“…2, 3), especially for the basal Lauraceae lineages. As in several earlier studies (Chanderbali & al., 2001;Rohwer & Rudolph, 2005;Wang & al., 2010), Caryodaphnopsis is monophyletic (Fig. 2), sup porting the combination of opposite leaves, strongly unequal tepals, distinctive wood and bark anatomy as generic charac ters (Van der Werff & Richter, 1996).…”

“…the Neotropics. Based on recent molecular studies (Chanderbali & al., 2001;Rohwer & Rudolph, 2005;Wang & al., 2010), 22 species of Neocinnamomum, Cassytha, the Cryptocarya group and core Lauraceae were selected as the outgroups (Appen dix 1). Total genomic DNA was extracted either from field collected (silicagel dried) or herbarium leaf material using the Plant Genomic DNA Kit (Tiangen, Beijing, China).…”

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.

“…12C-E). According to recent molecular systematic evidence, Caryodaphnopsis is closely related to Neocinnamomum (Rohwer and Rudolph, 2005;Wang et al, 2010). As a result, we hypothesized that the dome-like elevation of epidermal cells in Neocinnamomum represents a transitional form between the regular flat lower leaf epidermis in most Lauraceae and the double layered epidermis of Caryodaphnopsis.…”

“…The double-layered lower leaf epidermis of Caryodaphnopsis is distinct in the family, and forms an autapomorphic character of the genus. This unique combination of characters partially accounts for the phylogenetic position of Caryodaphnopsis in the family, the genus alone or together with Neocinnamomum are sister to the core Laureae (Rohwer, 2000;Chanderbali et al, 2001;Rohwer and Rudolph, 2005;Wang et al, 2010).…”

“…In addition to the big phylogeny of the Lauraceae [23]–[24], a few molecular systematic studies were conducted on Lauraceae to discuss the generic relationships, e.g. Litsea complex [25]–[27], Neolitsea [26]–[28], Neocinnamomum [29]–[30], Actinodaphne [26]–[27], [31], and Persea group [32]–[33], but the Beilschmiedia group was poorly sampled. For the Beilschmiedia group in the Tropical East Asia ( Beilschmiedia , Sinopora , Syndiclis , and Endiandra ), it is difficult to separate Endiandra and Syndiclis from Beilschmiedia .…”

Beilschmiedia turbinata: A Newly Recognized but Dying Species of Lauraceae from Tropical Asia Based on Morphological and Molecular Data

China took great efforts to reforestation, even turned the long-term forest loss into a net gain, but this cannot hide the loss of species diversity due to destruction of primary forests, habitat loss, invasion of alien species, and over exploitation. Here we provide such a case by recording a dying tree species of Lauraceae from the evergreen forests of SE Yunnan of China and adjoining Vietnam. We made field collections and observations for four consecutive years from 2009 to 2012. Phylogenetic analyses were conducted based on a combined dataset from nrITS and plastid trnL-trnF region, rpl16 intron, and psbA-trnH spacer. The results indicate that the Asiatic Beilschmiedia and Syndiclis are reciprocally monophyletic with Endiandra as a sister group, and both morphology and molecular phylogeny clearly suggest that the new species belongs to Beilschmiedia. Thus Beilschmiedia turbinata Bing Liu et Y. Yang is illustrated and described as new to science, color plates, line drawings, distribution map and comparison with related species are provided. This new species is similar to B. yunnanensis in the small and ferruginous-brown tomentose terminal buds, elliptic to oblong-lanceolate and alternate or subopposite leaves bearing the fine veinlet reticulation, but differs from the latter by the smaller flowers, the eglandular stamens of the third whorl, and the large turbinate furfuraceous fruits.
