Diagnostic Characteristics:
This is a very diminuitive plant with narrow linear leaves less than 3 mm wide and 6 times longer. The leaves have only a midrib evident (not lateral veins) and the upper ones are much smaller than the lower ones. The plants are glabrous (without hairs). Species in this genera have petals and they are longer than the 5 sepals. The sepals are obtuse (blunt and the sides at the tip are more than 90 degree angle apart) and they do not have prominent veins. There 3 or more flowers on a plant and they often emerge from below the middle of the stem. It is found on open rocky ground, sandstone cliff and glades.

The habitat for this species is especially sensitive to changes in hydrology and not likely to withstand much alteration. Grazing or browsing pressure, vegetation removal, hydrologic changes (i.e. stream alterations road construction) would be detrimental. Exotic pest plants are a threat to this species and should be removed. Avoid creating access to the site through trail or road construction.

Global Range:
Most common in the mountains of Georgia, Tennessee, and North Carolina. Also locally distributed north on granitic or siliceous rock of the Shawangunk and Catskill Mountains of New York, wooded ledges in Connecticut and Rhode Island, hills of New Hampshire and Maine, and along the coast in Maine.
