Floristic composition and potential competitors in Lindera melissifolia (Lauraceae) colonies in Mississippi with reference to hydrologic regime
Lindera melissifolia is a federally endangered shrub endemic to the southeastern United States. Hydrologic regime and floristic composition within individual L. melissifolia colonies in three disjunct populations in Mississippi were monitored for three years. Sixty-nine vascular plant species were identified growing within L. melissifolia colonies. Although number of flooding events and flood duration varied among the three populations, floristic composition and the ratio of L. melissifolia to other plants in the colonies remained relatively constant during the study period. In Mississippi, Smilax spp. and Vitis spp. have the greatest potential to become strong competitors of L. melissifolia.
