Premise of research. The disjunct distribution of plant genera between eastern Asia (EA)
and eastern North America (ENA) has long attracted the attention of biologists and …

Phylogenetic analyses using diverse datasets can yield conflicting inference of evolutionary
history. Phylogenetic conflicts observed in both animal and plant systems have often been …

Stewartia is a genus of approximately 26 species which are frequently divided into two
subgenera or genera based on the leaf duration. All evergreen species (= Hartia) are found …

Informed species delimitation is crucial in diverse biological fields; however, it can be
problematic for species complexes. Showing a peripatric distribution pattern, Stewartia …

Although eastern Asia (EAS) and eastern North America (ENA) have similar climates, plant
species richness in EAS greatly exceeds that in ENA. The degree to which this diversity …

The eastern Asian (EAS)‐eastern North American (ENA) floristic disjunction is one of the
best‐known biogeographic patterns in the Northern Hemisphere. Recent paleontological …

Despite several morphological and molecular analyses of Theaceae, several outstanding
issues remain in the phylogenetics and biogeography of the family including the disputed …

The underlying causes of biodiversity disparities among geographic regions have long been
a fundamental theme in ecology and evolution. However, the patterns of phylogenetic …

Abstract Tribe Stewartieae (Theaceae) consists of evergreen Hartia and deciduous
Stewartia. Pollen morphology was investigated using light and scanning electron …

Comparative approaches that examine floras with similar environments, but different
diversity patterns, provide good opportunities to elucidate how uneven distributions of …
