New Jersey Goober-grass Amphicarpum amphicarpon

Pursh's blue maidencane is an annual grass in the Poaceae (grass) family.  It was named after botanist Frederick Pursh in 1950. 

Its growth habit is quite similar to peanuts, with the plant producing subterranean fruits early in the growing season and aerial fruits later in the growing season.  Both types of fruits are fertile.  

It is found in sandy pine forests, wet pine savannas, wetlands, ponded locations, and small bays along the shores and rivers of the eastern United States from New Jersey to Georgia.  It is typically found in locations where sphagnum moss grows.  Trampling along the shoreline by ATV's and foot traffic, and the presence of overgrowth are considered threats to the survival of this plant.  In North Carolina, it can be found in numerous coastal counties, however, it is considered as a Watch List species.  

Its flowers occur in scaly structures called spikelets and are raised above the leaves on narrow, erect branches.  They appear in the form of a panicle, with lengths of 8".  Its leaves, sheaths and blades are all pubescent.  The lower blades can reach heights of up to 30", with a width of one-half inch.  The upper leaves are narrower.
