Several hybrids from Papuk – rare or new taxa in the national flora

Four hybrid taxa, previously rarely, or now for the first time recorded in Croatia, observed during the spring of 2020 and 2022 on Mt. Papuk, are presented. A hybrid of Primula vulgaris Huds. and P. veris L. called P. × polyantha Mill. is known as an ornamental plant, which comes in a whole palette of colors, but the occurrence of spontaneous hybrids that occur in nature in Croatia has been discussed in print only once, by Degen in 1937. Ophrys × hybrida Pokorny ex Rchb. f. is a cross between O. sphegodes Mill.and O. insectifera L., and it has never previously been recorded in Croatia. Orchis × beyrichii (Rchb. f.) A. Kern. and O. × angusticruris Franch are rarely recorded hybrids in which O. simia Lam. participates, the first by crossing with the species O. militaris L., and the second with O. purpurea Huds.
