Abstract. We reconstructed phylogenies of populations of three closely related species of Spigelia (Loganiaceae sensu lato) to test hypotheses about relationships and taxonomic boundaries. The species studied occur in the southeastern U.S. with a disjunction in their distribution along the Gulf Coastal plain between Florida and Texas. Two sets of data, restriction sites of cpDNA and ITS sequences, were analyzed. We found three well-supported clades of cpDNA types that correspond to previous… 

Phylogeny and Biogeography of the Eastern North American Rose Gentians (Sabatia, Gentianaceae)

TLDR
Phylogenetic analyses reveal that aSabatia + Gyrandra clade diverged in the late Middle Miocene, with Sabatia subsequently splitting into western and eastern Gulf Coast clades during the early Late Miocene.

A Toxic Story: Phylogeny and Classification of Strychnos L. (Loganiaceae)

TLDR
Most of the 12 well-supported clades within Strychnos are restricted to specific continents, sometimes with limited dispersion between neighboring continents, suggesting a history of repeated cross-oceanic dispersal or vicariance patterns.

Spigelia genuflexa (Loganiaceae), a new geocarpic species from the Atlantic forest of northeastern Bahia, Brazil

TLDR
A phylogenetic parsimony and Bayesian analysis of ITS sequences from 15 Spigelia species plus 17 outgroups in Loganiaceae confirms its independent taxonomic status: on the basis of sequence similarity and phylogenetic topology it is phylogenetically distinct from all Spigilia species sequenced so far.

A re-evaluation of North American Tephroseris and Sinosenecio (Asteraceae: Senecioneae) based on molecular and micromorphological data

TLDR
Molecular sequence data from the ITS region of nuclear ribosomal DNA and micromorphological data from anther endothecial cells that indicate S. newcombei is closely related to North American Tephroseris species are provided.

Deep divergences in the coffee family and the systematic position of Acranthera

TLDR
Nuclear ITS provided structured information at all phylogenetic levels, but the main gain from adding nrITS was the increased resolution and average support values also increased but were generally high also without nr ITS and the increase was not statistically significant.

EXAMINING GENETIC STRUCTURE IN A BOGUS YUCCA MOTH: A SEQUENTIAL APPROACH TO PHYLOGEOGRAPHY

TLDR
It is suggested that performing a suite of analyses that focus on different temporal scales may be an effective approach to investigating the patterns and causes of genetic structure within species.
