Type:— VIETNAM. Hanamninh [now Ninh Binh Province]: Cuc Phuong, 10 January 1963, Tan Ban Nguyen 948( holotype HN, HN0000001291!).
Description:—Shrubs 1.5–3 mtall. Branchlets gray-white to dark gray, densely lenticellate. Leaves paripinnate (rarely impari-pinnate) with (5)6–12 subopposite or rarely alternate leaflets; petiole 5–9 cmlong, base slightly swollen, together with rachis and petiolules often white-pruinose and pubescent; rachis adaxially centrally ridged, apex with an extension; leaflets opposite or subopposite, subleathery, oblong, oblong-lanceolate, or subrhombic, 3.8–10 × 2–3.5 cmwide, adaxially glabrous except the pubescent midveins, abaxially pubescent, base obliquely cuneate, apex obtuse or retuse; midvein adaxially impressed, abaxially raised; lateral veins 5–8 pairs, branching and anastomosing near margin; minor veins inconspicuous; petiolules robust, 2–3 mmlong. Dioecious. Inflorescences axillary panicles, 4–5 cmlong; rachis pubescent, sparsely so apically; inflorescence base with 2 large leathery bracts; branches dense, each branch with a bract; bracts externally gray-white tomentose; flowers small, purple-red, shortly pedicellate, pedicel ca. 0.5 mm; bracteole 1, ovate, concave, ca. 1.3 mmlong, dorsally pubescent apically and marginally. Male flowers: tepals 5–7, ovate-triangular, ca. 0.5 mmlong, apex acute, with a few to several long soft hairs; stamens 4–7; filaments very short; anthers short-cylindric, purple-red, 1–1.5 mmlong, apex with a protruding connective; sterile pistil present. Female flowers: tepals similar to male flowers; staminodes absent; ovary globose, glabrous; style very short; stigma 3-lobed, reflexed, ca. 0.3 mmlong. Drupe subglobose, 1-locular, 1-seeded; red at maturity.
Etymology: Đại diệp thanh hƯƠng mộc(Vietnamese, referring to its broad leaflets and aromatic properties); 大 叶ậē† (Chinese, large-leaved pistacia). Phenology:—Flowering in October to February of the next year; fruiting in April to June.
Distribution, habitat and provisional conservation status:— Pistacia cucphuongensisis distributed in North Vietnam( Cao Bang, Hai Phong, Ninh Binh, Thanh Hoa, Quang Binh) and South China( Guangxi). It grows on limestone hills at elevations of 200– 900 m. Based on IUCN Red List Categories and Criteria (IUCN Standards and Petitions Committee 2024), we propose a provisional assessment of ‘Least Concern’ (LC), as it is a common species and has a wide distribution range. Potential usage:—In China, especially in Yunnan Province, leaves of P. weinmannifoliaare traditionally used for incense production, and its resin is used for medicine (Ming & Barfod 2008). Our field observations indicate that the crushed branchlets and leaves of P. cucphuongensisemit a similarly aromatic resin. Although no documented uses exist for P. cucphuongensis, its close phylogenetic relationship with P. weinmannifolia(Xie et al. 2014)warrants further investigation into shared phytochemical properties and potential uses.
