Santolina ageratifoliaBamades ex Asso ( Compositae ) and their relationships withS. rosmarinifoliaL.

[摘要] The status ofSantolina ageratifoliaBamades ex Asso as a distinct species belonging toS. rosmarinifoliaL. aggr. is vindicated. An historical approach, a revisión of the diagnostic characters and a detailed chorology of the species in Spain is presented. Likewise, some doubtful questions conceming taxonomy and chorology in Spain of the whole aggregate (includingS. rosmarinifoliaL. s. str.,S. canescensLag.,S. pectinataLag. andS. semidentataHoffmanns. & Link) are clarified. A new nomenclatural combination is proposed:S. semidentatasubsp.melidensis(Rodríguez-Oubiña & Ortiz) López Udias, Fabregat & Mateo.
