Taxonomic notes on the Angianthus drummondii complex (Asteraceae : Gnaphaliinae)
KEIGHERY, G.J.
Angianthus drummondii is revised and shown to be a species complex of three allopatric species. The complex comprises A. drummondii (Turcz.) Benth., an erect plant with long inflorescence bracts confined to fresh water clay-based wetlands; A. platycephalus Benth., a prostrate plant with short broad inflorescence bracts, growing in fresh to brackish clay soils, is resurrected; and a new species A. halophilus Keighery, an erect plant with short inflorescence bracts, found on gypsum soils, is described.
