Taxonomic notes on Pistacia cucphuongensis (Anacardiaceae) with its new distribution record in China

A comprehensive morphological and taxonomic revision of the imperfectly known species, Pistacia cucphuongensis (Anacardiaceae), is presented. Previously only recorded from Vietnam, this species is newly reported from China in this study. The floral morphology of P. cucphuongensis is described for the first time based on observations of living plants in the field and herbarium specimens. A complete list of examined specimens, a distribution map, and a colour plate are provided. Additionally, the conservation status of this species is assessed, and a detailed comparison with the morphologically similar P. weinmannifolia is included.
