Elevation: 1m.
Habitat: Wild Habitat
Environment description: Plants are growing in shade to part-shade of a Taxodium distichum-Nyssa aquatica dominated forested swampland associated with Adams Bayou in a wet low-lying area that is frequently inundated.
Soils: The underlying geology of this area is of Quaternary to Late Pleistocene origin and comprised of the Beaumont Formation. This formation is yellowish- to brownish-gray, locally reddish orange with very fine to fine quartz sand, silt, and minor fine gravel, intermixed and interbedded. It also includes stream channel, point-bar, cravasse-splay, and natural levee ridge deposits, and clayey fill in abandoned channels. Channel fill is dark brown to brownish-gray with laminated clay and silt that is organic-rich. Includes marine delta-front sand, lagoonal clay, and near-shore marine sand beneath and landward of bays along the coast. Depth of this unconsolidated outwash ranges from 3-100 meters thick.

The primary soil types in the collection area are classified as Cowmarsh series. The Cowmarsh series consists of very deep, very poorly drained soils that formed in mucky silty clayey alluvial deposits of Holocene age. These depressional soils are oxbows and relict channels of rivers where flooding and ponding is frequent. Slope ranges from 0 to 1 percent but mainly less than 1 percent. very poorly drained. Runoff is negligible. Frequently flooded for very long periods from February through May and surface remains saturated for very long periods once flood waters have receded.

Comment: Plant is a multi-stemmed, deciduous shrub with and upright arching loosely open habit. Plants ranged in size from 1.2-2.5 meters tall x 0.5-3.0 meters wide. Current season’s stems often green becoming grayish-brown with age; in more sun, young stems develop a wine-red coloration. Leaves are simple, deciduous and alternate; they are elliptic to oblong-oblanceolate and 2-9 cm long x 1-4 cm wide. The leaf margins are glandular-serrate. Fruit is a capsule with many borne upright on a terminal raceme. Capsules are narrow, cylindrical and come to a long point with the style persistent; size ranges from 0.7-1 cm long.
