Branches of the current year purplish or brown-purple, puberulent; second-year branches green, glabrescent; third-year and older branches greyish to brownish-grey, glabrescent. Petioles 6–10 mm long, green to purplish, puberulent, but glabrescent with age. Leaf blades lanceolate, elliptic, ovate-elliptic or obovate-elliptic, 3.7–8.5 cm long, 1.8–3.4 cm wide, chartaceous, both surfaces glabrous, sometimes sparsely puberulent along the mid-vein abaxially, secondary veins 7–11 pairs, base cuneate to obtuse, margin entire, apex acuminate to long acuminate. Stipules tiny, triangular to broadly triangular, dark brown, glabrous, base rounded, margin entire, apex acute, caducous. Male inflorescences and flowers unknown. Female inflorescences axillary, occurring on current-year and / or second-year branches, cymose, corymbiform, ca. 1.5–2 cm in diameter, with (1 –) 3–18 flowers per inflorescence (rarely a branch with several cymes resembling a thyrse due to development of bracts instead of foliage leaves); peduncles 5–14 mm long, puberulent; bracts tiny, triangular to broadly triangular, brown to dark brown; rachises of thyrse-like branches 2–4 cm long, puberulent. Female flowers: pedicel 4–9 mm long, puberulent; calyx ca. 2.5 mm in diameter, yellowish-green and scarious along margin, puberulent outside and glabrous inside, 6 - or 7 - lobed, lobes broadly deltoid and overlapping each other; corolla 4.5–6 mm in diameter when fully opened, tube ca. 1 mm long, lobes (8 –) 9–10 (– 11), elliptic, 1.8–2.1 mm long, 0.8–1 mm wide, pink to pink-violet, glabrous, rarely with sparse hairs along margin, apex rounded; staminodes 9–10 (– 11), usually in the same number as the petals, ca. 2 / 5 as long as the petals, glabrous, filaments pink, sterile anthers deltoid, pinkish-white; ovary superior, ca. 1.5 mm in height, subglobose or elliptic in top view due to the carpels arranged along a line, green, glabrous, with 9–10 locules, each locule 1 - ovuled; stigma elliptic-discoid, green, 9–10 - lobed. Fruits when young green, glabrous, with persistent puberulent calyx; ripe fruits unknown.</p><p>Etymology.</p><p>The species is named for its female flowers that mostly have 10 petals, which makes it distinct within the holly genus, because the flowers of Ilex are predominantly 4–7 - merous.</p><p>Phenology.</p><p>Ilex decapetala starts to flower in April or May; fruiting season is unknown.</p><p>Distribution.</p><p>Ilex decapetala is currently known from three neighbouring provinces of central Vietnam, i. e. Kon Tum, Quang Nam and Thua Thien Hue (Fig. 5). Two of the localities are within several km of the border with Laos, which means that the presence of the species in Laos is highly possible.</p><p>Preliminary conservation assessment.</p><p>DD (Data Deficient). Three populations were recorded, with the two most distant ones located 185 km apart from each other. Further field observations on the species and an assessment of the quality of its habitats are needed.</p><p>Paratypes.</p><p>Vietnam • Thua Thien Hue: A Luoi 4 Commune, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=107.41653&amp;materialsCitation.latitude=16.145185" title="Search Plazi for locations around (long 107.41653/lat 16.145185)">A Roang 2 Village</a>, remnants of primary evergreen broad-leaved forest on sandstone mountain, around point 16.145186°N, 107.416529°E, elev. 600–700 m a. s. l., 27 April 2026, Ninh Khac Ban, Bui Van Thanh, Khang Sinh Nguyen et al.
