Orchis coriophora s. l. includes a group oftaxa that present a particular morphological and ecological variability which has led to disagreement as to their taxonomic status. With the aim of providing information to help c1arify this situation, morphological data collected over two consecutive years in six populations belonging to the O. coriophora group were statistically analysed. Our resuIts suggest that five ofthe characters studied are oftaxonomic interest (Iower leaf width, second leaf width, mid lobe length, spur length and diameter), some of which had not been previously considered. Finally, some considerations regarding the taxonomic status of these subgroups are discussed.
