Alcantarea galactea

A large tank bromeliad from the granite inselbergs of Espírito Santo, south-east Brazil, where it sits on bare sunlit rock. Little is published on this species itself, so these conditions come from the measured site climate and what is known for rock-dwelling Alcantarea: strong sun, warm days, a drier winter and a fast-draining footing.

Where it grows wild

Like most Alcantarea it is expected to grow on exposed granite and gneiss outcrops (inselbergs) in the Atlantic Forest region, rooted in thin mats or rock cracks with water held in the leaf tank.

Few records carry an elevation; the one climate site sits at about 310 m in lowland to submontane Espírito Santo.
