A new locally endemic species of Euphorbia sect. Esula (Euphorbiaceae) from Steinfeld, Lower Austria
In the study we (i) used RADSeq data to determine if the Austrian E. caesia is really conspecific with the Asian E. caesia or if it is a different species and (ii) to ascertain if gene flow occurs between E. caesia and the sympatric E. esula and E. cyparissias in Lower Austria.
