A plant of this species was rescued from the collection made by Paul Kores at Wau by the Rev. Canon Norman Cruttwell who grew it and distributed it for general cultivation. It is a very handsome species with a large truss of golden flowers. It may be distinguished from R. zoelleri by its much more sharply attenuate leaves and finer pattern of lateral veins.
