Taxonomie : Dans Flora of Venezuelan Guayana, C. M. Taylor (Berry et al. 2004) commente: "
Guettarda argentea Lam., based on a specimen from “Ile de Cayenne,” French Guiana, may be an older name for this species [
G. macrantha Benth. 1841], but adequate material to confirm this has not been seen." Par ailleurs en 2004, P.G. Delprete identifie un des isotypes (
U0119310) de
G. macrantha comme
G. argentea. Finalement,
Flora do Brasil 2020 traite
Guettarda macrantha Benth. 1841 comme un synonyme de
G. argentea Lam. 1789.
