Status

The species appears to have been frequently collected from about 1902-1937 within a 60 km radius of the District of Columbia. All of these collections were made from areas that are currently heavily urbanized and all are presumed extirpated. The decline in Maryland populations is mirrored by a widespread regional decline. The late F. W. Pennell, a noted Agalinis expert, made several collections of A. obtusifolia from the District of Columbia and from Prince George’s County in the early 1900s. Despite the taxonomic confusion, A. obtusifolia is firmly established as a historical component of the Maryland flora (MD DNR).

Where To Find

Sandy barrens and woodland glades (MD DNR).

Agalinis obtusifolia

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

[edit]

Agalinis 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

[edit]

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]

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