Notes — Rusby (1920) indicated the collection Smith 836 in the prologue of A . ellipticum . However, since the same collecting number was used for two different gatherings, corresponding to specimens with follicles (“Bonda, in February”) and flowers (“Masinga Vieja, April 25”), we chose as the lectotype collection of A . ellipticum the gathering with flowers and the specimen from the herbarium NY as the lectotype since it belongs to the herbarium where Rusby worked (ICN article 9.3; Turland et al. 2018 ). Also, Rusby (1920) mentioned that the preparations of Smith 836 would contain a mixture of species ( A . decipiens and A . ellipticum ). Still, we disagree with that since the characteristics of A . decipiens and A . ellipticum overlap with those of A . cuspa , such as the leaves with reticulodromous venation, leafopposed inflorescences, and basal or apical seed nuclei. Müller-Argoviensis (1860b) indicated the gathering Spruce 3617 in the prologue of A . decipiens but did not cite in which herbarium the type would be deposited. Thus, we chose a specimen with mature inflorescences from this collection as the lectotype of A . decipiens (K barcode K000587706) (ICN article 9.3; Turland et al. 2018 ). For that same reason, we chose lectotypes for A . lhotzkianum var. hypolasium and A . sessiliflorum . In the case of A . lhotzkianum var. hypolasium , from the single gathering indicated by Malme (1927) , we elected the best-preserved material as the lectotype (S No. S04-1775) (ICN article 9.3; Turland et al. 2018 ). It is worth mentioning that unlike it was suggested by Woodson (1951) , we did not find a type specimen of A . lhotzkianum var. hypolasium in the herbarium US (S. Lutz, personal information). For A . sessiliflorum , we chose a specimen with the most informative label from the single gathering presented by Müller-Argoviensis (1860b) as the lectotype (F barcode V0092444F) (ICN article 9.3; Turland et al. 2018 ). Finally, since we did not find any extant original material belonging to the two gatherings of A . lhotzkianum cited by Müller-Argoviensis (1860a) (i.e., “ Habitat in prov. Minarum: Lhotzky in hb. Berol. ” and “ in siccis prope Cuiaba: Riedel n. 1210 ”), only the negative of Lhotzky s.n. from the herbarium B (B†, F negative No. 4420), 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 flowers from the same region that the original gathering ( Minas Gerais state ) as the neotype of A . lhotzkianum (UEC barcode UEC037427) (ICN article 9.13; Turland et al. 2018 ).
