H. Wu, J. F. Zhang & J. Q. Guo 2025	<div><p>Strobilanthes danxiaensis B. H. Wu, J. F. Zhang &amp; J. Q. Guo sp. nov.</p><p>Fig. 2</p><p>Type.</p><p>China • Guangdong Province: Shaoguan City, Renhua County, Danxia Mountain area, 250 m a. s. l., in moist valleys, 4 December 2024, Jian-Qiang Guo and Bao-Huan Wu Lg 2024179 (holotype: SYS!; isotype: SYS!; IBSC!) .</p><p>Diagnosis.</p><p>Morphologically, Strobilanthes danxiaensis is most similar to S. tetrasperma, but differs in its longer corolla (2.8–4 cm vs. 1.5–2 cm), with larger, emarginate oblong – obovate corolla lobes (ca. 1 × 1 cm vs. oblong lobes ca. 4 × 5 mm with obtuse apices), and a much longer style (3 cm vs. 1.5 cm).</p><p>Description.</p><p>Perennial herb, up to 80 cm tall. Stems slightly prostrate at base, becoming erect or ascending upwards, quadrangular, white tomentose, gradually glabrescent below. Leaves opposite; petiole 0.3–1.1 cm long, white tomentose; blade ovate to elliptic, 6.5–10 × 3.8–5.5 cm, adaxially green and sparsely puberulous with short white hairs, cystoliths absent or sometimes sparsely present, abaxially pale green, tomentose along veins and conspicuously glandular-cystic; lateral veins 4–5 (– 6) pairs, prominently raised on both surfaces; base attenuate, apex acute; margin crenate-dentate with obtuse teeth. Inflorescences short terminal spikes, 1–4 cm long, often elongating at maturity, bearing 2–4 flowers; rachis tomentose. Bracts leaf-like, obovate to obovate-spatulate, 1–2 × 0.5–1 cm, puberulous on both surfaces, margin shallowly serrate, apex obtuse, base attenuate. Bracteoles linear to oblanceolate, 0.8–0.9 × 0.1–0.2 cm, midrib conspicuous, entire, densely white-hirsute on both surfaces. Calyx 5 - lobed almost to base; lobes linear, 0.8–1.1 cm long, midrib prominent, densely pubescent on both surfaces, apex obtuse. Corolla pale purple to whitish, funnel-shaped, 2.8–4 cm long, slightly inflated and curved, externally puberulous, internally pubescent in throat and downward; tube basally cylindrical, ca. 2 mm wide, 1.1–1.3 cm long, gradually widened towards mouth; orifice 1.6–3 cm wide, 2–2.8 cm high; lobes oblong to obovate, subequal, ca. 1 × 1 cm, emarginate at apex. Stamens 4, included; filaments sparsely pubescent; shorter pair ca. 2 mm long, longer pair ca. 6 mm long. Anthers narrowly ellipsoid, ca. 3 mm long. Ovary cylindrical, ca. 3 mm long, upper 2 / 3 densely pubescent; style ca. 3 cm long, sparsely pubescent. Capsule narrowly ellipsoidal, ca. 1 cm long, ca. 2.5 mm in diam., upper 2 / 3 pubescent, 4 - seeded.</p><p>Phenology.</p><p>Flowering from November to January; fruiting in March.</p><p>Etymology.</p><p>The specific epithet “ danxiaensis ” refers to the type locality, Danxia Mountain in Guangdong Province, China, to commemorate this unique landform and the rich plant diversity it harbors.</p><p>Distribution and habitat.</p><p>Strobilanthes danxiaensis is known only from Danxia Mountain, Guangdong Province, China. Only three populations have been discovered, with a total of fewer than 100 individuals. They grow in moist valleys at elevations of 350– 400 m. Associated species include Maesa perlarius (Lour.) Merr., Alocasia odora (Roxb.) K. Koch, S. dimorphotricha Hance, Oplismenus compositus (L.) P. Beauv., Tectaria devexa Copel., and Lobelia nummularia Lam.</p><p>Conservation status.</p><p>Strobilanthes danxiaensis is currently known from only three small populations in moist valleys on Danxia Mountain. However, the species occurs in a rugged and heterogeneous landscape where botanical surveys remain incomplete, and additional suitable habitats in the region have not yet been systematically explored. There is insufficient evidence to formerly assess the species using IUCN guidelines and we consider this species to be Data Deficient (DD).</p></div>	https://treatment.plazi.org/id/2D01A4348C3850969ECBC9E51098FFBB	Public Domain	No known copyright restrictions apply.
