Acalypha dikuluwensis was a 25 centimetres (9.8 in) high[2] tropical flowering plant of the genus Acalypha, belonging to the family Euphorbiaceae. The IUCN Red List of Threatened Species declared the plant extinct in 2012. A. dikuluwensis was endemic to copper-rich soils of eastern Katanga Province of the Democratic Republic of the Congo, and was only found around Dikuluwe. The soils are derived from Katanga Supergroup Upper Cambrian Roan Group rocks.[3] It was restricted to steppic savanna in copper outcrops, which were destroyed by surface mining. No specimens were found after 1959.
