Poinciana bijuga Linnaeus, Species Plantarum, ed. 2, 1: 544. 1762, nom. illeg.
"Habitat in Indiis." RCN: 2990.
Replaced synonym: Poinciana bijugata Jacq. (1760) .
Type not designated.
Current name: Caesalpinia vesicaria L. ( Fabaceae: Caesalpinioideae).
Note: This is evidently an illegitimate renaming of Poinciana bijugata Jacq. (1760), or possibly an orthographic variant of it. In either case, the name is homotypic with that of Jacquin.
