Hyperacanthus (plant)


Hyperacanthus is a flowering plant genus in the family Rubiaceae, occurring on Madagascar and nearby southern Africa, approximately from Mozambique to the southernmost parts of the continent.
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.DavisHyperacanthus amoenus BridsonHyperacanthus exosolenius Hyperacanthus grevei Rakotonas. & A.P.DavisHyperacanthus lantzianus Hyperacanthus lastellianus Hyperacanthus madagascariensis Rakotonas. & A.P.Davis Hyperacanthus mandenensis Rakotonas. & A.P.DavisHyperacanthus microphyllus BridsonHyperacanthus perrieri Rakotonas. & A.P.Davis Hyperacanthus pervillei Rakotonas. & A.P.Davis Hyperacanthus poivrei Rakotonas. & A.P.Davis Hyperacanthus ravinensis Rakotonas. & A.P.Davis Hyperacanthus talangninia Rakotonas. & A.P.Davis
