Flowering & fruiting: Flowering from May to July; fruiting in July.

Distribution: Distributed disjointly in Panama and Brazil, it is recorded in Bahia, Paraíba, Sergipe ( Wood et al., 2020) and Ceará. It grows in Caatinga areas ( Simão-Bianchini et al., 2024), particularly in Dry Forests and “Brejos de Altitude” ( Wood et al., 2017b). In Paraiba, it is rare, with only two populations found in the IRs of Campina Grande and João Pessoa in Atlantic Forest or in transition areas to Caatinga.
