Summary Ortiz, S. & Coutinho, A. P.: Achyrothalamus reduced to Erythrocephalum ( Asteraceae, Mutisieae ). – Taxon 50: 389–403. 2001. – ISSN 0040‐0262. The monotypic genus Achyrothalamus has been conventionally distinguished from Erythrocephalum principally by the absence of a pappus and the presence of phyllaries with entire margins. However, a critical re‐examination of 83 morphological and anatomical characters, and a detailed study of the pollen of the two genera, suggest that recognition of Achyrothalamus as a distinct genus is unjustified. We thus propose Achyrothalamus as a synonym of Erythrocephalum with the new combination E. marginatum.
