Many specimens previously identified as belonging to this species in the herbarium are actually misidentified and belong to other species. Additionally, the distribution of this species in Yunnan requires further confirmation.</p></div>	https://treatment.plazi.org/id/ED5D87D9FFBAFFC0C0F827D432AEF8EA	Public Domain	No known copyright restrictions apply.

Type herbarium specimen prepared in 22 May 2023 from plants cultivated in Garden of IBSC, C. X. Peng 0373 (holotype: IBSC9301377!; isotype: IBSC9301376!), originated from Guangxi, Chongzuo, Tiandeng, Fuxin, Wanxiu, the vicinity of Buxiu, alt. 224 m.</p><p>Diagnosis: — Ophiopogon tiandengensis resembles O. tonkinensis, but can be readily distinguished from the latter by its blade obovate, smaller in size, pedicel articulated in the middle, inflorescence ca. 25 flowered, flower campanulate and lobes not reflexed but somewhat divergent distally; and flowering in May–July (vs. in October to December).</p><p>Description: —Herbs, perennial, evergreen. Rhizome very short, ca. 1.5 cm long, 0.6 cm in diam. Roots ca.</p><p>4 mm in diam., pubescent. Leaves basal or tufted glabrous; petiole 3–5 cm long, ca. 2.5 mm in diam., pale green; blade obovate, 6.5–9.1 cm long, 2.2–3.2 cm broad, entire, leathery, adaxially green, abaxially pale green with 23–28 whitish green longitudinal streaks, basally cuneate and asymmetric, acute at apex. Cataphyll membranous, quickly withering, brown. Scape 5–6 cm long, green, glabrous. Inflorescence terminal, reduced panicle 5.5–8 cm long, erect, green, glabrous, ca. 25 flowered, in clusters of 2 or 3; outer bract ca. 4 mm long, boat-shaped, centrally pale green, marginally purple, inner bract 0.8–1.5 mm long. Flowers hermaphroditic, campanulate, in clusters colate, in clusters of 1 or 2, facing downward. Pedicel articulated, 4.5–8.0 mm long; portion below articulation ca. 2–3 mm long, dark purple; portion above articulation 2.5–5.0 mm long. Perianth ca. 5.5 mm long, ca. 6.5 mm in diam., purplish; lobes 6, oblong to elliptic, apex reflexed, 4.5–5 mm long, 2–2.5 mm broad. Stamens 6, ca. 2 mm long, introrse; filaments free, ca. 1mm long, ca. 0.5 mm broad, pale green; anthers ovoid, ca. 0.7 mm long, cream. Ovary half inferior, 3 locules at distal part and septum disappears thus locules at base. Style 4.5 mm long, slender, white, exceeding perianth by 1 mm at maturity. Seeds spherical, 1.3 cm in diam.</p><p>Phenology: —Flowering from May to July.</p><p>Distribution and habitat: — Ophiopogon tiandengensis is only distributed in the damp valleys on the shady slopes of limestone hills in the southwestern part of Guangxi. In addition to the type locality in Tiandeng County, the species is also distributed in places such as Longzhou County, Jingxi County, Daxin County (see Additional specimens examined).</p><p>Etymology:—The specific epithet tiandengensis is derived from Tiandeng County, where it was discovered. The Chinese name for Ophiopogon tiandengensis is provided here as “ 天Şȁẖặ ” (Tiān děng yán jiē cǎo), “ ȁ ẖặ ”is the common Chinese name for the genus Ophiopogon, while “ 天Ş ” directly translated the specific epithet tiandengensis .</p><p>Conservation status:—Based on field surveys, the species is widely distributed in southwestern Guangxi, but each population is relatively small. Although some populations are located within protected areas, this plant is sold online as a small bonsai and has high ornamental value, leading to extensive collection that has caused a rapid decline in both population and individual numbers. And its population is estimated to decrease by 50% in the next ten years. According to the IUCN's A2c (IUCN 2024) standard, it is rated as Endangered (EN).</p><p>Note: — Ophiopogon tiandengensis is similar to O. tonkinensis, but its blades obovate to suboblong (vs. oblanceolate-oblong), 6.5–9.1× 2.2–3.2 cm (vs. 8.3–23.5 × 2.0– 6.3 cm), petiole 3–5 cm long (vs. 8–32 cm long), pedicel portion above articulation 2.5–5 mm long (vs. 11–19 mm long) and articulated in the middle (vs. articulated in the lower), inflorescence ca. 25 flowered (vs. ca. 51 flowered), flower campanulate and lobes top not reflexed but somewhat divergent distally (vs. urceolate and lobes top reflexed) and flowering from May–July (vs. in November).</p><p>In addition, Ophiopogon tiandengensis is somewhat similar to O. sinensis Y. Wan &amp; C.C. Huang (1987: 398) (Figs. 10) with their perianth lobes white to light purple and being somewhat divergent distally. O. sinensis was described on the basis of a single specimen, C.C. Huang 12252 (GXMG0039018!), type herbarium specimen prepared from cultivated plant in GXMG, Nanning, Guangxi, China and origin unknown. Based on Chen &amp; Tamura (2000), Yang &amp; Li (1990) and Yang (1997), this species also distributed in Southeastern Yunnan. In the protologue, the author stated that O. sinensis similar to O. bockianus Diels (1900: 254) but differing by the following characters: leaves oblanceolate-oblong, 3.2–4 cm wide; scape shorter (ca. 14 cm long); pedicels longer (12–15 mm long); anthers lanceolate (ca. 4.5 mm long), initially coherent but becoming discrete. Thus, there are significant differences between O. tiandengensis and O. sinensis . The leaves of O. sinensis are oblanceolate-oblong to suboblong and petiolate indistinctly. Additionally, the anthers are lanceolate and ca. 4.5 mm long. The most critical difference is that the anthers of O. tiandengensis are initially connate, later free. The differences in these three species are mentioned in Table 1.</p><p>Additional specimens examined:— Ophiopogon tiandengensis . CHINA. Guangxi: Longzhou County, 20 July 2009, R. H. Jiang, W. H.
