replaced synonym: Helichrysum acuminatum DC. nom. illeg.

• Comment: nom. illeg., nom. superfl., as the earliest legitimate name for this taxon at the rank of species is Gnaphalium subundulatum Sch.Bip. (1845). The epithet subundulata was available in Bracteantha in 1991 and thus ought to have been adopted by Anderberg & Haegi under ICN Art. 11.4 (Melbourne Code, 2012).
