Tipos: "Habitat in America calidiore" (tipo no designado)
Observaciones: Nota al Material tipo.- There appear to be no extant original elements, although Linnaeus provided a short description, and referred to a Plumier polynomial. Grimes (in Brittonia 44: 266-267. 1992) discussed the typification of the name, concluding that it was based on the Plumier element, but he refrained from typifying it because "..Lourteig is preparing a thorough study of Plumier's illustrations". Linnaeus placed the name in the synonymy of M. pennata L. in Sp. Pl., ed. 2, 2: 1507 (1763). [The Linnaean Plant Name Typification Project].
