Calea subg. Meyeria ( Candolle 1836: 670) Baker (1884: 252) .

Meyeria Candolle (1836: 670) .

Type species:— Calea myrtifolia ( Candolle 1836: 670) Baker (1884: 260) .

So far, Calea sect. Meyeria included nineteen species ( Bueno & Heiden 2022a, 2022b). Based on the phylogenetic reconstruction presented in Bueno (2023), the section is redefined with a narrower morphological circumscription proposed here to include shrubs with a cymose capitulescence, bearing capitula with four or more foliaceous outer phyllaries and having the cypsela longer than the pappus. Under this new circumscription, the subgenus comprises nine taxa with eight species ( C. funkiana , C. marginata , C. myrtifolia , C. parvifolia , C. phyllolepis , C. pruskiana , C. subintegerrima , C. triantha ) and one nothospecies ( C. × parviantha ). A monophyletic C. subg. Meyeria requires the exclusion of the following 11 species: Calea arachnoidea , C. chodatii Hassler (1915: 174) , C. grandiflora , C. heteropappa Pruski (1988: 346–347) , C. ilienii Malme (1933: 94–95) , C. kristiniae Pruski (1984: 98–102) , C. monocephala Dusén (1910: 32) , C. nervosa G.M. Barroso (1975: 109) , C. quadrifolia Pruski & Urbatsch (1988: 341) , C. semirii (1998: 698), and C. sessilifolia . These species were moved into another subgenera and sections according to Bueno (2023).

Pruski (2023) resurrected Meyeria and segregated it from Calea based on morphological characters. Based on Bueno (2023), we disagree with the recognition of Meyeria as distinct of Calea and synonymize the species that Pruski (2023) first combined to Meyeria , which are part of Calea . subg. Meyeria .
