Abstract
Although the flora of Croatia is rather well known, several new Carex species and hybrids were able to be added during a caricological visit to Croatia and after two more years of fieldwork (2023–2024). The total number of Carex species is now 91; besides, there are eleven Carex hybrids known. During our herbarium research and revision in several European herbaria, and recent fieldwork, five new Carex taxa for Croatia were found: C. distachya subsp. phyllostachioidea, C. depressa subsp. transsilvanica, C. nigra subsp. juncea, C. pairae, and C. secalina, while C. aterrima subsp. aterrima was overlooked on the previous Croatian national list. In addition, eleven hybrids were found that were new for Croatia: C. × alberti, C. × alsatica, C. × auroniensis, C. × leutzii, C. × oberrodensis, C. × oenensis, C. × prolixa, C. × pseudoaxillaris, C. × subviridula, C. × villacensis, and C. × xanthocarpa. Moreover, several rare Carex species were confirmed at known locations and new localities were detected for multiple species. The following species were involved: C. atrata, C. buekii, C. capillaris, C. cespitosa, C. fritschii, C. illegitima, C. lasiocarpa, C. pulicaris, C. punctata, C. randalpina, C. rupestris, and C. vulpinoidea. Carex limosa has to be considered as extinct from Croatia. Search for the species C. arenaria, C. diandra, C. frigida, C. melanostachya, C. pauciflora, C. stenophylla, and C. supina, has revealed only very old herbarium specimens, but there has been no recent confirmation in the field. For C. dioica there was no material available, nor could it be confirmed in the field. Two hybrid names, C. × rossiana and C. × villacensis, are lectotypified here
