“…These age priors conform to the 95% highest posterior density (HPD) interval of corresponding nodes inferred in a study of the Asterids and Gentianales divergence times by Wikström et al (2015). The Morindeae stem lineage age prior is also supported by fossil evidence, specifically by the occurrence of Morinda chinensis in the early Late Eocene (38 Ma) of China (Shi et al, 2012). The BEAST analysis comprised two independent runs, each including 100 × 10 6 generations sampling trees and parameters every 10,000th generation.…”

This study reinforces the pivotal role of dispersal in shaping the WIOR biodiversity and as the critical initiating step in the generation of endemic biodiversity on its islands. The WIOR alliance shows strong Asian and Pacific affinities despite the proximity of the region to Africa. Madagascar has served as a stepping-stone for subsequent dispersal to the rest of the region. The Afro-Malagasy-Seychelles genus Craterispermum and the Malagasy Puffia may represent relictual lineages.

“…This fossil has a head-shaped infructescence (multiple fruits or syncarps), which is developed from a capitu-lum composed of about 20-30 flowers, the fruits of which are fused into one unit (Shi et al, 2012), and these characters fit well with Morinda. Shi et al (2012) argued that, based on its shape and number of simple fruits of the infructescence, the fossil fruit should be placed in Morinda section Roioc DC. However, the authors also point out that its infructescence contains fewer simple fruits than other species of this section.…”

“…Morinda chinensis Shi, Liu & Jin was recently described as a well‐preserved fossil dated back to the late early to the early late Eocene (Shi et al ., ).

Molecular phylogenetics and biogeography of the eastern Asian-eastern North American disjunctMitchellaand its close relativeDamnacanthus(Rubiaceae, Mitchelleae)

Mitchella is a small genus of the Rubiaceae with only two species. It is the only herbaceous semishrub of the family showing a disjunct distribution in eastern Asia and eastern North America, extending to Central America. Its phylogeny and biogeographical diversification remain poorly understood. In this study, we conducted phylogenetic and biogeographical analyses for Mitchella and its close relative Damnacanthus based on sequences of the nuclear internal transcribed spacer (ITS) and four plastid markers (rbcL, atpB‐rbcL, rps16 and trnL‐F). Mitchella is monophyletic, consisting of an eastern Asian M. undulata clade and a New World M. repens clade. Our results also support Michella as the closest relative to the eastern Asian Damnacanthus. The divergence time between the two intercontinental disjunct Mitchella species was dated to 7.73 Mya, with a 95% highest posterior density (HPD) of 3.14−12.53 Mya, using the Bayesian relaxed clock estimation. Ancestral area reconstructions suggest that the genus originated in eastern Asia. The semishrub Mitchella appears to have arisen from its woody ancestor in eastern Asia and then migrated to North America via the Bering land bridge in the late Miocene. © 2013 The Linnean Society of London

Fossil leaves of Nelumbo changchangensis, collected from the Eocene of Hainan Island, China, were studied and compared with those of the extant species of Nelumbo, N. nucifera Gaertn. and N. lutea Willd. The fossil leaves have all the specialized features of extant Nelumbo in leaf architecture, except that the organization of the areolae looks much more irregular than that of extant Nelumbo. Comparisons of the cuticle and epicuticular ultrastructure indicate that: (1) N. changchangensis resembles N. nucifera in that anticlinal cell walls of the lower epidermis are straight along the major veins and near leaf bases and are shallowly undulate with U‐ to V‐shaped undulations inside the areolae; (2) N. changchangensis differs from N. lutea in that anticlinal cell walls of the lower epidermis of the latter are deeply undulate with U‐, V‐ to reversed Ω‐shaped undulations inside the areolae; and (3) epicuticular wax crystals are more densely distributed on the leaves of N. changchangensis and N. nucifera than they are in N. lutea. These findings shed significant light on the cuticle differentiation of fossil and extant Nelumbo species. The morphometric comparisons indicate that almost all the synapomorphies of extant Nelumbo were already present by the Eocene, © 2015 The Linnean Society of London, Botanical Journal of the Linnean Society, 2016, 180, 123–137.
