Ninety-three new combinations in Euploca for species of Heliotropium section Orthostachys (Boraginaceae sensu APG)
Many new combinations are needed in Euploca, previously regarded as Heliotropium section Orthostachys, to correspond with results of our forthcoming, world-wide, molecular phylogenetic analysis. We also need these names for our many δ13C determinations that identify many Euploca species exhibiting C4 photosynthesis and show that other Euploca species are not...Frohlich, Michael W. ; Thulin, Mats ; Chase, Mark W.

Repetitive DNA Restructuring Across Multiple Nicotiana Allopolyploidisation Events Shows a Lack of Strong Cytoplasmic Bias in Influencing Repeat Turnover
Allopolyploidy is acknowledged as an important force in plant evolution. Frequent allopolyploidy in Nicotiana across different timescales permits the evaluation of genome restructuring and repeat dynamics through time. Here we use a clustering approach on high-throughput sequence reads to identify the main classes of repetitive elements following three allotetraploid events,... -

Too many species: morphometrics, molecular phylogenetics and genome structure of a Brazilian species complex in Epidendrum (Laeliinae; Orchidaceae) reveal fewer species than previously thought
In this study, we analyse a species complex in Epidendrum, a mega-diverse Neotropical orchid genus, that is formed by the 11 Brazilian species of the E. difforme group. Although this group (c. 100 taxa) exhibits relatively high levels of floral variation, the Brazilian species are similar, making delimitation problematic. Here... -
