Y. Zhang, ZSY 202208001 (holotype: ANUB 100125!; isotypes: ANUB 100126!, ANUB 100127!, CSH 0221073!, CSH 0221074!, CSH 0221075!) .</p><p>Diagnosis.</p><p>The new nothospecies resembles its parental taxa ( Lycoris longituba and L. sprengeri), but is distinguished by its perigone tube typically measuring 1.5–3.5 cm in length and flowers that are usually pink to pale pink, rarely white or pale yellow, with tepal apices sometimes pale blue. In contrast, L. sprengeri exhibits a perigone tube less than 1.3 cm long, deep pink flowers, and tepal apices that are usually distinctly blue, while L. longituba possesses a notably longer perigone tube (3–6.5 cm), flowers that are white, lemon-yellow, or cream-yellow (very rarely pale pink), and tepal apices that never display a blue coloration.</p><p>Description.</p><p>Perennial herb. Bulb ovoid, 3.5–5 cm in diameter, covered with brown cataphylls bearing fine longitudinal striations. Leaves linear, usually 6–9 (– 13), apex obtuse, emerging in winter to early spring, 30–45 cm long, 1.5–2.5 cm wide, green to dark green, midrib slightly sunken, surface thinly white-pruinose. Scape 40–70 cm high, green; spathe bracts 2, lanceolate, ca. 4 cm long, 8–15 mm wide. Umbels with 5–7 flowers; pedicels 1.5–3 cm long, ca. 3 mm in diameter; flowers typically pink to pale pink, occasionally white or pale yellow, sometimes with pale blue tepal apices. Tepals oblanceolate, 5.5–9 cm long, 1–2 cm wide, apex slightly recurved and occasionally faintly crisped; perigone tube pale green, ca. 15–35 mm long. Filaments 4.5–8 cm long, white to pale pink, slightly exceeding tepals; anthers yellow, 3–5 mm long; style 8–13 cm long, pale pink with purple apex. Ovary spherical, green, 5 mm in diameter. Capsules trigonous, failing to produce seeds at maturity.</p><p>Phenology.</p><p>Flowering from late July to late August; leaves growing from late February to early March.</p><p>Distribution and habitat.</p><p>Currently confirmed only from the type locality (Chuzhou City, eastern Anhui Province), but potentially occurring in adjacent areas of Nanjing City and Zhenjiang City, Jiangsu Province. It grows in deciduous broad-leaved forests on limestone hills, in mixed populations where Lycoris sprengeri (eastern Hubei, central-eastern Anhui, central Jiangsu) and L. longituba (central-eastern Anhui, central Jiangsu) co-occur.</p><p>Etymology.</p><p>The specific epithet commemorates the renowned literary figure of China’s Northern Song Dynasty, Xiu Ouyang (欧阳修), whose iconic work “ The Old Drunkard’s Arbor ” (《 醉翁亭记 》) has made the discovery site of this nothospecies — Langya Mountain — nationally famous. The Chinese name is designated as 亭城石蒜 (Tíng Chéng Shí Suàn). Tíng Chéng (亭城) is the alias of Chuzhou City, where this new nothospecies was discovered. The historical culture of Chuzhou is closely intertwined with Langya Mountain and the Old Drunkard’s Pavilion (醉翁亭). Shí Suàn (石蒜), the Chinese name of the genus Lycoris, literally means “ a garlic-like plant growing among rocks. ”</p><p>Reproduction.</p><p>This nothospecies is functionally seed-sterile and reproduces exclusively through natural vegetative propagation via bulb division. A single bulb typically forms a cluster of 2–3 daughter bulbs after two growing seasons.</p></div>	https://treatment.plazi.org/id/E9CDCF42D36F5061878FAFE0E023CEB6	Public Domain	No known copyright restrictions apply.
