Examined material:— BRAZIL. Paraíba: Maturéia, Pico do Jabre , 900 m elev., 13 May 2019, fl., Aureliana Gomes 2096 ( HACAM) .
Distribution and ecology:— The species has distribution in South America, among secondary vegetation ( Lima & Mansano2011).In Brazil, it is present in the Central-West,Northeast, Southeast and South regions in the phytogeographic domains of Caatinga, Cerrado, Atlantic Rainforest and Pantanal, in rocky fields, seasonal semideciduous forest, rain forest and in sandbank areas (INCT - Virtual Herbarium of Flora and Fungi). This species occurs preferably in the undergrowth of the forest ( Queiroz 2021).
Phenology:— Found with flowers in May.
