Leaves opposite; petiole ferruginous to rufous, terete, 2.5–6 cm long, puberulent when young, then glabrescent; blade oblong to ovate-oblong, or broadly ovate, 9.5–19 × 4.5–10 cm, stiffly papery, base obtuse, broadly cuneate, margin inconspicuously denticulate, apex acuminate with a tip up to ca. 1 cm, adaxially light green, often with prominent whitish spots arranged in two lines on both sides of the midvein when young, abaxially green, ferruginous to rufous along midvein; secondary veins 2 on each side of midvein; tertiary veins numerous, parallel. Inflorescences of an axillary umbel, 3–5-flowered; peduncle ca. 3 mm, puberulent; bracts subulate, ca. 3 mm long, margin serrate, caducous. Pedicel 0.8–1 cm long, ± puberulent. Hypanthium campanulate-cupuliform, ca. 1 cm long, obtusely quadrangular, ± puberulent, with irregular horns up to ca. 3 mm long. Calyx lobes triangular, 3–4 × 1.5–2 mm, adaxially puberulent and strongly concave to nearly folded, abaxially convex and ridged, margin irregularly dentate, apex obtuse. Petals pink, broadly ovate, oblique, 1.4–1.6 × 0.9–1.1 cm, glabrous, apex acuminate. Stamens 8, antisepalous 4 longer, antipetalous 4 shorter, arranged in 2 whorls. Antisepalous stamens 2.0– 2.2 cm long; filaments pink, 1.0– 1.1 cm long, glabrous; anthers pink, lanceolate, strongly curved, 1.0– 1.1 cm long; connective slightly decurrent, basally with 2 ventral cream tubercles ca. 1.0– 1.2 mm long and a dorsal short cream spur ca. 0.7 mm long. Antipetalous stamens 1.2–1.4 cm long; filaments pink, 6–7 mm long, glabrous; anthers pink, lanceolate, strongly curved, 6–7 mm long; connective slightly decurrent, basally with 2 ventral yellow tubercles 1.0– 1.2 mm long and a dorsal short yellow spur ca. 0.7 mm long. Ovary inferior, urceolate to ovoid, quadrangular, ca. 8 × 4 mm, crown 4-lobed, apex irregularly denticulate with glandular trichomes; style white to pinkish, slightly curved, 1.6–1.7 cm long, glabrous, stigma obtuse. Capsule ovoid, obtusely quadrangular, ca. 8 × 4 mm. Seeds more than 100, ellipsoid, ca. 0.5 mm long.</p> <p>Etymology:— The species is named after the country Vietnam where it was discovered.</p> <p>Phenology:— Flowering from July to August; fruiting from August to March of next year.</p> <p>Distribution and habitat:— The species is currently only known from a few localities in Lao Cai and Bac Kan, northern Vietnam. It grows at shady places under primary or secondary evergreen broad-leaved submontane forests on steep granite and quartzite slopes along streamside at elevations of 680–1350 m.</p> <p>Conservation status:— The species was collected from several localities in Lao Cai and Bac Kan, northern Vietnam. All localities are protected areas of the Hoang Lien-Van Ban Nature Reserve and Kim Hy Nature Reserve. The new species grows at undisturbed sites and no anthropogenic threat has been detected. There are no data on population assessment in the field now. According to our prediction, the new species could be present in other locations with similar habitat conditions of the type locality. Therefore, it may be accessed to be ‘Data Deficient’ (DD) according to the IUCN Red List Categories and Criteria (IUCN 2022).</p> <p>Additional specimens examined (paratypes):— VIETNAM.

Sporoxeia vietnamensis can be easily distinguished from other species of Sporoxeia by the stiffly papery leaf blades, larger and densely horned hypanthia, and larger calyx lobes and petals. Its horned hypanthia and nearly folded calyx lobes are uncommon in the Asian Melastomataceae. The horned hypanthia also occur to some species of Pternandra Jack (1822: 60) of the tribe Kibessieae, e.g., P. echinata Jack (1822: 3). An identification key to the species of Sporoxeia is provided below.</p> </div>	http://treatment.plazi.org/id/03908781FF8BFFF8EBE0FD243C7BE1A1	Public Domain	No known copyright restrictions apply.
