(Rubiaceae), a new species from south-western China and northern Vietnam.

, a new species from south-western China and northern Vietnam, is described and illustrated. The new species is characterised by the glabrous surfaces on almost all plant parts, congested inflorescences and broad-ovate to ovate bracts 9-22 × 4-11 mm. It morphologically differs from the closest species, , mainly in most plant parts being glabrous, bracts broad-ovate to ovate, apex acute or sometimes obtuse, corollas inside with a ring of white hairs at the middle and anthers inserted near the middle in long-styled flowers.

Comparative analyses of eight complete plastid genomes of two hemiparasitic vines in the family Lauraceae.

Splitting one species into 22: an unusual tripling of molecular, morphological, and geographical differentiation in the fern family Didymochlaenaceae (Polypodiales).

The pantropical fern genus Didymochlaena (Didymochlaenaceae) has long been considered to contain one species only. Recent studies have resolved this genus/family as either sister to the rest of eupolypods I or as the second branching lineage of eupolypods I, and have shown that this genus is not monospecific, but the exact species diversity is unknown. In this study, a new phylogeny is reconstructed based on an expanded taxon sampling and six molecular markers.

Two new species of (Annonaceae) based on morphological characters and phylogenetic evidence, with a supplementary description of from China.

Two new species of (Annonaceae), Y.H. Tan & Bin Yang from Guangxi and Yunnan Provinces and Y.

 (Acanthaceae), a new species from Guangxi, China.

, a new species of Acanthaceae from Guangxi, China is described and illustrated. This new species belongs to Rungiasect.Rungia, and resembles and in the erect perennial herbaceous habit, elliptic leaves and inflorescence form, but differs mainly by the indumentum and the morphology of the bracts and corolla.

Two new species from Sulawesi and Borneo facilitate phylogeny and taxonomic revision of (Juglandaceae).

, a genus of Juglandaceae (the walnut family), is endemic to tropical and subtropical Asia. The rich Cenozoic fossil records and distinctive morphological characters of the living plants have been used to explore the evolutionary history and geographic distribution of Juglandaceae. However, the taxonomy of this genus has been suffered from a lack of in-depth investigation and good specimens across its distribution ranges.

Plastid genome evolution of a monophyletic group in the subtribe Lauriineae (Laureae, Lauraceae).

, a non-monophyletic group of the tribe Laureae (Lauraceae), plays important roles in the tropical and subtropical forests of Asia, Australia, Central and North America, and the islands of the Pacific. However, intergeneric relationships between and , , and of the tribe Laureae remain unresolved. In this study, we present phylogenetic analyses of seven newly sequenced plastomes, together with 47 Laureae plastomes obtained from public databases, representing six genera of the Laureae.

Opening a door to the spatiotemporal history of plants from the tropical Indochina Peninsula to subtropical China.

The complexity of global biodiversity in the tropical Indochina Peninsula and subtropical China bioregions has fascinated biologists for decades, but little is known about the spatiotemporal patterns in these regions. Accordingly, the aims of present study were to investigate the evolutionary and distribution patterns of Engelhardia in these regions and establish a model for examining biogeographic patterns and geological events throughout the tropical Indochina Peninsula and subtropical China. The effects of geological events occurring in the area between the Indochina Peninsula and subtropical China bioregions on the two trees species (i.

A new isotope framework to decipher leaf-root nitrogen allocation and assimilation among plants in a tropical invaded ecosystem.

Exotic plant invasion is an urgent issue occurring in the biosphere, which can be stimulated by environmental nitrogen (N) loading. However, the allocation and assimilation of soil N sources between leaves and roots remain unclear for plants in invaded ecosystems, which hampers the understanding of mechanisms behind the expansion of invasive plants and the co-existence of native plants. This work established a new framework to use N concentrations and isotopes of soils, roots, and leaves to quantitatively decipher intra-plant N allocation and assimilation among plant species under no invasion and under the invasion of Chromolaena odorata and Ageratina adenophora in a tropical ecosystem of SW China.

(Annonaceae), a new species from Yunnan, China.

sp. nov. (Annonaceae) is described from Yunnan Province in Southwest China.

Contributions to the flora of Myanmar from 2000 to 2019.

Myanmar is botanically rich and floristically diverse: one of the world's biodiversity hotspots. However, Myanmar is still very unevenly explored, and until a plant checklist was published in 2003, relatively little work was done on its flora. This checklist included 11,800 species of spermatophytes in 273 families.

Shining a light on species delimitation in the tree genus Engelhardia Leschenault ex Blume (Juglandaceae).

Enhanced efficacy in species delimitation is critically important in biology given the pending biodiversity crisis under global warming and anthropogenic activity. In particular, delineation of traditional classifications in view of the complexity of species requires an integrative approach to effectively define species boundaries, and this is a major focus of systematic biology. Here, we explored species delimitation of Engelhardia in tropical and subtropical Asia.

From to (Annonaceae): transfer of species enlarges a previously monotypic genus.

The genus Chaowasku (Annonaceae) was a poorly known monotypic genus from Vietnam that was recently segregated from the highly polyphyletic genus s.l. The sister clade relationship between and was not well established in previous study.

Notes on the genus (Orchidaceae) in Myanmar.

Myanmar is known for its high species richness of genus ; however, most of them lack proper information for taxonomic revision. During four years of field investigation in Myanmar, two new distributional records were encountered, namely, and and one species, i.e.

Exceptionally high rates of positive selection on the rbcL gene in the genus Ilex (Aquifoliaceae).

Background: The genus Ilex (Aquifoliaceae) has a near-cosmopolitan distribution in mesic habitats from tropical to temperate lowlands and in alpine forests. It has a high rate of hybridization and plastid capture, and comprises four geographically structured plastid groups. A previous study showed that the plastid rbcL gene, coding for the large subunit of Rubisco, has a particularly high rate of non-synonymous substitutions in Ilex, when compared with other plant lineages.
