Examined material:— BRAZIL. Paraíba: Maturéia, Pico do Jabre , 875 m elev., 13 October 2019, fl. & fr., Aureliana Gomes 2022 ( HACAM) .

Distribution and ecology:— The species has a wide distribution in South America. In Brazil, it occurs in all regions, being widely distributed in the Northeast (BA, CE, PE, PI, RN) associated with the Amazon, Caatinga, Cerrado and Atlantic Rainforest domains, found in rocky outcrops vegetation, and seasonal forests, as well as anthropized areas ( Flora do Brasil 2020).

Phenology:— Registered with flowers and fruits in October.

Taxonomic discussion:— Mimosa invisa can be recognized, mainly, by the shrub habit, glabrous branches, with rickly., inflorescence pink spikes and long craspedium with straight margin. This was the only representative of Mimosa with a vine habit, a characteristic that differs from the other similar species found in the study area, which show arboreous habit.
