Notes — Ducke (1922) validly published A. duckei discovered by Huber (1910) after presenting Huber’s diagnosis (in sched.) along with other information. He attributed to Huber the species authorship ( Ducke 1922).

Among the five gatherings indicated in the protologue of A. duckei, Woodson (1951) cited “Ducke 11040” (Ducke s.n., herbarium MG No. 11040) as the type. Since the number “11040” corresponds to a voucher of a single specimen in MG (MG barcode MG011040), as explained by Ducke himself in the publication’s introduction: “The specimen numbers cited in this work refer to the Museu Paraense, whenever there is no special indication” (“La numération des spècimens d’herbier cités dans ce travail se refère a l’Herbier Amazonien du Museu Paraense, chaque foi qu’il n’y a pas d’indication spéciale.”; Ducke 1922, p. 19), we understand that Woodson (1951) performed the lectotypification of A. duckei .
