Amphicarpum amphicarpon, commonly known as peanut grass or Pursh's blue maidencane, is an annual wetland species found in the eastern United States. Its common name honours botanist Frederick Traugott Pursh.[2] It was previously considered to be part of the genus Milium.[3]
Distribution
It is found along the coastal areas from New Jersey to Georgia.[2] It was previously found within New York state but is now considered possibly extirpated.[3] A single population was discovered on Nantucket in 1988, 240 miles north of its previously known northernmost site.[4]
Description
Amphicarpum amphicarpon grows 1 to 2 feet (0.30 to 0.61 m) tall. Its stems and leaves are bristly and hairy; the leaves ascend.[5]
The plant produces subterranean fruits early in the growing season, which are self-fertilizing (cleistogamous).[4][6] Later, it produces aerial fruits.[2] It flowers and fruits between August and October.[5]
