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.

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.

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.

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.

New contributions to the flora of Myanmar Ⅰ.

In this study, we describe several new taxa belonging to the flora of Myanmar. One new family, Polyosmaceae ( Benn.) is recorded.

(Orchidaceae, Epidendroideae, Arethuseae), a new species from Chin State, Myanmar.

, a new species of section Proliferae, from Natma Taung (Mt.Victoria) National Park, Chin State, Myanmar, is described and illustrated. It is morphologically similar to , but the clustered pseudobulbs, pure brownish- red flowers and column wing with irregular notches at the apex of the new species differ from the other species.

(Lamiaceae, Premnoideae), a remarkable new species from north Myanmar.

A remarkable new species from Myanmar, Y.H.Tan & Bo Li (Lamiaceae), is here described and illustrated.

(Zingiberaceae), a new species from Putao, Kachin State, Northern Myanmar.

(Orchidaceae, Dendrobieae), a new species from Kachin State, Myanmar.

, a new species from Naungmung, Kachin State, North Myanmar, is described and illustrated. It is morphologically similar to and , but the epichile is oblong with three long-ciliate laminae and the column wing has significant denticulation. A preliminary risk-of-extinction assessment shows that the new species should be regarded as Critically Endangered (CR) according to the IUCN Red List Categories and Criteria.

(Aristolochiaceae), a new species from north Myanmar.

Y.H.Tan & B.

Two new species of (Annonaceae) from northern Myanmar.

and , two new species of Annonaceae from Putao, Kachin State, Myanmar, are here described and illustrated. They are morphologically similar to and . The major differences between them are outlined and discussed.

(Orchidaceae), a new species from northern Myanmar.

(Orchidaceae), a new species from Putao, Kachin State, Myanmar, is described and illustrated. It belongs to Coelogyne section Ocellatae Pfitzer & Kraenzl. and it is morphologically similar to and , but can be distinguished from these species by its larger flowers, lanceolate sepals and petals, a narrowly ovate lip, which has two bright yellow patches surrounded by shiny brownish red and two fimbriate or erose-lacerate lateral keels on the lip.
