Note: The synonymy was proposed by Montagne (1844a: 158) and confirmed by P. Silva (1957b: 143). Montagne is usually but incorrectly cited as the combining author of the binomial Delisea elegans (C. Agardh) J. Hooker & Harvey, but in fact he was making a taxonomic statement when he wrote "Delisea elegans Lamx. (Bonnemaisonia elegans Ag.)''.
