“…Although the monospe cific African Hypodaphnis Stapf has been considered to be the first branching extant genus of Lauraceae (Rohwer, 2000;Chanderbali & al., 2001;Rohwer & Rudolph, 2005), it could not be included in the present study. However, the Cryptocarya group is closely related to Hypodaphnis and their di vergence times were regarded as very similar (Rohwer, 2000;Chanderbali & al., 2001;Rohwer & Rudolph, 2005;Nie & al., 2007). According to the work of Nie & al.…”

Caryodaphnopsis is a small genus of the Lauraceae. It contains 16 known species with a disjunct tropical amphi‐Pacific distribution; 8 species in tropical Asia and 8 species in tropical America. In the present study, RPB2, LEAFY and ITS sequences of 9 Caryodaphnopsis species and 22 other Lauraceae species were analyzed with maximum parsimony and Bayesian inference. Divergence time estimation employed the Bayesian Markov chain Monte Carlo method under a relaxed clock. Ancestral area reconstructions were conducted by using both the statistical dispersal‐vicariance analysis and likelihood approach under the dispersal‐extinction‐cladogenesis model. Based on the results of the phylogenetic analyses, the monophyly of Caryodaphnopsis is strongly supported. Asian and American Caryodaphnopsis species form two well‐supported monophyletic clades, respectively. Independent lineages for Caryodaphnopsis, Neocinnamomum and Cassytha are also suggested. According to the divergence time estimations and ancestral area reconstructions, we suggest that Caryodaphnopsis originated in Late Cretaceous Laurasia and its amphi‐Pacific disjunction results from the disruption of ancestral boreotropical lineages between Eurasia and North America during the first cooling period of the Eocene.

“…This family radiated when trans-Tethyean migration was relatively easy, and basal lineages were clearly established on the Gondwana or Laurasian terrains by the Late Cretaceous (Renner, 2005). Biogeographic studies suggested that the basal lineages of Lauraceae were sorted into two main geographic groups of Gondwanan or Laurasian origins (Chanderbali et al, 2001;Nie et al, 2007;Li et al, 2011). Scora and Bergh (1992) proposed the western African Gondwanaland flora, probably by Paleocene time, as the place of origin of Persea.…”

Molecular phylogeny and biogeography ofAstilbe(Saxifragaceae) in Asia and eastern North America

et al. 2012

Phylogenetic analyses were conducted for Astilbe (Saxifragaceae), an Asian/eastern North American disjunct genus, using sequences of nuclear ribosomal internal transcribed spacer (ITS) and plastid matK, trnL‐trnF and psbA‐trnH regions. The monophyly of Astilbe is well supported by both ITS and plastid sequences. Topological incongruence was detected between the plastid and the ITS trees, particularly concerning the placement of the single North American species, A. biternata, which may be most probably explained by its origin involving hybridization and/or allopolyploidy with plastid capture. In Astilbe, all species with hermaphroditic flowers constitute a well‐supported clade; dioecious species form a basal grade to the hermaphroditic clade. Astilbe was estimated to have split with Saxifragopsis from western North America at 20.69 Ma (95% HPD: 12.14–30.22 Ma) in the early Miocene. This intercontinental disjunction between Astilbe and Saxifragopsis most likely occurred via the Bering land bridge. The major clade of Astilbe (all species of the genus excluding A. platyphylla) was inferred to have a continental Asian origin. At least three subsequent migrations or dispersals were hypothesized to explain the expansion of Astilbe into North America, Japan and tropical Asian islands. The intercontinental disjunct lineage in Astilbe invokes a hybridization event either in eastern Asia or in North America. This disjunction in Astilbe may be explained by a Beringian migration around 3.54 Ma (95% high posterior density: 1.29–6.18 Ma) in the late Tertiary, although long‐distance dispersal from eastern Asia to North America is also likely. The biogeographical connection between continental Asia, Taiwan, the Philippines and other tropical Asian islands in Astilbe provides evidence for the close floristic affinity between temperate or alpine south‐western China and tropical Asia. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, ●●, ●●–●●.
