Examined material:— BRAZIL. Paraíba: Maturéia, Pico do Jabre , 1.100 m elev., 23 August 2019, fl., Aureliana Gomes 3174 ( HACAM) .
Distribution and ecology:— The species is distributed from southern Mexico to northern Argentina. In Brazil, it is associated with the Central-West (DF, GO, MS, MT), Northeast (BA, CE, PB), Southeast (ES, MG, RJ, SP) and South (PR) regions in the Cerrado and Atlantic Rainforest domains in deciduous seasonal vegetation, semideciduous seasonal forest and ombrophilous forest ( Mathias et al. 2000; Flora do Brasil 2020). Recently this species was found in Cariri Paraibando in dry forest net the granitic formations ( Queiroz 2021)
Phenology:— Registered with flowers in August.
Taxonomic discussion:— Myroxylon peruiferum can be recognized, mainly, by the arboreous habit, imparipinnate leaves with alternate leaflets, white flowers and samara type fruit. Among the species with imparipinnate leaves and alternate leaflets in the studied area, it is the only one that presents leaflets with pellucid glands.
