Current-year branches gray-white, glabrous.  Leaves: Alternate; thinly leathery, elliptic, 6.5–12.5 cm long, 3.5–5.5 cm wide; apex short-acuminate or acute, base cuneate to broadly cuneate; upper 2/3 of margins sparsely serrate; adaxial surface green, abaxial surface pale green with sparse yellowish-brown glandular dots; lateral veins connected near the margin on the adaxial surface, prominent and forming an arching venation network on the abaxial surface, glabrous. Petiole 7–12 mm long, grooved adaxially. Flowers: 1–2 axillary or terminal, yellow to pale yellow, fragrant, 4–6 cm in diameter; pedicel 6–10 mm long. Bracts 4–6, leathery, ovate, 0.5–2.0 mm long, glabrous externally, pubescent internally, margins finely ciliate. Sepals 5, leathery, ovate, ca. 5 mm long, glabrous externally, densely white-sericeous internally, margins ciliate. Petals 7–9, membranous, obovate-elliptic, 1.5–2.5 cm long, 1.5–2.0 cm wide, glabrous, basally connate for 3–4 mm, apex rounded. Stamens in multiple whorls, arranged in 4 clusters, ca. 1.5 cm long, basally adnate to petals for 4–5 mm; outer filament whorls 1/3 connate; anthers yellow. Ovary 3-loculed, oblate-spheroid, 2–3 mm in diameter, glabrous on lower half, white-pubescent apically; styles 3, free at apex, glabrous, ca. 18 mm long.  Fruit: Capsule, oblate-spheroid, 4.5–6.5 cm in diameter, glabrous; pericarp 9–11 mm thick. Seeds: 1–2 per locule, subglobose, 1.4–1.8 cm in diameter, brown, densely covered with brown, long filamentous hairs.  

Phenology: Flowering period: mid-October to December; fruiting period: September to November of the following year.  

Distribution and Habitat: This species is endemic to Luxiong Village, Ceheng County, Guizhou Province, with a wild population of just over 40 individuals. It grows in the understory of evergreen broad-leaved forests within sandstone rocky mountain valleys at elevations around 660 m.  

Note:C. tianeensis should be recognized as a distinct species. It differed from C. huana primarily in the flowering period from February to April (vs. mid-October to December),and the color of annual branch ranged from light red to burgundy(vs. grey),and its fruit was oblate triangular spherical-shape with pericarp of 1-3 mm thick(vs. fruit oblate spherical-shape with pericarp of 9-11 mm thick) .

查阅的其他标本:中国,贵州省册亨县路雄村,199710月,杨成华2951SYSGF),有花有 果;同地,2011912日,杨成华9240GF),有花有幼果;同地,2018111日,杨成华539 IBKGF),有花有果;同地,202010月,杨成华 6786GF),有花有果。 本种近似于天峨金花茶,但该种当年生枝灰白色(vs. 紫红色);蒴果直径4.0~6.5 cmvs. 2.5~ 4.1 cm);果皮厚9~11 mmvs. 1~3 mm);花期10月 中旬~12月(vs. 2~4月)。

重要区别特征:天峨金花茶 (C. tianeensis) 应恢复成一个独立的物种, 其与贵州金花茶的区别主要在于, 该种花期 2—4月 (vs. 10月中旬—12月), 当年生枝淡红至紫红色 (vs. 灰白色), 果实扁三角状球形, 果皮厚 1~3 mm (vs. 果实扁球形, 果皮厚 9~11 mm)。
