Stems mostly several, erect, glabrous, angulate, 2–6 mm in diameter. Leaves 3–9 cm long; stipules triangular or ovoid, green to red purple, ca. 10–15 × 4–8 mm, glabrous; petiole 5–10 mm long, glabrous; leaflets 11–17, obovate, narrowly oblong, 10–22 × 4–8 mm, glabrous on both surfaces, base asymmetric, apex obtuse and mucronulate. Racemes 8 - to many-flowered, elongate after anthesis; peduncle 5–15 cm long, red purple, sulcate, glabrous; bracts oblong or ovoid, green to red purple, 8–15 mm long, glabrous; bracteoles adnate to the calyx oblong or obovate, glabrous, green to red purple, ca. 5–10 × 2–4 mm; pedicels glabrous ca. 2.5 mm. Calyx campanulate, ca. 7 mm long, glabrous, green to red purple and turn red purple at fruiting; unequal lobes subulate, ca. 3 mm long, glabrous. Petals green-yellow to yellow, standard ca. 15 × 8 mm, obovate, without distinct claw, apex emarginate; wings ca. 14 mm long, claw ca. 8 mm long, auricle ca. 1 mm long, blade oblong, ca. 6 × 2.5 mm, apex rounded; keel ca. 14 mm long, claw ca. 8 mm long. Stamen diadelphous filaments glabrous, anthers round. Ovary with a stipe ca. 1.5 mm, glabrous; style and stigma glabrous. Legumes inflated, obliquely ellipsoid, with a stipe 10–14 mm at base, 20–30 × 6–10 mm, with a beak 2 mm; valves membranous, glabrous, becoming red-purple with age and red-purple at maturity.</p><p>Phenology.</p><p>Flowering and fruiting from Jun. to Sept.</p><p>Distribution and habitat.</p><p>Astragalus baimaensis is endemic to the alpine zone of Baima Mountain, Deqin County, southwestern Yunnan, southwestern China, growing among alpine shrubs or in alpine meadows at elevations of 4,200 –4,400 m (Figs 1, 2).</p><p>Taxonomic notes.</p><p>The newly described Astragalus baimaensis exhibits close morphological similarity to the sympatric A. tongolensis but can be immediately distinguished by its leathery or papery leaflets that are glabrous on both surfaces, accompanied by a fully glabrous calyx, ovary, and legume. Another completely glabrous congener, A. luculentus, can be easily distinguished from the new species by a combination of independent characters: A. luculentus has larger leaves that are 25–30 cm long with 8–11 cm long petioles, a standard ca. 25 mm long, and subsessile, straight, incompletely bilocular legumes with thick, leathery valves.</p><p>Conservation status.</p><p>Astragalus baimaensis is currently known exclusively from Baima Mountain, with an estimated area of occupancy of less than 500 km 2, which meets the requirements for the Endangered (EN) category under IUCN Red List criterion B 2. This taxon occurs at fewer than five threat-defined locations (criterion B 2 a) and faces a continuing decline in habitat quality driven by anthropogenic disturbances and intensified climate warming — two stressors with disproportionately severe effects on high-altitude alpine species (criterion B 2 b (iii)). Classification of this new species as Endangered (EN) under the IUCN Red List Categories and Criteria (2012) is therefore recommended.</p><p>Etymology.</p><p>The specific epithet refers to the type locality, Baima Mountain, Yunnan Province, China.</p></div>	https://treatment.plazi.org/id/E333FF4280CB5C91B06C00490C2BFAB0	Public Domain	No known copyright restrictions apply.
