Type.

Brazil. Pará, Itaituba, Rio Tapajoz, 26 Aug 1923 (lf, fl), A. Ducke s.n. [RB 18094] (lectotype, designated here: RB barcode 00534489; isolectotypes: B† [= F neg. no. 9540], G barcode 00177452, K barcode 000382352, RB barcode 00534497 [without original label], S-R-11283, U barcode 0008391, U barcode 0008392, US barcode 00101944).

Note.

Three syntypes are cited in the protologue. Robyns (1963) selected one, "Ducke 18094," as the lectotype (first step) of Bombax paraense and stated that it was deposited in RB. There are, however, two sheets in RB of this collection. Our lectotypification (second step) narrows Robyns’s choice to a single specimen and it is the same one he annotated as " lectotypus."
