Pitted Morningglory

Weed Flora of Mississippi

Prepared by

Taghi Bararpour and Jason Bond

Family: Convolvulaceae (morningglory family)

Genus: Ipomoea       Species:   lacunosa

History: Thought to be native to tropical or subtropical North America.

Life Cycle: Summer annual

Special Characteristics: The Convolvulaceae family is a large group, with more than 59 genera and 1,800 species of mostly trailing and climbing vines and a few shrubs and small trees. There are more than 500 species of Ipomoea. The deeply indented cotyledons, heart-shaped leaves that taper to a point, and relatively small white flowers are all characteristics that help in the identification of pitted morningglory.

Roots: Fibrous

Stems: Sometimes slightly hairy, trailing along the ground or climbing.

Leaves: Relatively long petioles and are arranged alternately along the stem. Leaves can be without hairs or only slightly hairy

Flower: Funnel-shaped, white in color

Seeds / Fruit: A capsule

Seedling: Cotyledons are deeply indented and taper to a point as compared to tall, ivyleaf, and entireleaf morningglories.

Interference: Pitted morningglory can compete severely with crops and is capable of reducing crop yield up to 81% by increasing crop lodging and reducing the efficiency of crop harvesting. Full-season interference of annual morningglories increases lodging, reduces efficiency of mechanical harvest, and reduces soybean yield up to 75%.
