Molecular phylogeny of Urvillea (Paullinieae, Sapindaceae) and its implications in stem vascular diversity
<ul> <li>Background and Aims: The tribe Paullinieae have the highest diversity of vascular variants among the seed plants. The developmental diversity is better understood in the speciose genera <em>Paullinia </em>and <em>Serjania, </em>however, the phylogeny and diversity of vascular variants in the smaller genera of Paullinieae remain understudied. Here we investigate the evolution of development of stem vasculatures in the small genus <em>Urvillea.</em></li> <li>Methods: We generate the first molecular phylogeny of <em>Urvillea </em>derived from 11 markers using a maximum likelihood and Bayesian approach. In combination with phylogenetic reconstruction, stochastic character mapping is used to assess evolutionary changes in stem ontogenies, determined from developmental anatomy of stems collected in the field or from herbarium and wood collections. </li> <li>Key Results: <em>Urvillea </em>is supported as a monophyletic group and sister to <em>Serjania. </em>There are five stem ontogenies in <em>Urvillea, </em>including a regular anatomy and four vascular variants. Most stem ontogenies initiate with lobed stems. Lobed adult stems are conserved in <em>Urvillea</em>, but this ontogeny was lost multiple times. A reversal to regular anatomy occurred in non-climbing species. Phloem wedges, fissured stems and ectopic cambia evolved independently once. Phloem wedges is an intermediate developmental stage in the formation of fissured stems, which is characterized by a continuous fragmentation of vascular tissues. Lobed stems may generate constriction zones and lobes may split or not. </li> </ul> <ul> <li>Conclusions: <em>Urvillea </em>stands out as the third most diverse genus in number of vascular variants within Paullinieae, but only one ontogeny (fissured stems) is exclusive for the genus. Differential cambial activity and ectopic cambia are the main ontogenetic processes generating stem diversity. The evolutionary history of vascular variants demonstrates the large developmental lability of the cambium in such a small genus and corroborates a scenario of repeated evolution of complex anatomies within Paullinieae lianas.</li> </ul>

Population genetics under the Massenerhebung effect: the influence of topography on the demography of Acer morrisonense (Sapindaceae)
<p><span>Aim: </span><span><span>The Massenerhebung effect (Mass elevation effect) refers to heat or wind-driven altitudinal distribution patterns of temperature-dependent parameters among massifs with narrower range and lower elevation around peripheral and isolated mountains compared to core and continuous ones. Although common in ecology, this effect is rarely discussed in population genetics. Here, we use genetic markers to reveal population genetic patterns and also test the mountain- and sky-barrier hypotheses relevant to the Massenerhebung distribution pattern of <i>Acer morrisonense</i> in Taiwan's rugged topography and varied local climates.</span></span></p> <p><span>Location: </span><span><span>The alpine and cloud forest of Taiwan. </span></span></p> <p><span>Taxon: </span><span><i>Acer morrisonense </i>Hayata</span></p> <p><span>Methods: </span><span><span>Two chloroplast DNA (cpDNA) fragments and 17 <span>expressed sequence tag-simple sequence repeat (</span>EST-SSR) loci respectively from 200 and 286 individuals were used to elucidate the phylogeographic pattern of pollen and seed dispersal of <i>A. morrisonense</i>. These data were combined with ecological niche modeling (ENM) to infer distribution range shifts and refugia. We also correlated the genetic-divergence indices with spatial factors to clarify latitudinal and altitudinal effects on genetic diversity.</span></span></p> <p><span>Results: </span><span><span>The incongruent phylogeographic patterns of genetic distributions between nuclear and cpDNA markers indicate unhindered pollen flow but spatially constrained seed dispersal. Taken together with ENM, the genetic pattern further reflects historical colonization from central-mountain refugia to edges since the Holocene. The Massenerhebung reduces the gene flow by the surrounding mountains and also causes lower genetic diversity compared to central alpine populations.</span></span></p> <p><span>Main conclusions</span>: This study is the first to reveal the influence of Massenerhebung effect on cpDNA genetic structure of montane trees and reflect the spatial trends of seed dispersal. This population genetic pattern can also be attributed to the demography-related range shifts with paleoclimate fluctuations under complex mountain topography, supporting the mountain-barrier hypothesis. The results have important implications for conserving the genetic diversity of species with a wide altitudinal distribution range.</p>

Data from: Two new species of Serjania (Sapindaceae) from Michoacán, Mexico, with notes on S. biternata
Serjania rosalindae and S. crucensis (Sapindaceae-Paullinieae), new species from the municipality of La Huacana, Michoacán, Mexico, are described, illustrated, and compared with closely related species. In addition, micromorphological features of the leaves, flowers, and pollen grains are investigated. A treatment of the endemic S. biternata from Guerrero is also included because it is a little-known taxon similar to S. rosalindae whose fruits were previously unknown. All of these taxa share capsules that are chartaceous to almost woody and septifragal, a fruit type otherwise uncommon within Serjania. The distinctive fruit morphology of these species is discussed in relation to other species of Serjania.
