Calea bahiensis (Mattfeld) Robinson (1975: 428) ≡ Geissopappus bahiensis Mattfeld (1925: 390)

Protologue:—“ Bahia, Rio de Contas: Casa de Pedra, Campo, P.H.V. Luetzelburg 1, vii 1913 ”.

Holotype:— BRAZIL. Bahia: Rio das Contas, Casa de Pedra, 1919, P. V. Luetzelburg 1 (M [M0030094], digital image!).

Note:—The type specimen collection date indicated in the protologue is July 1913. The year of 1925 written on the specimen’s label may be a later annotation referring to the publication year, since Luetzelburg would have gone to Germany in 1924 and returned to Brazil only in 1927 (Paiva 2003). According to Paiva (2003), Luetzelburg was in Bahia only in 1919, therefore this year is indicated here as the most accurate collection date.

Roque & Carvalho (2011) proposed that C. bahiensis is a synonym of C. candolleana . Here we follow the concepts of Pruski (2013) and Reis-Silva et al. (2024) who accepted this name. It is the only species of C. ser. Candolleanae endemic to Bahia (Fig. 2) (Reis-Silva et al. 2024).
