Note:—When Gardner (1848) published Meyeria candolleana , he indicated two collections as types, Gardner 2903 and Gardner 4242. We designate the specimen Gardner 2903 at K (K000895290) as lectotype because this specimen is in better condition than its duplicates and the duplicates of Gardner 4242. According to the label information, this latter collection is probably from the adjacent São Domingos municipality, Goiás state, Brazil.

Gardner (1849) mentioned that, after leaving Parnaguá (today Piauí state), he went to the state of Pernambuco towards the town of Rio Preto (today Formosa do Rio Preto, Bahia state), passing over the Batalha mountains. This locality is currently part of the state of Bahia . Therefore, this locality is clarified as the place of origin for the type specimen. Calea crenata (non Calea crenata Chodat 1906: 726 ) and Wedelia oblongifolia are recognized as names pro synonymo by K.H.B. Schultz and J.B.E. Pohl, respectively and considered by Baker (1884) under C. candolleana . According to Reis-Silva et al. (2024), C. candolleana is the most broadly distributed species in this series. It occurs in Bahia , Goiás, Minas Gerais, Mato Grosso, Pernambuco, and Tocantins states in Brazil ( Fig. 2 ).
