What is "robynsia"

Robynsia is a monotypic genus of flowering plants in the Rubiaceae family. It was described by John Hutchinson and was named after his friend and colleague Walter Robyns. The genus contains only one species, i.e. Robynsia glabrata, which is found in Ghana, Ivory Coast and Nigeria. The species is morphologically similar to the genus Cuviera but differs by having long, slender corolla tubes.
