Song sp. nov.</p><p>Figs 4, 5</p><p>Diagnosis.</p><p>The new species similar to P. praecox, P. cyrtonema, and P. odoratum . It differs from P. praecox in having a terete rhizome, white corolla, 2–4 seeds; differs from P. cyrtonema in having a terete rhizome, white corolla, filament cylindrical and extending inwardly, smooth, and glabrous, 2–4 seeds; differs from P. odoratum in having a yellow rhizome, upper part angled stem, 2–4 seeds.</p><p>Type.</p><p>China • Anhui Province: Luan City, Huoshan County, Mt. Nanyueshan, 12 Mar 2022, Song SXW 220312 (holotype: ACM; isotype: PE) .</p><p>Description.</p><p>Rhizome terete, 1.0–2.0 cm thick. Stem arching, 30–70 cm, glabrous, and terete. Leaves 10–18, alternate; petiole short or nearly sessile; leaf blade elliptic, 5.0–7.0 × 3.5–5.0 cm, apex usually short mucro. Inflorescences raceme, 1–2 (3) flowered; peduncle 1.0– 1.5 cm; bracteoles borne on the middle part of pedicel, subulate, 0.5–1.5 mm, or absent. Flowers pendulous, pedicel 0.5–1.0 cm long. Perianth white, campanulate-cylindrical, 1.5–2.0 cm long; lobes 2–3 mm long, excurved. Filaments inserted near the distal 1 / 2 of the perianth tube, cylindrical and extending inwardly, 2.5–5.0 mm long, smooth, apex without saccate-convex. Anthers 3.0– 3.5 mm long. Ovary 3–5 mm in diam. Berries blue-black, 0.8–1.0 cm in diam, 2–4 seeded.</p><p>Phenology.</p><p>Growth initiated in February, flowering in March – April, and fruiting in April – October.</p><p>Distribution and habitat.</p><p>Primarily in moist, deciduous, bamboo forests and broad-leaved forests, 150–1000 meters; documented on the slopes of Dabieshan Mountains, in Anhui and Henan Provinces.</p><p>Etymology.</p><p>Derived from the name of the Dabieshan Mountains, where Polygonatum dabieshanensis was discovered.</p><p>Chinese name.</p><p>大别山黄精 (da bie shan huang jing)</p><p>Morphological comparison.</p><p>Morphological comparisons between the new taxon and other Polygonatum species revealed that it is most similar to P. praecox, P. cyrtonema, and P. odoratum . However, it can be distinguished from P. praecox, P. cyrtonema, and P. odoratum by distinct features of the rhizome, leaves, stem, inflorescence, filament, corolla, and flowering phenology (Table 3).</p></div>	https://treatment.plazi.org/id/D484BDD6BD825839886141C3271B284B	Public Domain	No known copyright restrictions apply.
