Notes — Müller-Argoviensis (1860a) indicated the single gathering Riedel 586 in the prologue of A. camporum but did not cite in which herbarium the type would be deposited. Thus, we chose as the lectotype of A. camporum the specimen from this collection with a readable collecting number (U barcode 0000466) (ICN article 9.3; Turland et al. 2018). Müller-Argoviensis (1860a) did the same for A. hilarianum and A. warmingii . For that reason, from the gatherings Saint-Hilaire s.n. and Warming s.n. cited in the protologues of A. hilarianum and A. warmingii , respectively, we chose the best-preserved specimens as lectotypes ( A. hilarianum , P barcode P00639562; A. warmingii , C barcode C10005753) (ICN article 9.3; Turland et al. 2018). Aspidosperma camporum was considered as a synonym of A. tomentosum Mart. & Zucc. by Woodson (1951). However, we accept A. camporum because it has petiolate leaves (0.5– 1.8 cm long) distributed along the branches, while A. tomentosum has sessile to subsessile leaves that are concentrated at the apex. Both species have a glabrous ovary, but the calyx of A. camporum is longer than A. tomentosum (4–5 vs. 2–3 mm long). Also, A. camporum is an emergent tree from the Atlantic Forest, unlike A. tomentosum , a short tree in the Cerrado. Furthermore, we observed that A. hilarianum , A. nemorale , and A. warmingii have characteristics that overlap with those mentioned above for A. camporum , in addition to present pubescent leaves with eucamptodromous venation and dark green adaxial surface. Aspidosperma camporum , A. nemorale and A. warmingii also present follicles entirely pubescent with yellowish indument (the gathering of A. hilarianum did not possess follicles). So, we consider them as synonyms of A. camporum .
