Herbs perennial, acaulescent. Leaves basal, 20–35; petiole cylindrical, densely extremely short pubescent, 5–7 × 0.4–0.5 cm; leaf blade elliptical to slightly ovate, 5.5–7.5 (–9) × 3–5 cm, densely appressed puberulent, base cuneate, margin entire, apex acute; lateral veins 4–6 on each side of the midrib, conspicuous on the abaxial surface, inconspicuous on the adaxial surface. Cymes 4–6, axillary, 1–3-branched, 2–8-flowered; peduncle 5–10 cm long, 1–1.5 mm in diameter, densely erect puberulent; bracts 2, opposite, linear, 3–3.5 × 1 mm, puberulent. Pedicel 1.5–2 cm long, 1–1.5 mm in diameter, puberulent. Calyx 5-parted from the base; segments equal, lanceolate-linear, 3.5–4 × 1–1.2 mm, densely pubescent, margin entire, apex acute. Corolla pale yellow, throat with two distinctly elliptic yellow spots, 2.5–3 cm long, orifice 0.6–0.8 cm in diameter, outside puberulent with both glandular and eglandular hairs, inside glabrous; tube narrowly infundibuliform, 1–1.2 cm long; limb distinctly 2-lipped, adaxial lip 2-parted to the base, lobes slightly oblique linguiform or ovate, ca. 5 × 2.5 mm; abaxial lip 3-parted to the middle, lobes obliquely ovate, ca. 8 × 4 mm. Stamens 2, adnate to ca 1.0 cm above the corolla base; anthers purple, reniform, ca. 1.5 × 1.2 mm, slightly constricted at the middle; filaments geniculate close to the base, ca. 6 mm long, glabrous; staminodes 3, lateral ones short linear, glabrous, 1–1.2 mm long, adnate to 4–5 mm above the corolla base, the central one linear, 0.8–1 mm long, adnate to 2.5–3 mm above the corolla base. Disc annular, margin entire or sometimes slightly erose, ca. 0.7 mm high. Pistil 1.4–1.8 cm long; ovary linear, 3–4 mm long, 1–1.5 mm in diameter, densely puberulent with both glandular and eglandular hairs; style 1.1–1.4 cm long, ca. 0.5 mm in diameter, glandular-puberulent. Stigmas translucent to white, obtrapeziform, apex 2-parted up to the middle, 0.8–1 mm long. Capsule linear, 1.8–2 cm long, ca. 1.5 mm in diameter, puberulent with both glandular and eglandular hairs.

Huáng Huā Hé Chí Bào Chūn Jù Tái (Chinese pronunciation); 黄花河池报春苣苔 (Chinese name).
Geographical distribution of the
The type population consists of approx. 3000 mature individuals, all growing on moist and shaded rocky surfaces on the cliff. They are easily disturbed by human activities because the distance from the type locality to the local village is short. Parts of vegetation of the type hill have been cleared by local people for fruit trees cultivation. Thus, following the IUCN Red List Categories and Criteria (
