CEGL004989 Saxifraga michauxii - Cheilanthes lanosa - Hylotelephium telephioides Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Michaux''s Saxifrage - Hairy Lipfern - Allegheny Stonecrop Grassland
Colloquial Name: Low-Elevation Rocky Summit (Basic Type)
Hierarchy Level: Association
Type Concept: This association is the basic equivalent of more acidic ~Saxifraga michauxii Acidic Outcrop Barrens (CEGL004524)$$ that covers examples on mafic or basic metasedimentary rocks (or felsic rocks influenced by base-rich seepage), containing plants that prefer higher pH conditions. Saxifraga michauxii is a characteristic component in stands of this and several related associations. The Basic Type is distinguished from the Acidic Type by the presence of plants such as Cheilanthes lanosa, Hylotelephium telephioides, Aquilegia canadensis, and Pycnanthemum incanum. This association is known from North Carolina and could possibly be found in South Carolina and Georgia.

Classification Comments: Formerly treated as a North Carolina state nonstandard type. North Carolina recognizes a Low Elevation Rocky Summit (Basic Subtype), a variant found on mafic or basic metasedimentary rocks or felsic rocks influenced by base-rich seepage, containing plants that prefer higher pH conditions. It was formerly provisionally classified as a state nonstandard type, ~Saxifraga michauxii - Cheilanthes lanosa - Hylotelephium telephioides Grassland (CEGL004989)$$.
