Calea gardneriana Baker (1884: 255) ≡ Meyeria angustifolia Gardner (1848: 414)

Protologue:—“Bushy places near Villa de Natividade, Province of Goyas. April, 1840, G. Gardner 3282 ”.

Lectotype (designated here):— BRAZIL. Goiás [Tocantins]: Natividade, bushy places, Jan. 1840, G. Gardner 3282 ( BM [ BM001009793 ], digital image!; isolectotypes P [ P020140718 ]!; P [ P020140719 ]!; P [ P020140720 ]!; US [US1802953]!; W [ W0043959 ], digital image!).

Note:—Baker (1884) published the new name C. gardneriana , based on Meyeria angustifolia , since the specific epithet “ angustifolia ” was already preoccupied by Calea angustifolia Gardner (1848: 417) . There are several duplicate specimens from the gathering Gardner 3282. The specimen BM [001009793] was chosen as a lectotype because, among the syntypes, this is one of the few that contains a label indicating that the material was collected in Natividade. The other is a specimen that was kept in the herbarium at K [000895286], however the material deposited in the BM herbarium was prioritized because the label has information more consistent with the protologue as to the date of collection.

Calea gardneriana occurs ( Fig. 2 ) in Bahia , Goiás, Maranhão, Mato Grosso, and Tocantins states ( Reis-Silva et al. 2024). We recorded the occurrence of this species in Maranhão state [EAC5924] for the first time.
