| Résumé : |
"The Euro-Siberian complex ofRanunculus auricomus(Ranunculaceae) consists of about 800 mainly apomictic and polyploid taxa. So far, only four sexual species have been described (R. carpaticolaSoó,R. cassubicifoliusW. Koch,R. notabilisHörandl & Gutermann and R. marsicusGuss. & Ten.). With the exception ofR. marsicusand rare autotetraploids ofR. cassubicifolius, sexuality seems to be linked to diploidy. Using flow cytometric ploidy estimation, flow cytometric seed screen and pollen quality, six new diploid sexual species have been revealed in C France, C and SE Slovenia and Croatia:Ranunculus austroslovenicusDunkel,R. calapiusDunkel,R. cebennensisDunkel,R. mediocompositusDunkel,R. peracrisDunkel andR. subcarniolicusDunkel. Here, they are described and depicted in detail. Sexual reproduction has been verified forR. austroslovenicus, R. cebennensis, R. subcarniolicusand also for the previously describedR. envalirensisGrau andR. flabellifoliusHeuff. ex Rchb."
