Mud Plantain - Kidney Leaf Mud Plantain
Heteranthera reniformis -
Ruiz & Pavon
Pontederiaceae (Pickerelweed) Family

Plant is a small aquatic, usually no more than 8 to 10 inches tall; smooth, annual or perennial. Its preferred habitat is any location with standing water or grounds that are moist throughout the year. The root system creeps along the mud, rooting at the nodes. The stems are wrapped by thick squamiform sheaths. Distribution is occasional in the Escambia region.

Flowers are a 2 to 10 flowered raceme. Each flower has 6 tepals that are united at the base, forming a tube. The color is white to pale blue. The tepals are lance-like, sharply pointed. The two outer tepals usually bend in towards the tube and the third bends outward. There will be 3 stamens; 2 small with a yellow anther and the third longer with a grey-blue anther.

Fruit is a capsule with many seeds.

The leaves are alternate on the stem, smooth; the blade being less than 2 inches in length or width; cordate or reniform in shape. The tip is obtuse or rounded at the apex and bilobate at the base. The leaf stalk is usually 4 to 7 inches long.

Identification can be misleading as the plant is often confused with Heteranthera limosa.
