|Echium vulcanorum in Chã das Caldeiras.|
Common names[change | change source]
It is locally known as lingua de vaca ("tongue of cow") because their leaves are rough. The same name is used for the other species of Echium that are found in Cape Verde: Echium hypertropicum and Echium stenosiphon.
Description[change | change source]
Where it grows[change | change source]
Echium vulcanorum is endemic of the Cape Verdean island of Fogo on the volcano Pico do Fogo. It occurs on volcanic soils of Fogo Island, mainly as two populations at Monte Losna/Pico Novo, where they can be found at about 1700 m, and in the border of the crater of the Pico do Fogo (the Bordeira region ) at altitudes between 2200 and 2400 m. A small population was also reported in Chã das Caldeiras (±1600 m). These populations exist generally in places facing to the southwest or the southeast. It prefers soils with a recent volcanic origin.
Conservation[change | change source]
Echium vulcanorum is used for the production of firewood (dry wood that will be burned) and destroyed by goats, so this species, as well as the other two Echium species of Cape Verde, is seriously threatened, so that measures for its protection should be taken with urgency.
