Typification and nomenclature of the names in the Santolina chamaecyparissus species complex (Asteraceae)

Abstract

A nomenclatural revision of the Santolina chamaecyparissus species complex is presented. A detailed survey of original material for all names applied to members of the complex was performed, and 28 names are newly typified. The current usage of the names S. villosa and S. ericoides, relating to some Spanish and French populations, is discussed. The name S. villosa is applied to a taxon endemic to Spain, whereas S. ericoides is applied to those Spanish and French populations often traditionally referred to S. villosa.
