Morphometry of the Festuca valesiaca agg. in the Istria with the emphasis on F. illyrica Markgr.-Dannenb. delimitation

Possibility of recognition of the species F. illyrica MARKGR.-DANNENB. in the flora of Istria was studied. Precise analysis of species descriptions and the determination key, as well as field work have showed that there are no clear borders between this species and other members of F. valesiaca agg. In the analysis 316 individuals were taken into account and 20 characters were investigated. The data were analysed using multivariate and univariate statistical methods. It was possible to recognise only two groups corresponding with the species F. rupicola HEUFF. and F. valesiaca SCHLEICH. ex GAUDIN. Due to overlappings in the diagnostic characters with F. rupicola, the species F. illyrica could not be recognised as independet entity. The recognition between the species F. rupicola and F. valesiaca is possible only based on quantitative characters The most discriminative character in delimination of F. rupicola and F. valesiaca was the length of stommata.
