Morphometric analysis of Croatian and Slovenian populations of Iris sibirica sensu lato (Iridaceae)

Species Iris sibirica L. s. l. in Croatia and Slovenia include populations from lowlands and mountains. The taxonomical status of mountain populations is not clear, although some authors recognize them as a different taxon (Iris erirrhiza Pospichal). As populations variability was detected, but until now not researched, we started with morphometric analyses of populations to detect their possible differentiations. A total of 108 specimens from eleven populations in Croatia and Slovenia were collected. Features for morphometry included: stem length, number of leaves, greatest width of the largest and smallest leaf, length of the largest and smallest leaf, length of the spathe, number of flowers, pedicel length, widths and lengths of falls and standards, length of anthers and filaments, ovary length and length of styles. Relationships between populations and individual plants were analysed by methods of univariate and multivariate statistics. On the basis of investigated features there was no separation of mountain from lowlands populations. The results are in favour of the opinion that both types of population belong to the same species.
