Gomphrena schlechtendaliana Martius (1826b: 299)

The protologue of Gomphrena schlechtendaliana ( Martius 1826b: 299) includes a detailed diagnosis, and the indication “Habitat in Brasiliae Provincia Cisplatina: Clar. Sellow.”. Holzhammer (1956: 190) reported “Typus: In Brasilia meridionalis, Cisplatina (Sellow) Herb. München”. I found two sheets at M (codes 0241801, and 0241802), both bearing Holzhammer’s annotation, but only one of them (M-0241801) reports the word “typus”. Holzhammer’s statement can be considered as a lectotypification, and the specimen M-0241801 is the lectotype, while the other specimen (M-0241802) is an isolectotype. Further four isolectotypes were traced at P (3 specimens), and BM (one specimen).
