Bombax retusum Mart., Flora 8: 28. 1825, Ibid., Nov. Gen. Sp. Pl. 1(4): 92-93, t. 59. 1826 [1824]. Bombacopsis retusa (Mart.) A. Robyns, Bull. Jard. Bot. État Bruxelles 33: 205. 1963.

Type.

Brazil. Minas Gerais, In deserto Serro Frio, [1817-20] (fl), C.F.P. von Martius s.n. (lectotype, designated here: M barcode 0211681; isolectotype: M barcode 0211682; possible isolectotype: S-PLE-E4218 n.v.) .

Note.

When Robyns (1963, p. 207) stated that a Martius specimen in Munich (M) was the " holotypus " of the name Bombax retusum , he effectively selected a lectotype ( Turland et al. 2018; Art. 9.10). However, there are at least two specimens with identical label data in that herbarium that must be considered syntypes as well as a copy of the plate cited in the protologue ("tab. 60," sphalm. pro 59), but published a year later (Martius 1826). Robyns wrote " holotypus " on one of the two specimens and annotated all three elements as " Bombacopsis retusa (Mart. et Zucc.) A. Robyns, comb. nov. " The ICN ( Turland et al. 2018; Art. 7.10) requires that a type designation be effectively published and the mere annotation of a herbarium sheet does not meet this requirement. Our lectotypification (second step; see Turland et al. 2018; Art. 9.17) narrows Robyns’ selection to the specimen with the best flowering material.

Robyns (1963, p. 205) attributed the basionym to "Mart. et Zucc.," but according to Stafleu and Cowan (1981, p. 329) authorship is to be attributed to von Martius alone. Fernández-Alonso (2003, p. 36) also included J.G. Zuccarini as a co-author of this species name. Interestingly, Schumann (1886, p. 226) recognized " Bombax retusum Mart." while citing " Bombax retusum Mart. et Zucc.! Nov. gen. et spec. I. 92. t. 59." The article that includes the validating description of B. retusum (Martius 1825) clearly states that Martius collected and described ("collegit et descriptsit") the plants while Zuccarini organized the plates, etc. (" Pingendas curavit et secundum auctoris schedulas digessit ").
