Abstract

Plagiopteron Griff. (Celastraceae), collected from Bac Giang Province of Vietnam is reported here as a new generic record for the flora of Vietnam. It is supposedly an early derived member of the subfamily Hippocrateoideae (composed of tribes Campylostemoneae and Hippocrateeae), within Hippocrateaceae. The genus differs from other members of Celastraceae by its many bicyclically arranged stamens. Leaf anatomical studies have been performed to understand various features such as venation, vascular bundles, collenchyma and stomata. Taxonomic notes, description, and photographs are provided, together with short notes on the distribution, ecology and phenology of the species.Bangladesh J. Plant Taxon. 23(2): 161-166, 2016 (December)

Highlights

The family Celastraceae is represented by 98 genera and 1264 species and distributed across tropics and subtropics, some in temperate regions of the world (Simmons, 2001)
During a recent field work in An Lac Village of Bac Giang Province in Vietnam (Fig. 1), an interesting plant belonging to Celastraceae was collected
Materials and Methods The specimens were collected from the natural habitats, thoroughly processed using standard herbarium techniques (Jain and Rao, 1977) and deposited in Herbarium of Institute of Ecology & Biological Resources (HN) Vietnam and Korea Research Institute of Bioscience & Biotechnology (KRIB)

Summary

Introduction

The family Celastraceae is represented by 98 genera and 1264 species and distributed across tropics and subtropics, some in temperate regions of the world (Simmons, 2001). Critical morphological and anatomical observation, consultation of type specimens and relevant literature studies were carried out and conclusively it was identified as Plagiopteron suaveolens Griff. The genus differs from other members of the family Celastraceae by its many bicyclically arranged stamens.
