Notes —Among the nine gatherings mentioned in the protologue of A. woodsonianum, Markgraf (1935a) proclaimed Boschwezen [Forestry Department] 2330 as “Original der Art.”. Still, he did not cite in which herbarium the type would be deposited. So, we selected the best-preserved specimen from this collection as the lectotype of A. woodsonianum (U barcode 0000489) (ICN article 9.3; Turland et al. 2018).

Woodson (1951) accepted A. album but synonymized A. centrale Markgr. , A. desmanthum Benth. ex Müll. Arg. , and A. pachypterum Müll.Arg. under it. However, we consider these as distinct species. Aspidosperma album differs from A. centrale by the dark green leaves on the adaxial surface (vs. dark brown), with prominent secondary veins (vs. immersed), smaller (5.7–6.5 vs. 9.2–11.7 cm long) and non-rigid (vs. rigid) inflorescences, and flowers with corolla tube pubescent to glabrescent below the insertion of the anthers internally (vs. canescent) ( Pereira et al. 2019). Moreover, A. album differs from A. desmanthum by the prominent secondary veins on the adaxial surface (vs. immersed), white leaves on the abaxial surface (vs. light green), and flowers ca. 6.6 mm long (vs. ca. 8 mm). Finally, A. album can be differentiated from A. pachypterum by the white leaves on the abaxial surface (vs. light brown or light green), suborbicular follicles (vs. pyriform), and membranaceous seeds (vs. chartaceous).
