Abstract
In this article we present the new species Crocus cobbii from the northwestern part of the Iberian Peninsula. The definition of Crocus cobbii is based on molecular and detailed morphological findings, including the molecular examination and morphological revision of its four relatives, C. nudiflorus, C. clusii, C. salzmannii, and C. serotinus. An epitypfication for C. serotinus was done and a lectotype for C. nudiflorus designated. In addition, our molecular data assign the origin of the English C. nudiflorus, from which the plant was originally described, to the eastern Pyrenees.
