- Alcantarea nigripetala was found growing on inclined granitic rock surfaces along the road from Santa Luzia do Córrego Azul, a district of the County of Água Doce do Norte (Espírito Santo), to Nova Belém (Minas Gerais), very close to the states border, where it forms a sparse population already affected by the surrounding pastureland activities, which isolated the studied population and makes it more vulnerable to fire episodes. Some of the outstanding botanical elements observed in the same area are (Orchidaceae), Mandevilla fistulosa M. Sales, Kin.-Gouv. & A. O. Simões (Apocynaceae) and the columnar Cactaceae Coleocephalocereus buxbaumianus Buining. —SeeJ. Bromeliad Soc.
