A novel 2-stage Markov chain Monte Carlo (MCMC) method that first obtains independent Bayesian posterior probability distributions for individual genes using standard methods and introduces a one-parameter probability distribution to describe the prior distribution of concordance among gene trees.

It is shown that the oaks are phylogenetically overdispersed because co‐occurring species are more distantly related than expected by chance, and oaks within the same clade show less niche overlap than expected.
Concordance trees, concordance factors, and the exploration of reticulate genealogy
- D. Baum

It is argued that a primary concordance tree, a tree built from clades that are true of a plurality of the genome, provides a useful summary of the dominant phylogenetic history for a group of organisms.

There has been extensive homoplasy in characters previously used to delineate major taxonomic groups in core Malvales, and it is suggested that /Malvatheca do not have as a synapormophy monothecate anthers, as has been previously supposed but, instead, may be united by dithecate, transversely septate (polysporangiate) anothers.
Phylogenetics of the genus Scaevola (Goodeniaceae): implication for dispersal patterns across the Pacific Basin and colonization of the Hawaiian Islands.

Analyses of ITS sequence data demonstrate that Scaevola is a monophyletic group if S. collaris is excluded and Diaspasis filifolia is included, and indicates that three of the six dispersals established species on the remote Hawaiian Archipelago, representing at present the largest number of colonizations by any flowering plant genus to these islands.
Biogeography and floral evolution of baobabs (Adansonia, Bombacaceae) as inferred from multiple data sets.
The phylogeny does not permit unambiguous reconstruction of floral evolution but suggests the plausible hypothesis that hawkmoth pollination was ancestral in Adansonia and that there were two parallel switches to pollination by mammals in the genus.

The Tree-Thinking Challenge
It has become apparent that trees are commonly misunderstood, leading to confusion about the concept of common ancestry, and tree thinking should be taught as an element of evolution training at all levels.
Floral Gigantism in Rafflesiaceae
Results of phylogenetic analyses of mitochondrial, nuclear, and plastid data showing that Rafflesiaceae are derived from within Euphorbiaceae, the spurge family are presented, suggesting that the enormous flowers of RFFlesiaceae evolved from ancestors with tiny flowers.
