A rare moss Buxbaumia aphylla was only recently found in Croatia. Here we report five new localities, one from Dilj Gora and four from Mt. Papuk. Small populations on bare acidic soil within the forest and along the forest edges were registered.

Pasji zub ( Erythronium dens-canis L.) široko je rasprostranjena proljetnica čija je boja ocvijeća u većini populacija u Hrvatskoj ružičasta, dok su bijelocvatuće varijante obično rijetke i ojedinačne. Od sredine 19. stoljeća postoje zapisi o bijelocvatućim populacijama u dolini Jagodnjak na Požeškoj gori, a neobična boja pripisivala se pedološkim i geološkim čimbenicima. Tijekom proljeća 2025. godine intenzivno se kartiralo populacije na toj gori, s ciljem utvrđivanja distribucije bijele i ružičaste varijante, pronalaska zone kontakta te usporedbe boje cvjetova s geološkom podlogom.

Galanthus reginae-olgae Orph. occurs in mainland Greece, the Ionian Islands, Corfu, Albania, Italy, Sicily, Montenegro, Bosnia and Herzegovina, and Croatia. This paper aims to extend the knowledge of the distribution and ecology of G. reginae-olgae in Croatia and the northwestern Balkans. A field study in 2023 revealed as many as 35 populations in southern Croatia, some of them counting up to 100.000 individuals. Most of the populations exhibit semi-sciophilic behaviour within transitional habitats (ecotones) from insolated grassland to shaded eu- and sub-Mediterranean thickets and forests, and are found in the altitudinal range from sea level to 664 m a.s.l., at an average distance of 5.44 km from the coastline. Analysis of the bioclimatic variables reveals that the populations studied find an optimum in Mediterranean conditions with a mean annual air temperature of 14.61 °C and mild winters. The annual precipitation is high, exceeding 1600 mm, although it is limited to the winter period. The analyses of the temperature data provided insight into the environmental conditions that might serve as triggers for the initiation and duration of anthesis. In view of the the observed leaf length and flowering time, the populations are designated G. reginae-olgae subsp. vernalis Kamari. Since the Croatian populations are sparsely scattered along the northern limit of the species’ distribution on the Balkan Peninsula, future research should investigate the adaptability of this species to habitat and climate changes in the eastern Mediterranean region.

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.
