An orchid of dry chestnut oak forests with shallow soil and exposed bedrock, and pitch pine scrub oak barrens on sandy soils (New York Natural Heritage Program 2004). Dry, open woods, shale barrens and sandy pine barrens (Flora of North America 2002). Dry sandy woods and adjacent clearings; very dry, open woods on hilltops and on steep, dry shale barrens (Catling 1991). Dry sandy woods and clearings (Fernald 1970).

Chestnut oak forest A hardwood forest that occurs on well-drained sites in glaciated portions of the Appalachians, and on the coastal plain. This forest is similar to the Allegheny oak forest; it is distinguished by fewer canopy dominants and a less diverse shrublayer and groundlayer flora. Dominant trees are typically chestnut oak and red oak. Pitch pine-heath barrens* A shrub-savanna community that occurs on well-drained, sandy or rocky soils. The most abundant tree is pitch pine and the shrublayer is dominated by heath shrubs. * probable association but not confirmed Pitch pine-oak-heath rocky summit* A community that occurs on warm, dry, rocky ridgetops and summits where the bedrock is non-calcareous (such as quartzite, sandstone, or schist), and the soils are more or less acidic. This community is broadly defined and includes examples that may lack pines and are dominated by scrub oak and/or heath shrubs apparently related to fire regime. * probable association but not confirmed

Pitch pine-scrub oak barrens A shrub-savanna community that occurs on well-drained, sandy soils that have developed on sand dunes, glacial till, and outwash plains. Red cedar rocky summit* A community that occurs on warm, dry, rocky ridgetops and summits where the bedrock is calcareous (such as limestone or dolomite, but also marble, amphibolite, and calcsilicate rock), and the soils are more or less calcareous. The vegetation may be sparse or patchy, with numerous lichen covered rock outcrops. * probable association but not confirmed
