Hyperacanthus amoenus

This genus used to contain only 5 species, but the number has tripled since a number of plants formerly believed to be genip-trees – the "Genipa sensu Drake" group – were recognized to be not as closely related to genips as was previously believed. Those species are now placed in Hyperacanthus, at least provisionally:

• Hyperacanthus ambovombensis Rakotonas. & A.P.Davis
• Hyperacanthus amoenus (Sims) Bridson
• Hyperacanthus exosolenius (formerly in Genipa, tentatively placed here)
• Hyperacanthus grevei Rakotonas. & A.P.Davis
• Hyperacanthus lantzianus (formerly in Genipa, tentatively placed here)
• Hyperacanthus lastellianus (formerly in Genipa, tentatively placed here)
• Hyperacanthus madagascariensis (Lam.) Rakotonas. & A.P.Davis (formerly in Genipa)
• Hyperacanthus mandenensis Rakotonas. & A.P.Davis
• Hyperacanthus microphyllus (K.Schum.) Bridson
• Hyperacanthus perrieri (Drake) Rakotonas. & A.P.Davis (formerly in Genipa)
• Hyperacanthus pervillei (Drake) Rakotonas. & A.P.Davis (formerly in Genipa)
• Hyperacanthus poivrei (Drake) Rakotonas. & A.P.Davis (formerly in Genipa)
• Hyperacanthus ravinensis (Baill. ex Drake) Rakotonas. & A.P.Davis (formerly in Genipa)
• Hyperacanthus talangninia (DC.) Rakotonas. & A.P.Davis (formerly in Genipa)
• Hyperacanthus tubulosus (formerly in Genipa, tentatively placed here)
