Name:
Aquilegia canadensis - Asplenium (heterochroum, X heteroresiliens) Herbaceous Alliance
Reference:
Southeastern Ecology Working Gro...
Description:
Limestone outcrops in the southeastern Coastal Plain. These are generally small outcrops, typically partly or fully canopied by trees rooted in adjacent forest communities. Characteristic mosses include Anomodon attenuatus and Conocephalum conicum. The alliance occurs on limestone outcrops 1-5 m high, on lower slopes adjoining bottomlands, mostly to entirely shaded by trees rooted in deeper soils of adjoining forests, but with highly distinctive floristic composition. Shrubs and woody vines, such as Decumaria barbara, Hydrangea quercifolia, Ptelea trifoliata, Acer barbatum, and the alien Lonicera japonica, are sometimes rooted in solution pockets in the top and sides of the outcrops and can be locally abundant. Herbaceous species include Aquilegia canadensis, Polymnia laevigata, Thelypteris kunthii, Asplenium heterochroum, Asplenium X heteroresiliens, Asplenium platyneuron var. platyneuron, Cystopteris tennesseensis, Pilea pumila, Laportea canadensis, Pachysandra procumbens, Urtica chamaedryoides, Melica mutica, Arenaria lanuginosa, Chaerophyllum tainturieri, Arabis lyrata, Oxalis sp., Arenaria lanuginosa, and Carex willdenowii. Bryophytes are locally abundant, and include Anomodon attenuatus, Conocephalum conicum, and Marchantia sp. The lowermost portions of the outcrops are very rarely flooded by extreme flood events.
