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) .
