AF7AEE554F6E7B1AFF02F9BA64E54CE5.taxon	diagnosis	Diagnosis: — Youngia jianningensis is similar to Y. heterophylla, but differs from the latter in having slender stems 20.0 – 55.0 cm tall (vs. thick stems 30.0 – 110.0 cm tall), basal leaves usually orbicular, ovate to elliptic, or hastate (vs. oblanceolate-elliptic), undivided, more rarely lyrately pinnatipartite or pinnatisect as the stem leaves (vs. lyrately pinnatisect) with lateral lobes in 1 – 4 (vs. in 1 – 8) pairs. It is also similar to Y. jiulongshanensis, but can be easily distinguished by 11 ‒ 14 (vs. 5 – 7) florets per capitula, 8 (vs. 5) inner phyllaries, corolla 8.0 – 8.5 mm (vs. 7.0 ‒ 8.0 mm) long.	en	Chen, Yong-Bin, Zhou, Cheng-Yuan, Gao, Yuan-Long, Ma, Liang, Lin, Feng, Chen, Shi-Pin (2025): Youngia jianningensis (Asteraceae), a new species from China: evidence from morphological and DNA analyses.

AF7AEE554F6E7B1AFF02F9BA64E54CE5.taxon	distribution	Distribution and habitat: — The species is mainly distributed in Xiyuan Town, Jianning County, and scattered found in Taining County, northwestern Fujian Province, China. It grows on moist rocky soil in hilly areas or Danxia landforms at altitudes of 600 – 700 m (Figure 5). In Jianning County, this species grows sporadically and sparsely along roadsides on moist rocks, over about 500 m and with approximately 200 individuals, making this area the core habitat of this new species. In Taining County, it is restricted to isolated individuals (1 – 2 plants) within the Danxia landforms. Based on the current data, this species should be classified as Endangered (EN) according to the IUCN guidelines (IUCN Standards and Petitions Committee 2022), due to its restricted distribution with the number of known mature individuals in the wild population being less than 250.	en	Chen, Yong-Bin, Zhou, Cheng-Yuan, Gao, Yuan-Long, Ma, Liang, Lin, Feng, Chen, Shi-Pin (2025): Youngia jianningensis (Asteraceae), a new species from China: evidence from morphological and DNA analyses.
