1. Ayapana amygdalina ( Lam.) King & Robinson (1970: 211) .

Eupatorium amygdalinum Lamarck (1786: 408) .

Lectotype (designated here):— PERU. Accurate location not indicated, October 1736, J. de Jussieu s.n. ( P00662867 [digital image!]; isolectotypes P00662866 [digital image!], P00662868 [digital image!]) .

Lamarck (1786) described Eupatorium amygdalinum based on a material collected in Peru by Joseph de Jussieu; however, he did not specify which collection served as the basis for the protologue. In the herbarium of the Muséum National d’Histoire Naturelle (P), three species samples collected by Joseph de Jussieu and incorporated from the Herbarium of Antoine Laurent de Jussieu are deposited under the catalog number “8393”. Later, King & Robinson (1970) proposed a new combination for the species to Ayapana amygdalina ; however, they did not propose any typification for the basionym. In accordance with the International Code of Nomenclature for algae, fungi, and plants (ICN), after analyzing the images of the specimens available in the herbarium of Paris (P), we designate J. de Jussieu s.n. (P00662866; Figure 1 ) as a lectotype, since it is associated with a label with the annotation “ Eupatorium amygdalinum Lam. dict.”, which also includes indistinct and legible spelling, the origin of the specimen as being from Peru, as well that it is from the herbarium of Joseph de Jussieu. The two other specimens, J. de Jussieu s.n. (P00662867, P00662868) are treated as isolectotypes.
