Young twigs brownish or grayish black, puberulent to glabrous. Petioles 2–4 mm long, 0.9–1.5 mm in diameter; leaf blades oblong-elliptic to oblong-ovate, 4.2–14.3 × 1.5–4.0 cm, base cuneate to obtuse, apex acute to attenuate, leathery, adaxially sparsely puberulent to glabrous, abaxially glabrous; midrib slightly impressed and sparsely puberulent to glabrous above, raised and sparsely puberulent below; secondary veins 10–20 on each side of the leaf, anastomosing within margin, prominent above, distinctly raised below; tertiary veins reticulate, prominent abaxially and adaxially. Inflorescence leaf-opposed or supra-axillary; 1–4 flowers per inflorescence. Peduncles absent or up to 2.5 mm long. Pedicels (2.0 –) 5.5–8 mm long, 0.8–1.0 mm in diameter, puberulous, with one pubescent median or basal bract. Flowers yellow, 1.0– 1.4 cm in diameter when fresh. Sepals ovate, 0.7–1.0 (– 1.5) × 1.4–1.7 (– 2.0) mm, pubescent abaxially, sparsely puberulent to glabrous adaxially; outer petals ovate, 9–12 × 6–8 mm when fresh, 7–9 × 5–6 mm when dry, base cuneate to attenuate, apex acute, pubescent abaxially, puberulent adaxially; inner petals narrower, 11–14 × 5–7 mm when fresh, 10–12 × 4.5–5.5 mm when dry, base cuneate, apex acute, puberulous to puberulent abaxially, sparsely puberulent to glabrous adaxially. Stamens “ miliusoid ” with very short connective prolongation not extending over pollen sacs, 20–30 per flower, ca. 1 mm long, in 3 whorls. Carpels 2–6 per flower, ca. 1.5–2 mm long, puberulous to puberulent; ovules ca. 8 per carpel, biseriate. Fruiting pedicels 6.5–7.8 mm long, 1.7–2.6 mm in diameter; monocarps 1–4 per fruit, subglobose to oblate, 2.1–3.4 cm long, 2.0– 2.7 cm in diameter, yellow when mature, shortly pubescent, smooth, apex rounded; stipes 3.5–4.6 mm long, 2–2.6 mm in diameter. Seeds up to 8 per monocarp, flattened ellipsoid, 1.6–2.1 cm long, 0.9–1.3 cm wide, 0.5–0.8 cm thick; endosperm rumination lamelliform.</p><p>Phenology.</p><p>Flowering from January to May, and fruiting from July to September.</p><p>Distribution and habitat.</p><p>According to our field investigation and herbarium records, Alphonsea yunnanensis is distributed in several localities of 16 counties and cities across the Yunnan Province (Fig. 4; Chen et al. 2024). It has small trees growing in subtropical limestone evergreen-deciduous broad-leaved mixed forests at 1000–1800 m elevations. As field surveys progress, additional populations are expected to be discovered in its distribution ranges.</p><p>Conservation status.</p><p>This species was previously assessed as critically endangered (CR) (IUCN 2004; Li and Gilbert 2011) and listed as a Plant Species with Extremely Small Populations (PSESP) in Yunnan (Ren et al. 2016; Sun 2021). According to the current distribution of Alphonsea yunnanensis (Fig. 4), the extent of occurrence (EOO) for it is 95,142 km 2 and the area of occupancy (AOO) is 76 km 2, as calculated by Shiny-GeoCAT (Moat et al. 2023). Based on our initial field investigation, the average number of flowering and fruiting individuals in the wild populations is less than 5. Most distribution points are located on limestone hills or at the edges of river valleys, and they are vulnerable to disturbances. Based on the IUCN Red List Categories and Criteria (IUCN 2024), notably on the number of locations, mature individuals and the AOO, this species qualifies for classification as Endangered (EN, B 2 ab (iii, v) D).</p><p>Additional specimens of Alphonsea yunnanensis examined.</p><p>China.
