A new species, Callicarpa bachmaensis Soejima & Tagane, sp. nov., is described and illustrated from Bach Ma National Park in Thua Thien Hue Province, Central Vietnam. This species has a characteristic liana habit, white corolla, and narrowly elliptic to narrowly lanceolate, entire, occasionally subequal leaves, by which it is clearly distinguished from the other previously known species of this genus.

Introduction

The genus Callicarpa L. (Lamiaceae) comprises 154 species and 12 varieties (The Plant List 2013) of shrubs or small trees, rarely woody climbers, distributed in temperate and tropical regions. The center of species diversity of this genus is in the Old World, especially in Malesia where about 50 species occur (Bramley 2013). Common and well-known species are found widely in secondary forests or in disturbed areas, but many species are restricted to small areas in primary forest (Bramley 2009, 2013). The genus is characterized by simple, opposite leaves, small white to pink or violet flowers in cymose or thyrsoid infloresences, small globose drupes, and often stellate, plumose, or dendroid hairs on stems, leaves, calyces, and fruits (Chen and Gilbert 1994, Bramley 2009, 2013, Leeratiwong et al. 2009).

The species of Vietnam have been studied by de Loureiro (1790), Dop (1935), Ho (2003), and most recently by Phuong (2007) who enumerated 20 species. During a botanical survey of Bach Ma National Park in Thua Thien Hue Province, Central Vietnam in 2015, we found a species that was different from all the other known species of Callicarpa. This plant is described and illustrated as a new species, Callicarpa bachmaensis Soejima & Tagane.
