Calea martiana Baker (1884: 256–257)

Protologue:—“Minas Geraes, in campis Chapadão do Parana: K. F. P. Martius !; praeterea: Sello 595! ”.

Lectotype (designated here):— BRAZIL. Minas Gerais: K. F. P. Martius 1739 (M [M0147049], digital image!; isolectotype M [M0030078], digital image!).

Note:—Baker (1884) indicated as type specimens the collections by K.F.P. Martius and F. Sellow. The collection number by Martius was not cited in the protologue, but since the chosen lectotype has this number, this data was amended in the type specimen information.

There are two duplicates in the M herbarium. The specimen M0147049 is designated as lectotype because it has more complete label data in agreement with the protologue in comparison to M0030078. The Calea specimen Sellow 595 has not been found.

Reis-Silva et al. (2024) pointed out that C. martiana occurs in Minas Gerais and may possibly occur in Bahia, another state in Brazil.After analyzing several herbaria, we confirm that the species is also found in Bahia [US 3031234] (Fig. 2).
