X. Wu, Z. H. Li & Qiang Wang 2026	<div><p>Pogostemon puerensis X. X. Wu, Z. H. Li &amp; Qiang Wang sp. nov.</p><p>Figs 3, 4</p><p>Type.</p><p>China • Yunnan province, Pu’er City, Ning’er Hani and Yi Autonomous County, Ning’er town, along County Road X 013, ca. 1.4 km N of Xiaoheijiang Forest Park, at an elevation of approximately 933 m, 9 May 2025, X. X. Wu et al. WXX 25015 (holotype, PE; isotype, PE) .</p><p>Diagnosis.</p><p>Pogostemon puerensis is morphologically similar to P. hainanensis and P. parviflorus but can be readily distinguished from both by its plant height 0.3–1.5 m (vs. 0.8–2 m in P. hainanensis and 0.3–0.6 m in P. parviflorus); lateral veins five pairs on each side of the midvein (vs. 3–4 pairs in P. hainanensis and 4–5 pairs in P. parviflorus); bracteoles 1–2 mm long (vs. 2.5–5 mm in P. hainanensis and 4–6 mm in P. parviflorus); the inner surface of the calyx tube densely hairy in the upper two-thirds (vs. occasionally hairy only near the upper part of the tube in P. hainanensis and sparsely strigillose only in the upper part of the tube in P. parviflorus); corolla with purplish-red blotches on the middle lobe of the 3 - lobed upper lip (vs. corolla entirely white in P. hainanensis and white, pink, or purplish in P. parviflorus); corolla tube with a conspicuous ring of hairs (vs. without a conspicuous ring of hairs); and stigma lobes 2.8–3.1 mm long (vs. 1.2–1.7 mm in P. hainanensis and ca. 0.7 mm in P. parviflorus).</p><p>The new species can be further distinguished from its sister species in the ITS phylogeny, P. cablin, by its shorter bracteoles (1–2 mm vs. 4–8 mm), strongly exserted corolla (1.0–1.5 × calyx length vs. slightly exserted), and differences in phenology (flowering from December to February vs. March to May).</p><p>Description.</p><p>Perennial herbs; base woody; plants ca. 0.3–1.5 m tall. Stems erect, 3–5 mm in diam., quadrangular, solid; nodes slightly swollen; unbranched or sparsely branched; stems densely pubescent with soft hairs. Leaves opposite, papery to membranous; blade ovate to ovate-elliptic, 7.5–14.1 (– 16.0) × 5.4–9.31 (– 10.2) cm; apex attenuate; base cuneate to broadly cuneate; margin coarsely serrate except entire near base, teeth obtuse-rounded or acute; midrib prominent abaxially; lateral veins 5 (rarely 3) pairs, raised on abaxial surface; both surfaces densely covered with ferrugineous strigose hairs. Petiole (– 3.7) 4.22–6.66 (– 7.5) cm long. Inflorescences verticillasters arranged in a simple, continuous spiciform inflorescence, (1.0 –) 4.5–10 cm long, terminal or axillary; peduncle 0.5–3 (– 4.5) cm long, densely ferrugineous-pubescent; verticillasters becoming more widely spaced toward the base at anthesis, appearing interrupted, this feature inconspicuous in fruit; verticillasters many-flowered; flowers sessile. Bracteoles ovate-lanceolate to ovate-orbicular, 1–2 mm long, conspicuously shorter than calyx, with 1–2 pairs of lateral veins, densely long-pubescent. Calyx tubular, inflated, ca. 4 mm long, 5 - veined; externally shortly pubescent; inner surface pubescent in upper 2 / 3, glabrous below; teeth narrowly triangular, equal, ca. 1 / 2 as long as calyx tube. Corolla white, ca. 8–9 mm long, exserted 1–1.5 × length of calyx; bilabiate; upper lip 3 - lobed, each lobe marked with purplish-red spots; margins of outer lobes sparsely pubescent, otherwise glabrous; upper lip 6.5–7 mm long; lower lip entire. Stamens 4, erect, strongly exserted; filaments 7–7.5 mm long, inserted ca. 2 mm above base of corolla tube, bearded at middle, beard hairs largely exserted; corolla tube with a fascicle of hairs at point of filament insertion; anthers 1 - locellate, dehiscing apically. Style 7–7.5 mm long; stigma 2 - lobed, lobes subequal, 2.8–3.1 mm long. Disc ca. 0.6 mm long. Nutlets 4, smooth, black, glossy, ca. 0.7 × 0.6 mm, ovate to slightly depressed-globose.</p><p>Distribution and habitat.</p><p>The new species is currently known only from the vicinity of the type locality in Pu’er, Yunnan, China (Fig. 5). It grows in the forest understory near a deep, water-filled gully, with individuals scattered along the gully margin, the only known population of Pogostemon puerensis comprises approximately 30 individuals.</p><p>Etymology.</p><p>Pogostemon puerensis is named after its type locality, Puer Province, China.</p><p>Phenology.</p><p>Flowering from December to February of the following year and fruiting from January to May.</p><p>Vernacular name.</p><p>Simplified Chinese: 普洱刺蕊草 (Chinese pinyin: pŭ ě cì ruĭ căo).</p></div>	https://treatment.plazi.org/id/F5A540793DC1501698D57CD2E973749B	Public Domain	No known copyright restrictions apply.
