Notes

Flowers July to August

Wetland indicator: OBL

This species is usually found growing in peat and/or sand at or just below the water level and is likely to be overlooked except when it is in flower. The flowers are quite impressive for such a small plant. When blooming plants are found the small leaves can often be found by searching the surface of the soil and below these in the substrate are the tiny bladders. It often occurs near rivulets running through poor or medium fens in the Adirondacks and in the New Jersey Pine Barrens, presumably in similar habitats elsewhere.
