Sassafras (Lauraceae) consists of three species disjunct between eastern Asia (S. tzumu and S. randaiense) and eastern North America (S. albidum). Phylogenetic analysis based on sequences of nuclear ribosomal ITS and three chloroplast non-coding regions (rpl16, trnL-F, and psbA-trnH) showed that Sassafras is monophyletic and that the eastern North American S. albidum is sister to the clade of its two eastern Asian counterparts. Their intercontinental divergence was estimated to be 13.80 ± 2.29… 
Molecular phylogeny and biogeography of Astilbe (Saxifragaceae) in Asia and eastern North America
The intercontinental disjunct lineage in Astilbe invokes a hybridization event either in eastern Asia or in North America, which provides evidence for the close floristic affinity between temperate or alpine south-western China and tropical Asia.
Molecular phylogenetic analysis of the Persea group (Lauraceae) and its biogeographic implications on the evolution of tropical and subtropical Amphi-Pacific disjunctions.
It is suggested that the Persea group originated from the Perseeae-Laureae radiation in early Eocene Laurasia and can be retained as a genus by the inclusion of Apollonias barbujana and exclusion a few species that do not fit into the established subgenera.
Phylogenetic relationships and biogeographic history of the unique Saxifraga sect. Irregulares (Saxifragaceae) from eastern Asia
Saxifraga L. is the largest genus in Saxifragaceae and a characteristic component of the herbaceous flora of the temperate and alpine mountains in the Northern Hemisphere. Section Irregulares is a
Evolution of floral characters and biogeography of Heloniadeae (Melanthiaceae): an example of breeding system shifts with inflorescence change
A Bayesian phylogenetic tree for Heloniadeae was constructed using cpDNA and inferred the historical biogeography and floral character evolution, revealing that HeloniADEae was distributed in high-latitudes of East Asia and North America, originating since 22.2 mya.
Molecular phylogenetic analysis of Leibnitzia Cass. (Asteraceae: Mutisieae: Gerbera‐complex), an Asian–North American disjunct genus
Molecular phylogenetic analysis of Leibnitzia and other Gerbera‐complex members indicates that LeibNitzia is monophyletic, which is in contrast with the authors' expectation that the American Leib nitzia species L. lyrata and L. occimadrensis would be more closely related to another American member of the GerberA‐complex, namely Chaptalia.
Temporal and Spatial Pattern of Holcoglossum Schltr. (Orchidaceae), an East Asian Endemic Genus, Based on Nuclear and Chloroplast Genes
East Asia is one of the plant diversity and endemism centers in the world, and the temporal and spatial patterns and processes of vascular plants attracted ecologists’ and biogeographers’ attention.
Phylogeny and Historical Biogeography of Asian Pterourus Butterflies (Lepidoptera: Papilionidae): A Case of Intercontinental Dispersal from North America to East Asia
Dating and biogeographic analysis allow us to infer an intercontinental dispersal of an American ancestor of Asian Pterourus in the early Miocene, which was coincident with historical paleo-land bridge connections, resulting in the present “East Asia-America” disjunction distribution.
Characterization of 20 complete plastomes from the tribe Laureae (Lauraceae) and distribution of small inversions
Twenty new, complete plastome sequences are reported including 17 Lindera species and three related species, Actinodaphne lancifolia, Litsea japonica and Sassafras tzumu, indicating that ancient plastomes captures may have contribute to the mixed intergeneric relationship of Laureae.


Monophyly of Kelloggia Torrey ex Benth. (Rubiaceae) and evolution of its intercontinental disjunction between western North America and eastern Asia.
Ancestral area analysis and dispersal-vicariance analysis suggests the Asian origin of Kelloggia and the importance of Eurasia in the diversification of its close relatives in the Rubieae-Theligoneae-Paederieae group.
Phylogeny and biogeography of Altingiaceae: evidence from combined analysis of five non-coding chloroplast regions.
Evolution of biogeographic disjunction between eastern Asia and eastern North America in Phryma (Phrymaceae).
The intercontinental populations of Phryma show distinct molecular divergence with little morphological differentiation, and discordance of the molecular and morphological patterns may be explained by morphological stasis due to ecological similarity in both continents.
Intercontinental biogeography of subfamily Orontioideae (Symplocarpus, Lysichiton, and Orontium) of Araceae in Eastern Asia and North America.
Isozyme divergence between eastern Asian, North American, and Turkish species of Liquidambar (Hamamelidaceae)
Estimates of time of divergence from the isozyme data suggest that the current species diverged before or during the Miocene, and the pattern of relationships portrayed by the iso enzyme data suggest a longer period of separation between the eastern and western Asian forms of this genus.
Historical biogeography and phylogenetic relationships of the genus Chamaecyparis (Cupressaceae) inferred from chloroplast DNA polymorphism
It is suggested that climatic deterioration caused the disappearance of Chamaecyparis in continental Asia is probable and at least two divergence events have produced the eastern Asian, western North American, and both western and eastern North American disjunct distribution in ChamaECy paris.
Molecular divergence between asian and North American species of liriodendron (magnoliaceae) with implications for interpretation of fossil floras
It is indicated that the fossil floras that included, or might have included Liriodendron could not have survived in Beringia after the late Miocene and the onset of southward-migrating Arctic air masses on the North American continent, which suggests a minimum time of separation of approximately 13 million years before present.
Molecular divergence between disjunct taxa in eastern Asia and eastern North America
The results suggest that divergence between the taxa in the four genera are not the result of a single historical event, and the nonconcordant divergences between allozymes and ITS sequences in Menispermum may be caused by concerted evolution in the latter or possibly longer generation time in the woody plants.

Taiwan and Ryukyus constitute an archipelago lying on the western rim of the Pacific Ocean. In contrast to volcanic islands that often arise sequentially, these continental islands emerged almost
