Notes — Müller-Argoviensis (1860a) indicated the gathering Spruce 3328 in the prologue of A . verruculosum but did not cite in which herbarium the type would be deposited. Thus, we selected the best-preserved specimen as the lectotype of A . verruculosum (BR barcode 0000006960476) (ICN article 9.3; Turland et al. 2018 ). Furthermore, Azambuja (1948) indicated the gathering Ducke s.n. from the herbarium RB (RB No. 50970) in the prologue of A . paniculatum . However, since the same collection information was used for three different gatherings, corresponding to specimens with mature flowers (“ 10-4-1942 ”), flower buds (“10-3-43”), and follicles (“ 19-4-1943 ”), we chose the gathering with mature flowers as the lectotype collection of A . paniculatum (ICN article 9.3; Turland et al. 2018 ). It is worth mentioning that we consider the two preparations with this information in RB (RB barcodes 00535073 and 00567815) as a single specimen mounted on two sheets as they share a single original label, received the same voucher number, and are physically kept together (ICN article 8.3, Ex. 9; Turland et al. 2018 ). Finally, according to the lectotype label information, the numbers “918” and “1419” correspond to Ducke’s collecting numbers for the specimens with flowers and follicles, respectively. Still, none of these numbers were cited in the prologue of A . paniculatum . Regarding A . verruculosum var. laeve , Maguire & Wurdack (1961) indicated the collection Wurdack & Adderley 43280 from the herbarium NY as the holotype . Based on this information and the materials analyzed, we consider that the two herbarium sheets with this information in NY (NY barcodes 00298000 and 00298001) are duplicates, as they were identified as “ holotype ” (NY barcode 00298000) and “isotype” (NY barcode 00298001) (ICN article 8.3; Turland et al. 2018 ).
