Y. Zhang, J. L. Gu &amp; Y. Hu, ZSY 20260201 (holotype: ANUB 100131!; isotypes: ANUB 100132!) .</p><p>Diagnosis.</p><p>Primula pingwuensis is morphologically similar to P. sinensis in having palmately lobed leaves and multi-whorled scapes but differs by its multi-branched stems, densely pubescent indumentum, thickly chartaceous leaves (vs. submembranous in P. sinensis), narrower blades (3–6 cm wide), 2–3 flower whorls, and indistinct translucent nectar guides. Primula pingwuensis shares a close evolutionary affinity with P. rongrong and P. fujiangensis . The three taxa exhibit high morphological resemblance and overlapping geographical ranges. P. pingwuensis bears palmately lobed foliage, with all vegetative and floral parts shortly and densely pubescent, plus faint inconspicuous nectar guides. In contrast, both allied species produce pinnately divided leaves: P. rongrong is fully villous and lacks nectar channels, whereas P. fujiangensis is densely pubescent and bears conspicuous purple nectar ducts. This set of consistent morphological characters readily distinguishes P. pingwuensis from the two allied taxa.</p><p>Description.</p><p>Perennial herb, 8–20 cm tall. Rhizomes brown, 3–10 cm long, branched near the apex, comparatively stout. Leaves 7–15 in an open rosette; petioles 5–15 cm long, green or yellowish-brown, broadly flattened at the base, densely white-pubescent; leaf blades elliptic-ovate to suborbicular, 4–8 × 3–6 cm, chartaceous-fleshy, shortly and densely white-pubescent; adaxially green to yellow-green, abaxially pale green to purplish-red; palmately lobed to 1 / 3–1 / 2 of its width, lobes usually 7, rectangular, with 3–5 fine serrations along the margin; base cordate, lateral veins 3–4 on each side. Scape solitary, arising from each leaf rosette, 10–20 cm tall, densely white-pubescent; umbels 2–3 whorled, each whorl with 3–7 flowers; bracts lanceolate to long-triangular, 8–15 mm × 2–8 mm, apex acute, densely white-pubescent; pedicels 2.0– 3.5 cm long, densely white-pubescent. Glandular hairs absent on pedicels and calyx. Flowers heterostylous; calyx bell-shaped, 5–7 mm long, 5–7 mm in diam., inflated at base in fruit, lobed to approximately 1 / 2 of its length, lobes triangular, margin entire, densely white-pubescent; corolla pink, puberulous on both surfaces; throat white, with indistinct pale yellow or translucent nectar guides; limb 2.0– 2.6 cm in diam., lobes 5, obovate, 2 - lobed at apex, parted to 1 / 6–1 / 4 of the lobe length. Pin flowers with corolla tube ca. 10 mm long, stamens attached below the middle, style reaching or slightly protruding from the corolla throat, 10–12 mm long; thrum flowers with corolla tube ca. 10 mm long, stamens inserted near the corolla throat, style 5–7 mm long. Stigma globular; ovary globular, glabrous, ca. 2 mm in diam., ovules numerous. Capsule subglobose, 6–8 mm in diam., dehiscing at the apex when mature, usually with seven triangular lobes. Seeds numerous, black, ellipsoid, approximately 1 mm long.</p><p>Phenology.</p><p>Flowering from January to March, fruiting from May to June.</p><p>Distribution and habitat.</p><p>It grows on shaded conglomerate cliff faces in valleys at altitudes of 600–800 m. At present, it is known only from Pingwu County, where two populations occur approximately 30 km apart.</p><p>Chinese name.</p><p>Píng Wŭ Bào Chūn (平武报春).</p><p>Etymology.</p><p>The specific epithet is derived from Pingwu County, Mianyang City, Sichuan Province, the type locality of the new species, which is also an important habitat of the giant panda.</p><p>Provisional conservation status.</p><p>Primula pingwuensis is currently known from only two localities, with an area of occupancy (AOO) of less than 10 km 2. Intensive human activities take place around both distribution sites, although no obvious negative impacts on wild populations have yet been documented. However, long-term population and habitat monitoring data are absent, so it cannot be confirmed whether its populations or habitats are undergoing continuous decline. Given the insufficient ecological and demographic data available for formal threatened-category evaluation, this species is assessed as Data Deficient (DD) under the IUCN Red List Categories and Criteria (Version 16.0, IUCN 2024).</p></div>	https://treatment.plazi.org/id/02B5D451E4995D10A0DFA686242E6A83	Public Domain	No known copyright restrictions apply.
