Sedum bracteatum Diels, Bot. Jahrb. Syst. 29: 362. 1900, not Viviani (1824); S. amplibracteatum K. T. Fu; S. amplibracteatum var. emarginatum (S. H. Fu) S. H. Fu; S. bracteatum var. emarginatum S. H. Fu.
Herbs annual. Stems 15-50 cm. Proximal stem leaves alternate and deciduous, others 3-verticillate and usually aggregate below inflorescences; pseudopetiole to 1 cm; leaf blade rhombic-elliptic, 3-6 × 1-2 cm, tapered toward both ends, apex attenuate or emarginate to retuse. Cyme corymbiform, often 3-branched, each branch 1-4-flowered; bracts ± orbicular, slightly longer or subequaling flower. Flowers sessile, unequally 5-merous, less often equally 5-merous. Sepals broadly triangular, 0.5-0.7 mm, apex obtuse. Petals yellow, oblong, 5-6 × 1-1.5 mm, midvein inconspicuous, apex subacute. Stamens 10 or 5, slightly shorter than petals. Nectar scales suboblong to oblong-spatulate, 0.7-0.8 mm. Carpels divergent, ca. 5 mm, base connate for ca. 2 mm. Styles long. Follicles 1- or 2-seeded. Seeds fusiform, 2-3 mm, minutely mammillate. Fl. Jun-Sep, fr. Aug-Nov.
Shady moist slopes in forests, rocks on forested mountain slopes; 1100-2800 m. Gansu, Henan, Hubei, Hunan, Shaanxi, Sichuan, Yunnan [Myanmar].
The typical form of this species has the leaf apex attenuate. Collections from Sichuan with the leaf apex emarginate to retuse were treated in FRPS as Sedum amplibracteatum var. emarginatum.
