This species has a disjunct distribution; it occurs in Savanna and Tropical Dry Forests. Conservation Status: Near Threatened (NT). Zornia leptophylla has a relatively wide distribution. However, the disjunct distribution contributes to the vulnerability of the species (EOO= 3,342,561.976 km ²; AOO= 220.000 km ²).
