Morphological and ecological diversification of Conocephalum conicum complex in Japan and Taiwan

Abstract

Based on DNA haplotype and morphology analyses, 3 separate species of Conocephalum conicum s. lat. and C. salebrosum had been recognized in Japan and Taiwan by Akiyama and Odrzykoski (2020), and are described here. Morphological features and patterns of distributional areas for the 4 species, including 3 new taxa, C. orientalis H. Akiyama, C. purpureorubrum H. Akiyama, and C. toyotae H. Akiyama (formerly recognized as C. conicum J, F, and R types, respectively) as well as pan-boreal C. salebrosum are described in detail.
