683C10EDD0B15F76AE83357D95885DB0.taxon	diagnosis	Diagnosis. Carpinus wenshanensis is morphologically and phylogenetically most closely allied to C. tschonoskii, yet exhibits diagnostic differences in six key characteristics: leaf margin serration (mucronate versus setiform), serrate position on outer bract margin (restricted to the basal half versus extending across both basal and apical halves), fewer serration numbers on outer bract margin (1 – 3 versus 4 – 7 serrations per bract), pubescent density of leaf petiole and annual branchlet (nearly glabrous versus sparse or dense), petiole length (1.0 – 1.7 versus 0.6 – 1.3 cm), and leaf base morphology (rounded, subrounded, cordate, or subcordate versus rounded-cuneate or cuneate).	en	Zhou, Xiao-Long, An, Qian-Na (2025): Carpinus wenshanensis (Betulaceae), a new species from southeast Yunnan, China.

683C10EDD0B15F76AE83357D95885DB0.taxon	description	Description. Trees to 11 m tall; bark gray with shallow vertical fissures. Branchlets gray-brown, glabrous, with prominent white to yellowish-white lenticels. Leaves: petiole 1.0 – 1.7 cm, nearly glabrous; blade elliptic, oblong, or ovate-lanceolate, 5.4 – 9.2 × 2.8 – 4.2 cm (length-to-width ratio 1.9 – 2.8); abaxial surface sparsely villous along veins, bearded in axils of lateral veins, adaxial surface glabrous; base rounded, subrounded, cordate, or subcordate; apex acute, acuminate, or caudate; margin irregularly or doubly mucronate-serrate; lateral veins 11 – 14 pairs. Inflorescences 5.5 – 8.5 × 3.0 – 4.5 cm; peduncle 1.5 – 3.0 cm, sparsely villous. Bracts semiovate- to ovate-lanceolate, loosely imbricate, 2.2 – 3.1 × 0.7 – 1.0 cm, adaxially sparsely pubescent; outer margin with 1 – 3 serrations restricted to the basal half, lacking basal lobe; inner margin entire, bearing an inflexed basal lobe (1.0 – 2.0 mm); apex acute or acuminate; primary veins 3 – 4 (excluding inflexed lobe), venation prominent. Nutlets broadly ovoid, 4.0 – 5.0 × 3.5 – 4.5 mm, sparsely to densely pubescent, villous at apex, sparsely resinous-glandular, prominently ribbed.	en	Zhou, Xiao-Long, An, Qian-Na (2025): Carpinus wenshanensis (Betulaceae), a new species from southeast Yunnan, China.

683C10EDD0B15F76AE83357D95885DB0.taxon	etymology	Etymology. To date, this hornbeam is known only from a single population in Wenshan Prefecture. Given its apparently restricted endemic status and limited distribution, we have chosen the specific epithet wenshanensis to reflect its geographic origin.	en	Zhou, Xiao-Long, An, Qian-Na (2025): Carpinus wenshanensis (Betulaceae), a new species from southeast Yunnan, China.
