Species integrity and hybridization in anthropomorphic Orchis species (Orchidaceae).
Hybridization is widespread in Orchis (Orchidaceae), with 38 recorded hybrids between the 21 accepted species. The four anthropomorphic Orchis species that occur in Britain (O. anthropophora, O. militaris, O. purpurea and O. simia) are on the edge of their range and are of high conservation priority. Understanding how these species...Bersweden, Leif

Chromosome numbers and heterochromatin variation in introgressed and non-introgressed populations of Epidendrum (Orchidaceae: Epidendroideae): interspecific transfers of heterochromatin lead to divergent variable karyotypes in the parental populations.
Some groups in Epidendrum have stable chromosome numbers, whereas the species of Epidendrum subgenus Amphiglottium exhibit high levels of chromosome number variability and other genomic alterations. Polyploidy and dysploidy have both been invoked to explain chromosome number variation in the subgenus, but little is known about what is driving the...Nollet, Felipe ; Medeiros Neto, Enoque ; Cordeiro, Joel M P ; Buril, Maria Teresa ; Chase, Mark W …

Mediterranean Subspecies versus Californian Varieties: An Example from Acmispon (Leguminosae, Loteae).
The tribe Loteae of the family Leguminosae has major centers of diversity in the Mediterranean Region and California. It is used here to illustrate different traditions of taxonomic interpretation of infraspecific variation among researchers in different continents. Recent accounts of European and Mediterranean taxa commonly make an emphasis on recognizing...Sokoloff, Dmitry D. ; Akulova-Barlow, Zoya V. ; Govaerts, Rafaël

A new hybrid of Origanum (Lamiaceae) from the Aegean Island of Karpathos (Dodecanese, Greece): Origanum × karpathicum.
This study aims to describe a new hybrid of Origanum, which occurs on Karpathos (Greece), by examining its morphology and molecular structure. Nuclear ribosomal DNA (ITS) data of the alleged hybrid specimens, and its putative parents, O. onites and O. vetteri, were examined. Hybrid and parent individuals sharing the same...Cattaneo, Cristina ; Dimarchou, Theocharoula ; Özcan, Taner ; Dirmenci, Tuncay

Estimation of species divergence times in presence of cross-species gene flow.
Cross-species introgression can have significant impacts on phylogenomic reconstruction of species divergence events. Here, we used simulations to show how the presence of even a small amount of introgression can bias divergence time estimates when gene flow is ignored in the analysis. Using advances in analytical methods under the multispecies...Tiley, George P ; Flouri, Tomás ; Jiao, Xiyun ; Poelstra, Jelmer W. ; Xu, Bo …
