A new species of Doronicum (Asteraceae, Senecioneae) from central China

The name Doronicum thibetanum Cavill. has been inadvertently applied in herbarium labels to designate a species distributed in central China (provinces of Gansu and Sichuan). However, the study of the type specimen reveals that it is actually a species of Aster. The central Asian species of Doronicum has no available name and is thus here described as D. cavillieri Alv. Fern. & Nieto Fel. This new species has as its closest relatives five central Asian species: D. altaicum Pall., D. briquetii Cavill., D. falconeri C.B. Clarke, D. kamaonense (DC.) Alv. Fern. and D. stenoglossum Maxim. Their morphological affinities and phylogenetic relationships are commented upon and an identification key is provided.
