Agalinis obtusifolia, commonly known as Tenlobe false foxglove, is an annual plant native to the southeast region of the United States of America. ^{[1] [2]} It is considered to be parasitic to the roots of herbaceous species. ^[2]

Description

A. obtusifolia is light yellow to green in color. The stems are slender and stiff, and may reach a height between 30 and 90 centimeters (11.81 to 35.43 inches). The leaves are filiform and oppositely arranged, reaching a length of 5 to 15 millimeters. The flowers possess five petals, which tend to be pink, purple, or (rarely) white in color. ^[2]

Distribution and habitat

This species can be found across the United States' Coastal Plain region, its range stretching from Delaware to Florida and westward to Louisiana. ^[3] There exist some disjunct populations within the states of Tennessee and Kentucky. ^[4]

A. obtusifolia has been observed to occur in habitat types including upland pine communities, peaty areas, flatwoods, and savannas, among other types. ^[5]
