fraseri, Menziesia pilosa, Heuchera villosa, Rhododendron catawbiense, Saxifraga michauxii, Sorbus americana, Oclemenaacuminata (= Aster acuminatus), Solidago glomerata. Other characteristic species are Minuartia groenlandica and Polypodiumappalachianum. On rock outcrops of felsic Anakeesta slate in the Great Smoky Mountains (from 1646-1987 m), typical speciesinclude Saxifraga michauxii, Carex misera, Calamagrostis cainii, Rhododendron carolinianum, Solidago glomerata, Oclemenaacuminata, Abies fraseri, and Leiophyllum buxifolium. Other characteristic species are Gentiana linearis and Calamagrostis cainii. Atlow to middle elevations (1256-1713 m) in the southern Appalachians on outcrops of mafic rock, or on felsic rock where perennialseepage exists, the sparse vegetation consists of graminoids, forbs, and shrubs. It is surrounded by deciduous forests dominated byQuercus rubra, Acer rubrum var. rubrum, and occasionally Tsuga caroliniana. Typical species here include Saxifraga michauxii,Coreopsis major, Schizachyrium scoparium, Kalmia latifolia, Dichanthelium acuminatum, Danthonia spicata, and Paronychiaargyrocoma. Other characteristic species include Campanula divaricata, Solidago bicolor, and Allium cernuum (= Alliumallegheniense). On amphibolite, metabasalt, metagabbro, or metagraywacke bedrock from 1350-1870 m elevation within a matrix ofQuercus rubra Forest or high elevation grasslands and shrublands, the vegetation includes Saxifraga michauxii, Danthonia spicata,Krigia montana, Carex misera, Angelica triquinata, Athyrium filix-femina ssp. asplenioides, Rhododendron catawbiense, andHeuchera villosa. Other characteristic species are Sanguisorba canadensis, Sibbaldiopsis tridentata, Hylotelephium telephioides (=Sedum telephioides), Houstonia purpurea var. montana, Geum radiatum, Solidago spithamaea, and Huperzia appalachiana. In thecentral Blue Ridge mountains of Virginia, at elevations of 850-1200 m, this alliance occurs on greenstone (metabasalt, a maficmetamorphic rock). Characteristic herbaceous species include Hylotelephium telephioides, Solidago simplex var. randii, Heucherapubescens, Deschampsia flexuosa, Houstonia longifolia (= Houstonia longifolia var. compacta), Dennstaedtia punctilobula,Campanula divaricata, Agrostis perennans, Carex pensylvanica, Saxifraga michauxii, Arabis lyrata, Allium allegheniense?, Phloxsubulata ssp. brittonii, Sibbaldiopsis tridentata, Liatris turgida, Huperzia appalachiana, Polypodium appalachianum, Gymnocarpiumappalachianum, and Oclemena acuminata. Shrubs include Physocarpus opulifolius, Sorbus americana, Betula alleghaniensis,Quercus rubra, Ribes rotundifolium, Diervilla lonicera, Hamamelis virginiana, Ilex montana, Kalmia latifolia, Menziesia pilosa, andAbies balsamea. Rare alpine disjunct species are sometimes present, including Juncus trifidus and Trisetum spicatum.Related Concepts:• Aster acuminatus / Menziesia pilosa outcrop community (Wiser et al. 1996) ?• Aster acuminatus / Menziesia pilosa outcrop community (Wiser 1993) ?• Calamagrostis cainii / Rhododendron carolinianum outcrop community (Wiser et al. 1996) ?• Calamagrostis cainii / Rhododendron carolinianum outcrop community (Wiser 1993) ?• Coreopsis major / Schizachyrium scoparium outcrop community (Wiser et al. 1996) ?• Coreopsis major / Schizachyrium scoparium outcrop community (Wiser 1993) ?• Deschampsia flexuosa / Angelica triquinata outcrop community (Wiser et al. 1996) ?• Deschampsia flexuosa / Angelica triquinata outcrop community (Wiser 1993) ?• Paronychia argycoma (sic) / Polypodium appalachianum outcrop community (Wiser et al. 1996) ?• Paronychia argycoma (sic) / Polypodium appalachianum outcrop community (Wiser 1993) ?• Paronychia argyrocoma - Potentilla tridentata - Arenaria groenlandica Association (Rawinski and Wieboldt 1993) ?• High Elevation Rocky Summit (Schafale and Weakley 1990) I• IE4a.
