Parkia pendula (Willd.) Benth. ex Walp. is a tree species, characteristic of the initial phases of succession, of natural occurrence in Brazil. It belongs to the Mimosaceae family, with great potential in the recovery of degraded areas. The present work aims to characterize fruits and seeds morphometrically as well to identify the best temperature for use in germination test. The fruit is a type of legume, dehiscent, polispermic, with 16 seeds, approximately, per unit. The seeds present ellipsoidal format, axial embryo, with 10,1 mm of length, 4,9 mm of width and 3,1 mm of thickness. The temperatures of 25ºC and 30ºC provided them larger germinability, while the temperature of 15ºC and above 35ºC influenced these characteristics negatively.
