- Dyckia horridula was originally collected in 1894 by Auguste Glaziou, and besides the types specimens there are very few representatives in herbaria. The taxon was recently rediscovered in the vicinity of type locality, in the periphery of the city of Santo Antonio do Descoberto. It is a typical inhabitant of the Campos Rupestres in the domain of the Cerrado vegetation, where the individuals grow sparsely distributed in rocky soils and due to its small size are hidden by the herbaceous vegetation even when in bloom, which makes the task of locating the specimens in habitat difficult.
The future of D. horridula in its original habitat, at least around the city of Santo Antonio do Descoberto, is uncertain due to urban expansion and the consequent degradation of the surrounding Campos Rupestres and Cerrados. It is also severely affected by frequent fires and cattle breeding activities —SeeJ. Bromeliad Soc.
