Seven genera and fourteen native species were found in the researched area, as well as five genera and five species cultivated or subespontaneus. Related to native plants, the genus Cayaponia Silva Manso presented a greater number os species (5), followed by Melothria L. (3) and Psiguria Neck ex Arn.
