Note. Robyns (1963 , p. 201) designated "For. Bur. 1901 (U)" as the lectotype of Bombax nervosum . He annotated the specimen as " Bombacopsis nervosa (Uitt.) A. Robyns, comb. nov. " and as " lectotypus !" Fernandez-Alonso (1998 , p. 310) stated that he had not seen the lectotype when he transferred Bombax nervosum to Pachira . The lectotype of B. nervosum , however, is sterile and to avoid any ambiguity about its identity, an epitype is herein selected. The epitype has flowers, a determination label in Robyns's hand, and it was cited in his revision ( Robyns 1963 , p. 201).
