Micranthocereus violaciflorus is found at three locations in Minas Gerais, Brazil, where its total extent of occurrence is around 2,500 km2. The quality and extent of its habitat are being affected by deforestation for Eucalyptus plantations and fires, which already have led to population declines. Hence, M. violaciflorus is listed as Endangered under criterion B.
Previously published Red List assessments:
