Notes — Azambuja (1946) indicated the gathering Ducke 931 from the herbarium RB (RB No. 50969) in the prologue of A. obscurinervium . However, since the same collecting number was used for two different gatherings, corresponding to specimens with flowers (“ 16-5-1942 ”) and follicles (“XI-42”), we chose the gathering with flowers as the lectotype collection of A. obscurinervium (ICN article 9.3; Turland et al. 2018). It is worth mentioning that we consider the four preparations with this information in RB (RB barcodes 00535070, 00535154, 00535155, and 00535156) as a single specimen mounted on four sheets since they possess a single original label in common, received the same voucher number, and are physically kept together (ICN article 8.3, Ex. 9; Turland et al. 2018).
