Common in salt marshes all along the coast and rarely in 

 sandy swamps in the Pine Barrens. None of the lists refer to 

 this species as occurring away from the coast, although specimens 

 collected by Cooper at Oualcer Bridge have long been in the 

 Academy herbarium ; they and other Pine Barren material show 

 no difference whatever from the maritime plant. '*'
