Abstract:  Agapetes nana (Griff.) Hook. f. is reported as a newly recorded species of Ericaceae from China for the first time, which is previously known only from northeast India and north Myanmar. It is special and differs from its congeners by its distinct palisade of gland-tipped hairs which forms a sort of epicalyx at the base of calyx tube and corolla tube lobed to 2/3 with conspicuous reflexed lobes. A detailed description, a colour plate and taxonomic notes on the species were provided. Additionally, the morphology of its mature flowers is described for the first time. The voucher specimen is kept in the herbarium of Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences (HITBC).
Key words:  Ericaceae  Agapetes  A. nana  New record
