Abstract

Sinosenecio tongziensis R.B.Zhang, Tan Deng & Ying Liu (Asteraceae), a new species from Tongzi County in northern Guizhou, China, is described and illustrated. It closely resembles S. changii in the subscapigerous habit, ovate-oblong and pinnately veined leaf lamina, and simple to compound terminal corymbs, yet differs markedly by the texture of leaf lamina (membranous vs. papery), the number of lateral veins (8–10 vs. 10–18), and the indumentum on the stems, leaves, and inflorescences (pubescent with 2–5 mm long, uniseriate, spreading hairs vs. sparsely white arachnoid to densely white tomentose). Phylogenetic analysis indicates that S. tongziensis is related to S. bodinieri, S. nanchuanicus, S. confervifer, and S. globiger var. adenophyllus.
