Described and illustrated is Warneckea cordiformis R. D. Stone, an evidently localized endemic of coastal dry forest in Mozambique's Cabo Delgado Province. In ‘Flora Zambesiaca’ the new species would key to W. sansibarica (Taub.) Jacq.-Fél., from which it is readily distinguished by the much smaller, ovate to cordiform leaves and white, short-pedicellate flowers. Because of its evidently very limited occurrence as well as on-going anthropogenic threats, Warneckea cordiformis is here assessed as ‘Critically Endangered’ (CR) B1a,b(iii) according to IUCN criteria. A key is provided to the Mozambican species of Warneckea.
