Environment description: Plants are typically found growing in saturated streamside wetlands of deciduous woodlands that drain toward the Middle Branch White Clay Creek. Plants grow in high understory shade with dappled to indirect sunlight; some plants in the populations receive a few hours of direct sunlight. Slope: 0 to 3 percent. Aspect: Various. Soils found in the areas where this collection was made are comprised primarily of Baile silt loam (Ba), Hatboro silt loam (Ha), and Glenelg silt loam, 8 to 15 percent slopes (GgC). Baile silt loam consists of very deep, poorly drained, moderately low to moderately high saturated hydraulic conductivity, soils on upland depressions and footslopes that were formed in local alluvium over residuum from acid crystalline rocks, chiefly mica schist and granitized schist and gneiss; slope ranges from 0 to 8 percent. Hatboro silt loam consists of very deep and poorly drained soils formed in deposited alluvium derived from metamorphic and crystalline rock. They are on flood plains. Slopes range from 0 to 3 percent. Glenelg silt loam, 8 to 15 percent slopes consists of very deep, well drained soils formed in residuum weathered from micaceous schist on uplands of the Blue Ridge and the Northern Piedmont. This soil is undifferentiated, mostly poorly drained sandy bottomland soils intermingled with decomposing organic litter and eroded silts and clays due to erosion.

Comment: Plants are clumping, deciduous, herbaceous perennial plants. Mature plants reach 1.5-2 meters tall. Threes-sided papery capsules are borne on terminal panicles with flat winged seeds inside. Leaves are simple, alternate, and ovate to ovate-elliptic with a strongly pleated veining appearance. Plants have dense whorls of leaves along the entire stem that have the superficial appearance of corn; hence, the common name corn-lily. Infrequent in wetland and seep areas; plants occasionally found scattered in the understory of the woodlands. Seed collected from more than five plants.
