R. Luo, A. Liu & H. Sun 2026	<div><p>Ceropegia gengmaensis P. R. Luo, A. Liu &amp; H. Sun sp. nov.</p><p>Figs 1, 2, 4</p><p>Diagnosis.</p><p>Ceropegia gengmaensis shows affinities with C. salicifolia and C. dolichophylla, both of C. sect. Chionopegia. It differs from C. salicifolia by its erect to sprawling habit (vs. twining), elliptic leaves 2.0– 5.5 cm (vs. lanceolate, 6–15 cm), densely pubescent stems bearing usually solitary flowers (vs. glabrous stems with sessile cymose many-flowered inflorescences), and narrower corolla lobes with only slight expansion above the throat (vs. lobes longer and wider, upper portion markedly expanded). From C. mairei it differs by the much less pronounced basal inflation of the tube (vs. a strongly inflated tube) and an annular ring of white hairs at the mouth of the basal inflation (vs. inner surface of the basal inflation with dense white hairs). Compared with C. dolichophylla, C. gengmaensis is erect to sprawling and shorter (up to 30 cm) with pubescent stems, whereas C. dolichophylla is a twining or climbing vine (up to 1.5 m) with glabrous stems and much longer, narrowly lanceolate leaves. They also differ markedly in floral morphology: in C. dolichophylla the corolla lobes are pilose inside, often with conspicuous marginal vibratile hairs; whereas in C. gengmaensis hairs are mainly restricted to a distinct annular ring at the mouth of the basal inflation of the tube.</p><p>Type.</p><p>China • Yunnan Province: <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=99.100006&amp;materialsCitation.latitude=23.6" title="Search Plazi for locations around (long 99.100006/lat 23.6)">Lincang City</a>, Gengma County, 23°36'00"N, 99°05'60"E, 1200 m, 11 May 2025, P.

Roots 8–12, white, fleshy, fusiform, fascicled, 80–200 × 2–6 mm. Stem slender, terete, greenish or brown, 1–2 mm thick, uniformly finely puberulent; internodes 10–40 mm long. Leaves opposite; petiole terete, 10–15 × ca. 1 mm, finely pilose, adaxially grooved; blade elliptic, 20–55 × 10–25 mm, adaxially green, densely puberulent, abaxially green, pilose along midvein, base cuneate, acute; midvein adaxially flat or slightly depressed; lateral veins in 1–4 pairs, obliquely ascendant, adaxially flat, abaxially slightly convex. Flowers 1–2, extra-axillary; subsessile; pedicel 5–10 × 1 mm, finely pilose; bracts 3–5, subulate to lanceolate, 2–4 mm long, greenish, acuminate at apex. Sepals 5, subulate to lanceolate, 3.0–5.0 × 0.5–1.0 mm, acuminate at apex, glabrous. Corolla tubular, 30–50 mm long tube 15–20 × 3–5 mm, outside reddish-purple, glabrous, inside with reddish-purple longitudinal stripes otherwise white except for reddish-purple upper third, white hairs in mouth of basal inflation, otherwise glabrous; basal inflation ovoid, 5–10 × 3–5 mm, gradually narrowed and increasing from the middle to 5–10 mm at mouth, ± 1.5 times as wide as the basal inflation; lobes 1.0–15.0 × 1.0–3.0 mm, red outside, white inside except for reddish-purple apical third, strongly longitudinally folded outwards along midrib exposing white inner surface with white hairs; outer coronal lobes ca. 2.0 × 1.0 mm, orange, deeply divided into two triangular, cuspidate teeth, with few white hairs on the inner surface; inner coronal lobes linear-ligulate, ca. 3.5 × 0.8 mm, light translucent yellow, apices convergent but not fused, slightly recurved. Pollinia orange, ovoid, ca. 0.25 × 0.30 mm.
