Colonization, levels of speciation and vegetational metamorphosis during ontogeny of
oceanic islands over geological time are central evolutionary and biogeographic concerns …

Traditional classification of speciation modes has focused on physical barriers to gene flow.
Allopatric speciation with complete reproductive isolation is viewed as the most common …

Studies about the drivers of angiosperm clade diversifications have revealed how the
environment continuously alters the species chances to adapt or to go extinct. This process …

Molecular studies have recently led to major changes to the systematics of Boraginaceae
and changed our perception of fruit morphology, previously used as the most important …

Lithospermum (Boraginaceae), a geographically cosmopolitan medium-sized genus,
includes diverse floral morphology, with variation in corolla size and shape and in breeding …

Biogeographic dispersal is supported by numerous phylogenetic results. In particular,
transoceanic dispersal, rather than vicariance, is suggested for some plant lineages despite …

The Irano–Turanian (I–T) bioregion harbours one of the Old World's greatest repositories of
botanical diversity; however, the diversification patterns and the phenotypic evolution of its …

Cynoglossinae with ca. 200 spp. is one of the taxonomically most challenging subtribes of
tribe Cynoglosseae with regard to generic delimitations. Here, we present a phylogenetic …

Recent phylogenetic studies have challenged the traditional classification of the subtribe
Cynoglossinae, which was based on nutlet characteristics. To investigate the evolution of …

We present molecular data demonstrating that the New Zealand endemic Plagiochila
caducifolia represents an isolated population of Plagiochila (sect. Arrectae) spinulosa, a …
