Pursh's Peanut Grass

Amphicarpum purshii

Description: Pursh’s Peanut Grass is yet another of those popular curiosities in the Pinelands. It is indeed in the Grass Family, so it’s not closely related to the Peanut plant, but it does make something like little subterranean nutlets in addition to its above-ground florets. The scientific name comes from the Greek “Amphicarpos”—doubly fruit bearing. Frederick Pursh originally named it Milium amphicarpon (Flora Americae Septentrionalis, 1814), and his description was based on specimens from the Pine Barrens, near Egg Harbor. For a while, it was thought to be a NJ Pine Barrens endemic. It is now known from several other states on the eastern seaboard, but it is not common in any of them. It is common, however, in damp, open sandy spots in characteristic areas of the NJ Pine Barrens areas.

Duration: Annual

Flower: Early August to October.

Habitat: Moist or wet pine barrens.
