Description
A. virgata is a perennial graminoid of the Poaceae family native to North America. [1] It is a tufted perennial reaching up to 1 m tall, with glabrous sheaths that can be longer or shorter than the internodes. Leaf blades flat to curling, panicles narrow with loosely to densely arranged flowers. Central awn is reflexed and twice as thick at the lateral awns.[2]
Distribution
A. virgata can be found in the southeastern United States from Texas to New York. [1]
Ecology
Habitat
A. virgata proliferates in moist to wet pine savannas, wet pine flatwoods, mountain bogs, and other moist habitats. [3] Specimens have been collected from open pine savanna near a marsh edge. [4] In Florida, A. virgata has been found to be frequent in the communities it is found.[5]
Phenology
A. virgata does not hold up well against transplanting. [6]
Fire ecology
A. virgata flourishes when the following burning treatments are applied: periodic summer and annual winter. [7]
Use by animals
A. virgata has poor forage value. [8]
Conservation and Management
A. virgata is listed as: a "special concern" species by the Connecticut Department of Environmental Protection, endangered by the Maryland Natural Heritage Program, and threatened by the Massachusetts Natural Heritage and Endangered Species Program, the Pennsylvania Department of Conservation and Natural Resources, and the Rhode Island Department of Environmental Management.
