Asplenium montanum Central Appalachian Sandstone Cliff Sparse Vegetation
Translated Name: Mountain Spleenwort Central Appalachian Sandstone Sparse Vegetation
Common Name: Central Appalachian Spleenwort Acidic Cliff
Unique Identifier: CEGL004391
Classification Approach: International Vegetation Classification (IVC)
Summary: This type includes acidic cliffs with sparse vegetation. It is typically scattered on quartzite and sandstone cliffs in the Central Appalachians, with a few disjunct occurrences on river bluffs, foothills and monadnocks of the western Piedmont in Virginia and Maryland. Vegetation is characterized by species such as Asplenium montanum, Deschampsia flexuosa, Polypodium appalachianum, and Polypodium virginianum (= Polypodium vulgare).
