Range of years during which specimens were collected: -

• Granite Outcrops – Granite outcrops are areas where metamorphic rock has been naturally exposed at the surface. Sometimes these are more or less confluent with the surrounding soil surfaces while sometimes they form a dome like structure (ie Stone Mountain, GA). The thin soil on the outcrop margin as well as small depressions within support a unique plant community that include many rare plant species. Granite outcrops in Alabama can be mafic or acidic which yield entirely different plant assemblages though some species can occur on both types. Mafic granite outcrops share many species with limestone glades while acidic granite outcrops are more like sandstone outcrops.--B. Keener
• Sandstone outcrop – An area where sandstone is exposed at or just above substrate level in a fashion where shallow soil pockets exist. Sandstone outcrops are very dry through much of the year, however, vernal pools may exist in the spring months. The pH is acidic.
