A revision of Taraxacum sect. Erythrosperma (Asteraceae, Crepidinae) in the Republic of Moldova: new species records, chromosome counts and distribution of microspecies
摘要
A revision of the Taraxacum section Erythrosperma in the Republic of Moldova, based on fieldwork and the study of herbarium specimens, has revealed two new species, T. parnassicum and T. persicum, for the country’s flora, confirmation of the occurrence of the sexually reproducing species T. erythrospermum s. str., and records of plants belonging to the T. scanicum group, previously never reliably documented in the Republic of Moldova. These findings are supplemented or supported by descriptions of the species and their distribution, photographs of herbarium specimens, and chromosome numbers and ploidy information. The chromosome number of T. persicum, 2n = 24, is reported here for the first time. An identification key to T. sect. Erythrosperma in Republic of Moldova, compiled based on the newly collected material, is presented.
