B†, F negative No. 4414 image!. “ Aspidosperma guarantiacum ” Malme , orth. var. Notes —The diagnosis of A . pyrifolium presented in “ Flora ” by Martius & Zuccarini (1824) was based on a single collection made by Martius himself, though the indication of the original material ( Martius s.n. ) was only made later by Martius (1824) in “ Nova Genera et Species Plantarum ”. Since this name was published without a holotype , we selected a specimen with the best-preserved inflorescences from the original material as the lectotype of A . pyrifolium (M barcode M-0184040) (ICN article 9.3; Turland et al. 2018 ). Lastly, after analyzing the isolectotypes of A . pyrifolium , we observed that one specimen belongs to A . multiflorum A.DC. (M barcode M-0184041), so we are excluding it from the collection of A . pyrifolium . Martius (1838) cited the gathering “Silva Manso” ( Silva Manso 136 ) (“ Herb. Mart. Fl. Bras. No. 485 ”) in the protologue of A . martii but did not cite in which herbarium the type would be deposited. Since there are several sheets of Silva Manso 136 , we selected as the lectotype the specimen with the most informative label (BR barcode 0000006960001) (ICN article 9.3; Turland et al. 2018 ). Martius (1838) did the same for A . molle , and from the gathering Martius s.n. , we selected the best-preserved specimen as the lectotype (M barcode M-0184043) (ICN article 9.3; Turland et al. 2018 ). Regarding A . guaraniticum , Malme (1899) mentioned two gatherings in its protologue, of which Woodson (1951) cited Malme 1006 as the type without indicating the herbarium. Thus, we chose as the secondstep lectotype a material with the most informative label (S No. S04-1754). In the protologue of A. populifolium , de Candolle (1844) indicated a specimen of Gardner 2664 from the personal herbarium of Boissier as the type (“ v. in h. Boiss. ”). Since only one sheet of this gathering possesses the “Herbier Boissier” label, we consider it as the holotype of A. populifolium . Finally, according to Gardner’s “Catalogue of Brazilian Plants” ( Hind 2012 ), the collection of A . populifolium was made in 1839. The only herbarium sheet with the correct collection date is the one from the herbarium K (K barcode K000587645).
