A taxonomic revision of Taraxacum sect. Erythrosperma (Compositae‐Lactuceae) in Corsica

Taraxacum sect. Erythrosperma (H. Lindb.) Dahlst. in Corsica was revised on the basis of a detailed study of old collections used by J. L. van Soest in his first studies of the genus in Corsica, and new collections and cultivations. All the names based on the specimens from Corsica are interpreted, 16 species of the section are recognized. Particular attention was paid to a group of the sect. Erythrosperma with a number of endemics or subendemics, around T. purpureomarginatum. Four new species are described. A number of names are newly interpreted and typified. All the specimens studied are cited, with the exception of taxa common in Europe. All the species of the sect. Erythrosperma known from Corsica are agamospermous; ten species proved to be triploid or tetraploid. All the taxa endemic to, or having a substantial part of their distribution range in Corsica are given full description. (© 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
