Notes:—In the protologue of M. graveolens, De Candolle (1828) cited that he examined a Martius specimen (v.s. in h. Mart.). There is a sheet at M with a description of Rhexia graveolens handwritten by Schrank and Martius attached (Fig. 6), which should be considered the holotype of M. graveolens.
In the protologue of M. leucantha, Naudin (1849) indicated a collection made by Weddell in Brazil. Since there are two sheets at P (Weddell 2560), we designated the sheet with a short description and drawing made by Naudin as the lectotype of M. leucantha.
Cogniaux (1883) described M. leucantha var. purpurea to include specimens with purple to purple-violet flowers. In the protologue of M. leucantha var. purpurea, Cogniaux (1883) cited Glaziou 14720 at Herb. Eichl. According to Stafleu & Cowan (1976), the types of South American from A.W. Eichler (1839–1887) are mainly at B, destroyed during World War II (see Hiepko 1987), but a part at M and G. Duplicates were only seen at BR, K, P, and R. The material at BR was chosen as the lectotype because the vegetative and reproductive parts correspond to the protologue description, it is in good condition, and BR was the home institution of Cogniaux. In the protologue, Cogniaux (1883) mentioned that the specimen was collected in Rio de Janeiro, but in the suppressed work “Liste des plantes du Brésil Central recueillies en 1861–1895”, Glaziou (1908) noted that Glaziou 14720 is from Ouro Preto, in Minas Gerais state. In fact, the specimen Glaziou 14720 at P has the annotation “Ouro Preto (campo de S. Sebastião)” handwritten by Glaziou, whereas the specimen from BR does not bear information as to where it was collected. Microlicia graveolens is endemic to Minas Gerais state (Romero et al. 2020), occurring in the Espinhaço Range and, up to now, there is no record for Rio de Janeiro state. Certainly, this is also indicative of erroneous data from Glaziou collections (see Wurdack 1970).
The original description of M. graveolens matches with the morphology of M. seringeana, M. hilariana, M. leucantha, and M. leucantha var. purpurea; therefore, we propose them as synonyms of M. graveolens.
