Močvirski (Gladiolus palustirs) in ilirski meček (G. illyricus) sta vrsti, ki sta v Sloveniji zavarovani in deležni vedno večje pozornosti na račun njune ogroženosti. Na podlagi dosedanje literature se vrsti lahko zanesljivo ločita le na podlagi podzemnega dela rastline, saj se ovoja gomolja razlikujeta po prepletu odmrlih vlaken. V sklopu te naloge smo podrobneje preučili nadzemni del rastlin in iskali morfološke razlike med mečkoma. V ta namen smo izbrali 61 razlikovalnih, ki smo jih izmerili na 91 rastlinah, nabranih na terenu. Podatke smo statistično obdelali in analizirali ter na podlagi kriterija uporabnosti znakov poiskali najuporabnejše znake za razlikovanje med obravnavanima vrstama. Izdelali smo tudi opise vrst in dihotomni ključ. Ugotovili smo, da se vrsti, poleg razlikovanja na podlagi gomolja, najbolje razlikujeta na podlagi celotne dolžine perigonovih listov, razmerjem med dolžino in širino perigonovih listov, dolžine ploščice in razmerjem med ploščico in žebico posameznih perigonovih listov. Hkrati se razlikujeta tudi v dolžini vratu pestiča ter širini najširšega stebelnega lista. Ugotovili smo, da lahko močvirski in ilirski meček prepoznamo tudi na podlagi dobrega fotografskega posnetka, ki mora vključevati fotografirano socvetje, na katerem je dobro vidna oblika stranskega perigonovega lista zunanjega kroga. Hkrati smo uspeli določiti večino herbariziranih rastlin brez gomolja v herbariju Univerze v Ljubljani. Na podlagi zanesljivih literaturnih podatkov, revizije in naših podatkov smo izdelali karto potrjene razširjenosti obeh vrst.

Sekundarni naslov: Usability of the above-ground distinguishing characters of Gladiolus illyricus and G. palustris (Iridaceae)
Sekundarni povzetek: Marsh (Gladiolus palustris) and wild gladiolus (G. illyricus) are species that are protected in Slovenia and are receiving increasing attention due to their endangerment. Based on the existing literature, these species can be reliably distinguished only by examining the underground part of the plant, as the tunics of the corm differs in the interweaving of dead fibers. As part of this work, we examined the above-ground part of the plants and looked for morphological differences between the marsh and wild gladiolus. For this purpose, we selected 61 distinguishing characters, which we measured on 91 plants collected in the field. We statistically processed and analysed the data, and based on the criterion of character usefulness, we searched for the most useful characters for distinguishing between the considered species. We also produced species descriptions and a dichotomous identification key. We found that, in addition to differentiation on the basis fibrous tunic covering the corm, the two species are best distinguished based on the total length of perigone leaves, the ratio between the length and width of perigone leaves, the length of the limb and the ratio between the limb and the claw of individual perigone leaves. They also differ in the length of the style and the width of the stem leaf. We found that marsh and wild gladiolus can also be identified based on a good photographic image, which must include a photographed inflorescence where the shape of the lateral perigonal leaf of the outer circle is clearly visible. We also managed to identify most of the herbarium specimens without a corm in the herbarium of the University of Ljubljana. Based on reliable literature data and our own data, we created a map of the confirmed distribution of both species.
