Alseodaphnopsis maguanensis and A. putaoensis, two new species of Alseodaphnopsis (Lauraceae) from southwestern China (Yunnan Province) and northern Myanmar (Kachin State), are here described and illustrated based on both morphological and molecular evidence. They are morphologically similar to Alseodaphnopsis rugosa and phylogenetically closely related to A. rugosa and A. hainanensis respectively. Their preliminary conservation status is also estimated according to the IUCN Red List Categories and Criteria.

W. Li & J. Li, gen. nov., separated from Alseodaphne Nees, and a new species Alseodaphnopsis ximengensis H. W. Li & J. Li, sp. nov., endemic to Yunnan province, China. This new species is characterized by having big, axillary, paniculate inflorescences, as well as large, subglobose fruits. Based on DNA sequence data from two gene regions (nuclear ribosomal ITS and LEAFY intron II), we investigate its phylogenetic position within the Persea group. Phylogenies using maximum parsimony (MP) and Bayesian inference (BI) support the recognition of Alseodaphnopsis as a distinct genus but do not resolve well its relationship within the Persea group. The new genus is circumscribed, eight new combinations for its species are made, and a description and illustration of the new species are provided.

Owing to lack of clear-cut morphological differences between genera and species, this family is an ideal case for testing the efficacy of DNA barcoding in the identification and discrimination of species and genera. In this study, we evaluated five widely recommended plant DNA barcode loci matK, rbcL, trnH-psbA, ITS2 and the entire ITS region for 409 individuals representing 133 species, 12 genera from China. We tested the ability of DNA barcoding to distinguish species and as an alternative tool for correcting species misidentification. We also used the rbcL+matK+trnH-psbA+ITS loci to investigate the phylogenetic relationships of the species examined. Among the gene regions and their combinations, ITS was the most efficient for identifying species (57.5%) and genera (70%). DNA barcoding also had a positive role for correcting species misidentification (10.8%). Furthermore, based on the results of the phylogenetic analyses, Chinese Lauraceae species formed three supported monophyletic clades, with the Cryptocarya group strongly supported (PP = 1.00, BS = 100%) and the clade including the Persea group, Laureae and Cinnamomum also receiving strong support (PP = 1.00, BS = 98%), whereas the Caryodaphnopsis-Neocinnamomum received only moderate support (PP = 1.00 and BS = 85%). This study indicates that molecular barcoding can assist in screening difficult to identify families like Lauraceae, detecting errors of species identification, as well as helping to reconstruct phylogenetic relationships. DNA barcoding can thus help with large-scale biodiversity inventories and rare species conservation by improving accuracy, as well as reducing time and costs associated with species identification.

Inflorescence features appear to be among the more reliable morphological characters for explaining relationships between Neolitsea and other genera within the ‘core’ Laureae, with the Neolitsea/Actinodaphne clade defined by inflorescences lacking vegetative terminal buds in the main axis. Although the relationships within Neolitsea are still poorly resolved, there is enough structure to suggest that the genus seems to divide into two groups based on fruit shape: elliptic or ovoid, versus globose, although more evidence (both molecular and morphological) and wider taxon sampling are required to confirm this.

Here we use the fossil-rich Cinnamomum group, a primarily tropical and sub-tropical Asian lineage with some species distributed in Neotropics, Australasia and Africa to shed light upon this disjunction pattern. Phylogenetic and biogeographic analyses were carried out using sequences of three nuclear loci from 94 Cinnamomum group and 13 outgroup samples. Results show that although there are three clades within a monophyletic Cinnamomum group, Cinnamomum and previously recognized subdivisions within this genus were all rejected as natural groups. The Cinnamomum group appears to have originated in the widespread boreotropical paleoflora of Laurasia during the early Eocene (ca. 55 Ma). The formation and breakup of the boreotropics seems to have then played a key role in the formation of intercontinental disjunctions within the Cinnamomum group. The first cooling interval (50–48 Ma) in the late early Eocene resulted in a floristic discontinuity between Eurasia and North America causing the tropical and subtropical amphi-Pacific disjunction. The second cooling interval in the mid-Eocene (42–38 Ma) resulted in the fragmentation of the boreotropics within Eurasia, leading to an African–Asian disjunction. Multiple dispersal events from North into South America occurred from the early Eocene to late Miocene and a single migration event from Asia into Australia appears to have occurred in the early Miocene.
