Wu (Rubiaceae), previously known only from China, is newly recorded from Vietnam. A morphological description and color illustrations, morphological comparison of Acranthera sinensis with Acranthera siamensis, together with short notes, map on the distribution, ecology, habitat and conservation of the species are provided. Keywords: Rubiaceae, Acranthera, A. sinensis, new record, Vietnam. INTRODUCTION is provided (table 1). This species Acranthera sinensis C. Y. Wu, under the family Rubiaceae, was so far known to be endemic to China, according to the Chen. T., et al [1]. During a field trip to the Ha Giang province (North Vietnam), an interesting species of Rubiaceae was encountered. Hence, we report this species as a new distributional record to the flora of Vietnam, with a single population found in the primary broad-leaved evergreen closed forest, nearby waterfall, in Ha Giang province, not common in the studied areas. More extensive field surveys are needed to find more Acranthera sinensis populations that probably exist somewhere in similar habitats in the studied areas. This work will provide insight for conservation and management of rare and threatened plant species in Vietnam. The taxonomic description and color photographs, distribution, ecology, phenology and conservation of the species are provided to facilitate its easy identification (fig. 1, fig. 2). This species is morphologically most similar to Acranthera siamensis (Kerr) Bremek, in having erect subshrub to 1 m tall, leaves membranaceous, elliptic to obovate. However, this species
