Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This association is a shrubland of the upper, dry part of the scour zone of larger streams and rivers on exposed bedrock. It is typically found on the south-facing sides of river valleys in the Ouachita Mountains ecoregion. These areas are scoured by floods that reach 5 m or more above normal summer pools. Juniperus virginiana var. virginiana and Phyllanthopsis phyllanthoides are characteristic and usually dominant. Quercus nigra and Ilex vomitoria may also be present in some examples.

Classification Comments: Compositionally related to ~Hamamelis vernalis - Cornus obliqua - Hypericum prolificum Riverscour Shrubland (CEGL003898)$$, although this occurs in different environments (on larger rivers and on higher, drier, exposed bedrock upstream of gravel/cobble bars). Known from the lower sections of the Glover River in the Ouachita Mountains. Comment in CEGL003898 refers to CEGL003942 as possibly being "a zone of this type," e.g., CEGL003898.
