Wild buckwheat
 

Wild buckwheat resembles morningglories in its heart-shaped, alternate leaves. A member of the Polygonaceae (smartweed) family, wild buckwheat has ocreas at the base of leaf petioles while morningglories do not.

The plant may also be confused with bindweeds because of the basal lobes on the leaves. However, wild buckwheat's lobes point inward while those of bindweeds are directed outward. Wild buckwheat lacks hairs on its stems and leaves. Because of their greenish white color, flowers are not very noticeable.

Scattered throughout Missouri, wild buckwheat is a weed of landscapes and agronomic crops.
