular clock cannot be rejected for ITS sequence evolution in Robinsonia.
Phylogenetics of tribe Phyllantheae (Phyllanthaceae; Euphorbiaceae sensu lato) based on nrITS and plastid matK DNA sequence data.
Phylogenetic relationships within tribe Phyllantheae, the largest tribe of the family Phyllanthaceae, were examined with special emphasis on the large genus Phyllanthus, and taxonomic divisions based on similar pollen morphology are confirmed, and related taxa share similar distributions.

The second edition of this popular resource reflects these far-reaching and dramatic developments with more than 3,000 new references and many new figures and provides the most up-to-date overview in relation to monographic, biodiversity, and evolutionary studies.
Allozyme diversity in endemic flowering plant species of the Juan Fernandez Archipelago, Chile: ecological and historical factors with implications for conservation.

High mean G(ST) values for the species examined illustrate the need for conserving as many populations as possible, either in the wild or in the garden, to preserve maximal diversity within species.
