ABSTRACT A new species of Asteraceae from Taiwan, Senecio kuanshanensis C.-I Peng & S.W. Chung, a distinct member of sect. Crociseris (Reichenb.) Hall. & Wohlf. ser. Nemorenses Gagnidze, is described and illustrated. Senecio kuanshanensis is apparently rare, presently known only from mountain ridges of Kuanshan, at (2,500-)3,000-3,300 m elevation in the southern part of the Central Mountain Range of Taiwan. In habit the new species somewhat resembles S. morrisonensis Hayata, an endemic congener from Taiwan, but it is clearly distinct in having longer peduncles (3-7 cm vs. 0.5-2[-3] cm), longer involucres (8-10 mm vs. 4.5-6 mm), longer corolla tube in the disc florets (4-5 mm vs. 3-3.5 mm), longer rays (9-14 mm vs. 5.5-7.2 mm) in the ray florets, and median cauline leaves that are deeply bipinnatipartite to tripinnatipartite (vs. serrate to coarsely dentate or deeply pinnately lobed).
