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.
