Abstrakt: ABSTRACTThe taxonomic classification of the recently described Lagochilus lorestanicuswithin the genus Lagochilusis traditionally based on its morphological characters. We present here a phylogenetic hypothesis for the genus Lagochilus(Lamiaceae, tribe Leonureae) based on plastid (trnL-trnF and matK) and nuclear (ITS) DNA sequence data, using maximum parsimony, maximum likelihood and Bayesian approaches. Our analysis indicates that while representative species from the Iranian flora are assembled in a sub-clade nested in the clade Spinosi, L. lorestanicusis retrieved in the Acanthoprasiumclade in the tribe Marrubieae. The taxonomic placement of Lagochilus lorestanicusin Acanthoprasiumis also corroborated by re-examination of morphological characters. Consequently, the species is transferred to the genus Acanthoprasium, which was previously restricted to Italy and France (i.e. A. frutescens) and Cyprus (i.e. A. integrifolium). The intra-specific morphological variations as well as the conservation status of Lagochilus lorestanicusare discussed.
