Popis: The aim of the study was to confirm the hybridogenous status of several populations of putative Serapias × todaroi along the eastern Adriatic coast, and identify the most useful morphological traits for recognizing the hybrid in the wild. We have performed a karyological study, and compared the morphology of the hybrids with the assumed parental species S. lingua and S. parviflora. The intermediate features of the studied populations, particularly chromosome number and shape of the base of the labellum, strongly support its hybridogenous origin. Although morphometric analysis found certain traits of the hybrid to be intermediate with respect to the parental species, in general the hybrid plants closely resembled S. lingua. The flowers of the hybrid were mostly influenced by S. lingua, while the vegetative traits were mostly influenced by S. parviflora. To distinguish the hybrid in the field successfully, most attention should be paid to the shape of the base of the labellum and plant height, while flower size (particularly of labellum) can also be useful to some extent.
