Euphorbia stygiana
Euphorbia stygiana (Portuguese: Trovisco-macho) is a species of evergreen shrub in the family Euphorbiaceae, endemic to several islands of the Azores. It has a critically endangered subspecies (subsp. santamariae) with only 20 known remaining mature individuals in the wild.
Like other members of the Euphorbia genus, E. stygiana has a milky white sap that may cause skin irritation or allergic reaction when in contact with the skin or eye. It is toxic if eaten.
Euphorbia stygiana is endemic to all Azorean islands except Graciosa where it inhabits the extremely humid highlands of the archipelago from 300 to 1,100 metres (980 to 3,610 ft) in altitude, especially on Pico Island, in sheltered places such as ravines, craters and dense laurel-Juniperus forests.
