Notes —Schlechtendal (1861) indicated a gathering from Argentina by Burmeister for A. quebracho-blanco. However, since the plate presented in its protologue is the only extant element of the original material, we elected it as the lectotype of A. quebracho-blanco. In addition, in order to facilitate the species identification, once the lectotype only presents follicles and seeds, we selected a specimen with leaves, flowers, and follicles as the epitype of A. quebrachoblanco (MBM No. 55705) (ICN article 9.9; Turland et al. 2018). Thus, the lectotype presented here supersedes the neotype designated by Morales (2010).
Also, since Spegazzini & Girola (1910) did not explicitly indicate any gathering in the protologue of A. quebrachoblanco var. pendulum, we understand that this name has no nomenclatural type attached to it. According to the ICN article 9.13 (Turland et al. 2018): “If no original material is extant or as long as it is missing, a neotype may be selected.”. Therefore, we elected a specimen with follicles as the neotype of A. quebracho-blanco var. pendulum (F barcode V0421371F) (ICN article 9.13; Turland et al. 2018). Rojas-Acosta (1913) also did not explicitly indicate any gathering in the protologue of A. quebrachoideum, so, we followed the same criterion to select the neotype of A. quebrachoideum (US barcode 03230109) (ICN article 9.13; Turland et al. 2018).
Lastly, according to the ICN article 26.2 (Turland et al. 2018), infraspecific designations (e.g., “ A. quebrachoblanco f. schlechtendalianum ”) that were intended to include the type of the species to which they were assigned (e.g., A. quebracho-blanco) were not validly published whenever the intraspecific epithets were not the same as the specific.
