The aim was to survey the floristic, structure and to characterize data of Capparis flexuosa L. in an area in the semi-arid of Paraiba State. Ninety-nine contiguous parcels of 10 m X 10 m have been established for measured standing specimens whose trunk measured ¿ 3 cm of diameter at ground level (DNS) and whose total height was ¿ 1 m. The index of diversity of Shannon-Wiener (H') and equability of Pielou (J'), density, frequency, dominance, Value of Covering (VC), Value of Importance (VI), diameter-class and height-class were calculated. It was verified that plant mean density was 2879 ind.ha-1, with 2850 individuals belonging to 22 species, 18 genera and 12 families. H' = 1.75 nats.ind-1. The value J' = 0.57 showed an ununiformity in the species distribution in the studied parcels. Capparis flexuosa was the fourth species with greatest relative density (6.04%) and relative frequence (12.43%) indicating a good distribution in the studied area; the first in relative dominance (26.03%), the third in VC (16.03%) and the fourth in VI (14.83%), suggesting that this species is well adapted to the edafoclimatic conditions of the studied area. We observed that 1.975 individuals were found between 3-6 cm of diameter and 2716 between 2.01 - 5 m height.
