New localities of endemic Aquilegia kitaibelii Schott and Cardaminopsis croatica (Schott, Nyman et Kotschy) Jáv. in Croatia

New localities of two endemic, rare and floristically interesting species in the north-western Dinaric Mountains in Croatia are reported in the paper. Both species are statutorily strictly threatened species in Croatia. Aquilegia kitaibelii Schott is as a rare, endemic species included in Appendix II of the Habitats Directive (NATURA 2000 Species) and in the IUCN list as data deficient (DD) species. New localities of A. kitaibelii were found on Mt Obruč and central and south section of Mt Velebit, while new localities of Cardaminopsis croatica (Schott, Nyman et Kotschy) Jáv. were discovered on hills in the Gacka Region and the cenral section of Mt Velebit. In general, both species grow mainly from fissures on rocks together with other petrophilous plant species. It was also noted that A. kitaibelii grows on screes. In Gacka Region C. croatica grows in thermophilous habitats, that is, on rocks with different expositions, together with thermophilous sub-Mediterranean species and with some mountain species of common beech and silver fir forests. In the central section of Mt Velebit, C. croatica also grows in a thermophilous community of forest rocks as well as in anthropogenic habitats, like the edges of gravel roads. These observations suggest the ecological adaptability of that endemic species.
