Scleria aurantiaca Lye is described from eastern Gabon. It is superficially similar to S. nyassensis , but probably more closely related to S. adpresso‐hirta , which has a more similar nutlet and hypogynium. The scientific name is derived from the bright orange ring of the hypogynium. The fruit of S. aurantiaca has both micro‐ and nano‐papillae, which are described here for the first time. Also discussed is the water transport through surface hairs to the embryo in the fruit. Due to the restricted range of this species, it must be considered as ‘Endangered’ (EN).
