Sinoseneciotongziensis (Asteraceae), a new species from north Guizhou, China.

Abstract

Sinoseneciotongziensis 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.globigervar.adenophyllus.
