Plants are reclining perennial creepers. Preferred habitat is stream banks, moist places, marsh edges and ditches. Distribution is throughout the Escambia region.
Leaves are opposite on the stem; toothed margins; leaf stalks; rough; prominent upper veins; two to four inches long.
Flowers are at the end of stems; long stalks; rounded heads that stand above and apart from the leaf. Bell-shaped and numerous petals. Disc flowers are bisexual; ray flowers are sterile. Flowers occur in the spring and summer.
Fruit is achene; the outer layer is fused to the seed. However the most prolific growth comes from nodes that touch the soil and put down roots.
