F06FED76666B3668FF7AAAF0BF33F87C.taxon	diagnosis	Diagnosis: — Sedum yangjifengensis resembles S. makinoi Maximowicz (1888: 487) during the vegetative growth period by having opposite leaves, but has slender, tufted stolons, and during the reproductive growth period, has very long internodes below the inflorescence and much greater variation on leaf size, in which the bract leaves of inflorescence are the largest ones. In reproductive period, it is similar to S. concarpum FrÖd (1935: 122) and S. lipingense by having long internodes, but has stolons, connate follicles only at 1 mm and no rosette leaves present.	en	Zhu, Zong-Wei, Le, Xin-Gui, Li, Lu-Fei, Chen, Shi-Pin, Chen, Bin (2023): Sedum yangjifengensis (Crassulaceae), a new species from Jiangxi, China.

F06FED76666B3668FF7AAAF0BF33F87C.taxon	description	Description: — Biennial or perennial fleshy herb, glabrous throughout the entire plant. Roots fibrous. Sterile stems creeping, clustered, 0.5 – 1 mm in diam., 5 – 30 mm long, internodes up to 10 mm long when shaded. Flowering stems grow out from the top or leaf axils of vegetative stems, seldomly branched at the base, erect, 7 cm to 15 cm high, 1 – 3 mm in diam., internodes 1 – 4 cm long. Leaves many pairs on vegetative stems, opposite; petioles 2 – 3 mm long; leaf blades 5 – 8 mm wide, suborbiculate or spatulate, margin entire, base rounded, rarely truncate, apex rounded. Leaves 1 – 3 pairs on flowering stems, opposite or seldomly alternative on upper part, 2 – 4 clustered on the top of the branches form into bract leaves of the florescence; leaf blades turn larger form the base to the top of the branches, 5 – 12 mm wide, 10 – 20 mm long, elliptic or obovate, entire, apically rounded and sinuate, base attenuate into shot petiole with short broad spur. Cyme 3 – 5 — branched, corymbiform, 3 – 6 cm diam., few flowered. Flower bracts similar with the inflorescence ones but gradually turn smaller. Flowers sessile, mostly 5 - sometimes 4 - or 6 - merous; sepals uneven in size from 1 mm to 2 mm wide and 2 mm to 4 mm long, with a rod or spoon shape, rounded and thick on the top; petals yellow, lanceolate, 5 – 6 mm long, 1.5 mm wide at the middle, acuminate to apex, abaxially raised into ridge and apically 0.5 mm protruding into a horn shape; stamens in two whorls, with the antepetalous stamens inserted about 1 mm from the petal base. The nectar scales inverted trapezoid, about 0.5 mm long, 0.5 mm wide. Carpels narrowly ellipsoid, ca. 5 mm, base connate ca 1 mm; styles 1.5 – 2 mm. Follicles stellately divergent, many seeded. Seeds narrowly ovoid, about 0.8 mm long, brown papilliferous.	en	Zhu, Zong-Wei, Le, Xin-Gui, Li, Lu-Fei, Chen, Shi-Pin, Chen, Bin (2023): Sedum yangjifengensis (Crassulaceae), a new species from Jiangxi, China.
