The specific epithet of Saussurea frolowii is spelled in the protologue with a "w" (except on the accompanying figure, which, however, does not have nomenclatural impact), whereas the sectional and hence the generic names are spelled with a "v." As both spellings are transcriptions from a Russian personal name, the former in German and the latter in Latin, they cannot be treated as correctable errors but have to be accepted as they are.
