HERB LAYER SPECIES OF AN ULTRAMAFIC OUTCROP BARREN

Occur on outcrops of dunite, serpentine or related ultramaphic rock, usually on southern or flat exposure.
Very rare community, one in mountains of North Carolina, one near Augusta, Georgia. (Schafale and Weakley 115,116)

HERB LAYER SPECIES OF A MESIC PINE FLATWOODS

This Coastal Plain community has similarities to former Piedmont Longleaf Pine Forest (Schafale and Weakley 80) once possibly extensive in lower Piedmont, but now gone due mainly to fire supression. (Schafale and Weakley 131-133)
