“Senecio ucranicus” Besser (1822) versus Senecio ucranicus Hodálová (1999) и Jacobaea borysthenica (Asteraceae): номенклатурное уточнение

Abstract

It is demonstrated that the name “Senecio ucranicus” has never been validated by Besser (1822) because he did not accept that name; moreover, this binomial is non-existing because the word “ucranicus” was not intended as a species epithet. The unnamed species No. 1082 discussed and compared to some other taxa by Besser in his Enumeratio… is identifiable as the currently recognized species Jacobaea borysthenica(Senecio borysthenicus). Consequently, the name S. ucranicus Hodálová (1999) proposed for a Carpathian species of Senecio s. str. is legitimate, and the name S. hercynicus Herborg subsp. ucranicus should be considered a nomenclatural combination with the authorship “(Hodálová) Greuter”. Synonymy of Jacobaea grandidentata is briefly discussed and updated.
