Variation

Euphorbia tuckeyana on the crater rim of Chã de Caldeiras on Fogo Island

Old plants higher than 0.5–1 m are extremely rare today. Large plants up to 2 m are only known from outer escarpments of the central caldeira on Fogo as scattered relicts of a scrub vegetation type.

Distribution and ecology

Artemisia gorgonum are found in much of the Cape Verde islands with the exception of the eastern islands of Boa Vista and Maio. It is mainly occurring in the subhumid and humid zones, but it has also been reported from the arid zone on Santiago. The uppermost records are from the caldeira rim on Fogo up to 1800 m (leg. Killian & Leyens). The main altitudinal distribution is between 200 m and 1,600 m. The plants grow on rocky soil particularly on mountain slopes and less frequently in steep cliffs and they form a characteristic, but not dominating element of the indigenous montane scrub vegetation in the Cape Verde Islands.

Other

Euphorbia tuckeyana was issued on a Cape Verdean stamp in 2002.^[2]

Euphorbia tuckeyana can be founded at Jardim Botânico Nacional Grandvaux Barbosa in São Jorge dos Órgãos in eastern Santiago Island.
