Ainsliaea simplicissima (Asteraceae), a new species from southeast China and its phylogenetic position

Ainsliaea simplicissima M. J. Zhang & H.-Q. Li, sp. nov., a new species (tribe Mutiseiae, Asteraceae) from Fujian, China, is described and illustrated based on morphological and molecular analyses. It can be distinguished by leaves situated in a basal rosette or aggregated at the lower part of the short stem, leaf blade narrowly elliptic or lanceolate, thick papyraceous, and capitulum bearing only one flower. The new species is morphologically similar to A. trinervis and molecularly sister to A. fragrans, both distributed nearby.
