Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Possumhaw - Wax-myrtle - Laurel Greenbrier Seepage Shrubland

Colloquial Name: Possumhaw Baygall

Hierarchy Level:  Association

Type Concept: This shrubby "baygall" community occurs along the southwestern periphery of the Upper West Gulf Coastal Plain in eastern Texas, in linear seepages on lower slopes. A scattered emergent canopy of Nyssa sylvatica and Liquidambar styraciflua may be present. The shrub layer is dense and is dominated by Viburnum nudum var. nudum. Other characteristic components of the shrub stratum include Smilax laurifolia, Morella cerifera, Nyssa sylvatica, Acer rubrum, Smilax bona-nox, and Mikania scandens. Characteristic herbs include Woodwardia areolata, Rhynchospora miliacea, Boehmeria cylindrica, Dichanthelium acuminatum var. lindheimeri, Hypericum mutilum, Triadenum walteri, Hydrocotyle verticillata, Eleocharis acicularis, Ludwigia palustris, Carex leptalea, Chasmanthium laxum, Lycopus rubellus, Osmunda regalis var. spectabilis, Eleocharis tortilis, Polygonum hydropiperoides, Juncus effusus, and Osmunda cinnamomea.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: Based on Nesom et al. (1997). Examples are known from Walker and Anderson counties, Texas. The alliance placement is uncertain. The floristic and environmental affinity of this community to other shrubby baygalls placed in this alliance is undeniable, but many species characteristic of this alliance (and used as nominal species in its name) are absent from this association.

Floristics: Stands of this shrubland are dense and dominated by Viburnum nudum var. nudum. Other characteristic components of this stratum include Smilax laurifolia, Morella cerifera (= Myrica cerifera var. cerifera), Nyssa sylvatica, Acer rubrum, Smilax bona-nox, and Mikania scandens. There can be a scattered emergent canopy of Nyssa sylvatica and Liquidambar styraciflua. Characteristic herbs include Woodwardia areolata, Rhynchospora miliacea, Boehmeria cylindrica, Dichanthelium acuminatum var. lindheimeri (= Dichanthelium lindheimeri), Hypericum mutilum, Triadenum walteri, Hydrocotyle verticillata, Eleocharis acicularis, Ludwigia palustris, Carex leptalea, Chasmanthium laxum, Lycopus rubellus, Osmunda regalis var. spectabilis, Eleocharis tortilis, Polygonum hydropiperoides, Juncus effusus, and Osmunda cinnamomea. This community type lacks many species characteristic of baygall associations immediately to the east, including Magnolia virginiana, Nyssa biflora, Ilex coriacea, Persea palustris, Aronia arbutifolia, Cyrilla racemiflora, Itea virginica, Alnus serrulata, Burmannia biflora, Apteria aphylla, Mayaca fluviatilis, Habenaria repens (= Platanthera repens), Platanthera clavellata, and Pogonia ophioglossoides.
