Comment:
the presumed basionym, "Diazeuxis serrata D. Don", was never validly published, as Don retracted this name later in the same work, thus L. serrata is an illegitimate, superfluous name (Melbourne ICN Art. 52) for Vernonia arctioides Less., which was cited as a synonym and whose epithet ought to have been adopted
