E3E7F0C8DBAB574086AD5DF589D2928D.taxon	diagnosis	Diagnosis. The new species differs from S. makinoi in its usually 2 - branched cymes. S. makinoi also has longer, more erect stems with more internodes (8 – 12 vs. 4 – 8), resulting in denser foliage, whereas the new species has fewer leaves. Key differences include the shape and width of the leaf blades of S. orientalichinense and S. makinoi (obovate to obovate-rhombic vs. obovate to obovate-spatulate; 0.6 – 2.4 cm vs. 0.6 – 0.8 cm), shorter stems (6 – 18 cm vs. 11 – 28 cm), and a usually smaller inflorescence diameter (3 – 10 cm vs. 3 – 15 cm). The new species also has distinct sepals (spatulate-obelliptic vs. linear-spatulate) and nectar scales (broadly cuneate to sub-quadrangular vs. oblong-spatulate). Additionally, our research indicates that S. makinoi is endemic to Japan, which helps to distinguish the two species geographically. The new species can be distinguished from S. baileyi by its robust, slender to sub-woody stems (vs. slender stems) and greater height (6 – 18 cm vs. 3 – 7 cm) (Table 1). Lastly, S. emarginatum is easily identified by its emarginate leaf apex, a feature not found in the other three species (Table 1).	en	Dai, Jing-Min, Xiong, Yu, Li, Pan, Xu, Yue-Liang, Fan, Qiang (2025): A new species of Sedum (Crassulaceae) from eastern China based on morphological and molecular evidence.

E3E7F0C8DBAB574086AD5DF589D2928D.taxon	description	Description. Perennial herbs, fleshy, glabrous, roots fibrous, stems slender to sub-woody, basally prostrate and rooting at nodes, apically erect, usually branched, rarely single, flowering stems sub-erect, with 4 – 8 internodes, usually 2 - branched, rarely 3 - branched, 6 – 18 cm high. Leaves opposite, glabrous, pseudopetiolate; leaf blade obovate to obovate-rhombic, margin entire, 1.3 – 2.7 × 0.6 – 2.4 cm, base tapered and shortly spurred, apex obtuse. Cymes usually 2 - branched, rarely 3 - branched, many flowered, 3 – 10 cm in diam. Bracts resembling stem leaves but obovate and smaller, 0.3 – 2.1 × 0.1 – 1.2 cm. Flowers sessile, equally 5 - merous. Sepals 5, usually equal, rarely subequal, spatulate-obelliptic, 2 – 4 × 1 – 1.5 mm, base shortly spurred, apex obtuse. Petals yellow, base connate for ca. 0.3 mm, 3 – 5 × ca. 1 mm, lanceolate, apex acuminate, hooded. Stamens 10, in 2 whorls, both antesepalous ones and antepetalous ones shorter than petals, the antepetalous stamens fused at base for about 0.5 mm with the petal base, and the antepetalous ones slightly shorter the than antesepalous ones (1.3 – 1.4 vs. 0.9 – 1 cm). Nectar scales broadly cuneate to sub-quadrangular, ca. 0.5 mm long. Carpels 5, lanceolate, 4 – 5 mm long, connate at base for ca. 1 mm, apically usually divergent, sometimes closely connivent. Follicles obliquely divergent, stellate, many seeded, placentation marginal. Styles ca. 1 mm long. Seeds sub-ovoid, mammillate, brown when mature, 0.3 – 0.5 mm long.	en	Dai, Jing-Min, Xiong, Yu, Li, Pan, Xu, Yue-Liang, Fan, Qiang (2025): A new species of Sedum (Crassulaceae) from eastern China based on morphological and molecular evidence.
