Rhigospira is a genus of flowering plants in the family Apocynaceae, first described as a genus in 1878 by John Miers.[2] The species, Rhigospira quadrangularis was first described as Ambelania quadrangularis by Johannes Müller Argoviensis in 1860[3] but was transferred to the genus, Rhigospira, in 1878 by John Miers.[4] The genus contains only one known species, Rhigospira quadrangularis, native to northwestern South America (Colombia, Venezuela, Peru, NW Brazil ).[5][6]
