Allium sect. Codonoprasum represents an evolutionarily young and rapidly radiating group ofbulbous geophytes, with a significant proportion of polyploids and minor morphological differencesbetween species. In the last 20 years, dozens of new species have been described from the Mediterranean.However, very little new information has been obtained on most of them since their description, especiallyin terms of cytogenetic, molecular and distribution data. Allium goumenissanum is a recently describedspecies of this section, known only from three nearby localities in northern Greece. During the last 10 years,we collected population samples of an unknown species of this section from the southern Balkans, whichseemed to be representative of A. goumenissanum. A variety of methods (cytogenetic, molecular,morphological and micromorphological) were used to compare the populations of an unknown species withthe morphologically similar species A. goumenissanum and A. stamatiadae. AFLP, ITS sequencing andgenome size analyses showed that all populations of the unknown species were in fact A. goumenissanumdistinct from A. stamatiadae. The characterization of the morphology and reproduction of A.goumenissanum is completed, and micromorphological and anatomical characteristics of the leaves of bothspecies are newly published. The distribution of A. goumenissanum, based on new data, now includes amore extensive area of north central Greece, and the species is found as a new taxon for Bulgaria.
