TAILIEUCHUNG - Agapetes guangxiensis D. Fang, a new record for the flora of Vietnam
Agapetes guangxiensis D. Fang, previously known only from China, is reported here as a new record for the flora of Vietnam. This species was found in Dien Bien and Ha Giang provinces of North Vietnam. It differs from the allied species, A. rubrobracteata, in having leaf blades ovate with serrate margins, inflorescence barcts smaller (c. mm long) and ecalcarate anthers. | TAP CHIguangxiensis SINH HOC 2015, 37(3): 296-299 Agapetes D.

Fang, previously known only from China, is reported here as a new record for the flora of Vietnam. This species was found in Dien Bien and Ha Giang provinces of North Vietnam. It differs from the allied species, A. rubrobracteata, in having leaf blades ovate with serrate margins, inflorescence barcts smaller (c. mm long) and ecalcarate anthers. Information on the taxonomy, type, ecology and distribution is provided for A. guangxiensis. The vouchers are housed at the herbarium of the Institute Ecology and Biological Resources, Ha Noi, Vietnam (HN). A key to the nine species of Agapetes in Vietnam is provided. Keywords: Agapetes, A. guangxiensis, Ericaceae, New record, Dien Bien, Ha Giang, Vietnam. INTRODUCTION Agapetes D. Don ex G. Don with ca. 100 species, belongs to the family Ericaceae under subfamily Vaccinioideae Arn. and tribe Vaccinieae Rchb. [1]. The genus is distributed principally from the East Himalayas through South-West China and Indochina to South-East Asia [2]. Until now Agapetes was considered to be represented in Vietnam by eight species and they were taxonomically studied by several authors [3, 4]. However, during our botanical surveys, an interesting Agapetes species was encountered at Ha Giang and Dien Bien provinces of North Vietnam. These specimens were characterized by having small ovate leaves with serrate margin, hirsute calyx tube and short white
