Distribution and habitat: Alcantarea acuminatifolia presents the typical habit for the genus. It grows as a rupicole on vertical granitic walls in the Atlantic Forest domain, in Minas Gerais state, about 20 km from the border with Rio de Janeiro State. It forms large and dense groups of plants completely exposed to sunlight, being quite abundant at the type locality, where it can be recognized even from a distance, due to its bulky appearance, the peculiar leaf-rosette and the well developed inflorescence. —SeeLeme & Kollmann 2013
