Aspidosperma formosanum Duarte in Arq. Jard. Bot. Rio de Janeiro 19: 218. 1973.

Holotype:— BRAZIL. Goiás: Formosa para Poções, 19 Oct 1965, A.P. Duarte 9387 (RB (mounted on three herbarium sheets) [barcode 00535041!, barcode 00567817!, barcode 00567818!]; isotypes: CEN [barcode CEN00071899 image!], NY [barcode 01546547 image!]) .

Notes — Duarte (1973) indicated the gathering Duarte 9387 from the herbarium RB in the protologue of A. formosanum . Based on this information and the materials analyzed, we consider that the three herbarium sheets with this information in RB (RB barcodes 00535041, 00567817, and 00567818) belong to a single specimen mounted on three 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).
