Description
Ditrysinia fructicosa is a monoecious shrub. It may reach a height between 1.5 and 2.5 meters (approximately 5 to 8.2 feet).D. fructicosa's leaves are alternately arranged and range in shape from elliptic to lance-elliptic. They may reach a length of 3 to 7.5 centimeters (1.18 to 3 inches) and a width of 0.8 to 3.5 centimeters (0.3 to 1.4 inches).[7]
Habitat
This species is considered to be facultative to facultative wetland by the United States Department of Agriculture.[8]
In general, D. fructicosa may be found in habitats that are mostly shaded and are considered moist-to-wet, such as swampy forests.[9] However, due to its facultative nature, this species has been observed to occur in other types of habitats, such as: within a mesic woodland, within a floodplain forest, and on limestone bluffs.[10]
