Agarista oleifolia is distributed in Eastern Brazil, ranging from the states of Bahia to Paraná, and in the central region of the country, in the states of Goiás and Mato Grosso. It inhabits environments characterized by rocky outcrops and watercourse margins. The species undergoes flowering from September to November and fruiting from October to June.

Judd (1983) and Romão et al. (2024) recognized two varieties for this species, primarily distinguished by the trichomes on the inflorescence rachis present in A. oleifolia var. oleifolia and absent in A. oleifolia var. glabra (Meissn.) Judd. Only the typical variety occurs in the study areas, specifically in the Serra de São José, where the species A. eucalyptoides is also found, slightly resembling A. oleifolia but easily distinguished by its leaves with slender and flexuous petioles, unlike A. oleifolia, which has more robust and nonflexuous petioles.
