Leaves: Alternate, lance-shaped to narrowly elliptic with very short petioles and smooth margins. Stems reddish, angled, and slightly winged.

COMMON CONFUSIONS:

Other erect-growing North Carolina Ludwigia species tend to have more than four petals or none at all. The similar Ludwigia decurrens (wing-leaf primrose-willow) has winged stems, the wings originating from the base of each leaf and extending down the stem. Ludwigia decurrens also has elongated, winged fruits.
