Pachira calophylla (K. Schum.) Fern. Alonso, Anales Jard. Bot. Madrid 56: 308. 1998.

Bombax calophyllum K. Schum., in Martius, Fl. Bras. 12(3): 227. 1886. Bombacopsis calophylla (K. Schum.) A. Robyns, Bull. Jard. Bot. État Bruxelles 33: 201. 1963.

Bombax stenopodum Ulbr., Notizbl. K. Bot. Gart. Mus. Berlin 6: 55. 1914. Type: Brazil. Rio de Janeiro, s.d. (lf, fl), L. Riedel s.n. (neotype, designated here: LE barcode 00003676; isoneotype: LE barcode 00003677; possible isoneotype: S-PLE-E4208 n.v.).

Type.

Brazil. Rio de Janeiro, s.d. (lf, fl), L. Riedel s.n. (lectotype, designated here: LE barcode 00003676; isolectotype: LE barcode 00003677; possible isolectotype: S-PLE-E4208 n.v.) .

Note.

Robyns (1963, p. 203) designated "Riedel s.n. (LE)" as lectotype of Bombax calophyllum . When Fernández-Alonso (1998) made the combination in Pachira , he accepted Robyn’s type designation, but stated that he had not seen the lectotype. Robyns annotated the two Riedel specimens in St. Petersburg (LE) cited above as " Bombacopsis calophylla (K. Schum.) A. Robyns, comb. nov. " and wrote " lectotypus " on the one specimen that has a handwritten label indicating the type locality as " Brasiliae: R. Janeiro," locality information that matches the protologue. 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 the type to a single element, a gathering that has loose leaves and a fragmented flower (calyx, ovary, and androecium). The isolectotype is sterile.

The protologue of Bombax stenopodum cites a single collection, "E. Ule n. 4631," which was deposited in Berlin (B†; see F neg. no. 9545). Inasmuch as the Berlin specimen was destroyed in WWII and no duplicate material has been found, we designate a neotype for this name. Our choice makes this name an obligate synonym of Pachira calophylla .
