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).
