摘要：

Iris hexagona occupies the borders of freshwater marshes of S Louisiana; I. fulva is found farther N along edge of natural levees, canals and swamps. Where the natural levee penetrates the marsh. natural hybridization can occur. I. fulva was more tolerant of shading I. hexagona and hybrids. I. hexagona was greatly affected by all levels of shade. -from Authors
