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 .
