CEGL004347 Sedum pulchellum - Phemeranthus calycinus - Oenothera linifolia Shale Glade Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Widow''s-cross - Rockpink Fameflower - Threadleaf Evening-primrose Shale Glade Vegetation
Colloquial Name: Interior Highlands Shale Glade
Hierarchy Level: Association
Type Concept: This association is found in the Ouachita Mountains of eastern Oklahoma and western Arkansas on flat to gently sloping, south-facing shale outcrops with patches of forb-dominated vegetation and scattered woody species. The nominal species are Sedum pulchellum, Phemeranthus calycinus, and Oenothera linifolia. Other associated species include Croton michauxii var. ellipticus, Plantago aristata, Coreopsis lanceolata, Agrostis elliottiana, Danthonia spicata, Hordeum pusillum, and Ruellia humilis. Woody species include Smilax bona-nox, Ulmus alata, Juniperus virginiana, Pinus echinata, and Vaccinium arboreum. Vernal pools are important for some species.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Nominal species are needed to distinguish this type from Tennessee limestone glades. Known from Irons Fork River corridor in the Ouachita Mountains of Arkansas. Occurrences are degraded by vehicular traffic and other human disturbances. Another example may include the Mazarn Shale Glades (check with T. Foti for report by Bridges and Orzell). In eastern and east-central Oklahoma associated species include Aristida oligantha, Bouteloua hirsuta, Chaetopappa asteroides, Croton monanthogynus, Diodia teres, and Vulpia octoflora var. octoflora (= Festuca octoflora) (Hoagland 1998b).
