Name:
Spartina cynosuroides - Panicum virgatum - Phyla lanceolata Herbaceous Vegetation
Reference:
Southeastern Ecology Working Gro...
Description:
This association occurs in wind-tidal oligohaline marshes. This association has numerous floristic components not occurring in other, more haline, Spartina cynosuroides marshes. Spartina cynosuroides is the characteristic species in tall, coarse marshes that vary from nearly monospecific to strongly mixed with high species richness. Locally, Cladium mariscus ssp. jamaicense, Schoenoplectus robustus (= Scirpus robustus), and Spartina alterniflora are dominant or codominant in this type. Typical tall or mid-height associates include Amaranthus cannabinus, Symphyotrichum subulatum (= Aster subulatus), Decodon verticillatus, Hibiscus moscheutos, Panicum virgatum, Rhynchospora macrostachya (= var. colpophila), Sium suave, Typha spp., and the herbaceous vine Mikania scandens. In most stands of this type, vegetation of low to mid-height marshes, e.g., Eleocharis fallax, Cyperus haspan, Pontederia cordata, Sagittaria lancifolia, Schoenoplectus americanus (= Scirpus americanus), Polygonum spp., etc., occurs as a lower stratum beneath the taller species. Phyla lanceolata is another short-statured plant that is apparently much more constant and abundant in these tall marshes than elsewhere. Plants that are particularly common in channel edge microhabitats are Asclepias incarnata, Cladium mariscoides, Lobelia elongata, Lythrum lineare, Stachys aspera, and Teucrium canadense.
