Type.

Colombia. Vaupés, Rio Negro , San Felipe (El Castillo), below confluence of Ríos Guainía and Casiquiare , 12 Dec 1947 (lf, fr), R.E. Schultes & F. López 9342 (lectotype, designated here: GH barcode 00066501; isolectotypes: GH barcode 00066502, GH barcode 00066503) .

Note.

A single collection, "R.E. Schultes & F. López 9342," is cited in the protologue of Bombax sordidum . When Robyns (1963, p. 292) proposed a new combination and status for this name, he indicated that the holotype was deposited in the Gray Herbarium: "Colombie: Vaupes: Schultes & F. López, 9342 (f., fr., holotypus GH)". There are, however, three sheets of this collection in that herbarium, and although one was annotated as the holotype by Robyns, the ICN ( Turland et al. 2018; Art. 7.10) requires that a type designation be effectively published. The mere annotation of a herbarium sheet does not meet this requirement, hence our lectotypification (second step). We designate here the specimen that has the greatest abundance of indumentum on the abaxial surfaces of the leaflets because this character is considered diagnostic by Robyns (1963, p. 292, viz. " a specie foliolorum lamina infra densissime et sordide pulveraceo-lepidota sat differt ").
