<i>Carpinuswenshanensis</i> (Betulaceae), a new species from southeast Yunnan, China.

ABSTRACT: Carpinuswenshanensis Xiaolong Zhou, a newly discovered hornbeam species endemic to Wenshan Prefecture in southeast Yunnan, China, is described and illustrated. This study employs an integrative taxonomic approach, combining morphological comparison, biogeographic distribution analysis, and phylogenetic reconstruction based on nuclear ITS sequences, to establish C.wenshanensis as a distinct species sister to C.tschonoskii. Carpinuswenshanensis is diagnostically characterized by six key morphological traits: (1) mucronate-serrate leaf margins (versus setiform serrate in C.tschonoskii); (2) serration restricted to the basal half of outer bract margins (versus extending across both basal and apical halves); (3) reduced serration number on outer bract margins
