Variety: D. commutatum var. ashei (J.A. Shultes) Gould
Description
D. communtatum is a perennial gramioid of the Poaceae family that is native to North America. [1]
Distribution
D. commutatum is found throughout the eastern United States, reaching as far west as Texas and as far north as Maine and Michigan. [1]
Ecology
Habitat
Common habitats for D. commutatum include low, shaded, moist woodlands and edges of woodlands, as well as dry, thin, and rocky woods and thickets. [3]
D. commutatum has a medium tolerance for drought and shade. [1]
Specimens of panicgrass have been collected in habitats that include drying loamy sand, near limestone wooded area, hardwood hammocks, longleaf pine woodland, dry sandy soil, flat oak woods, margin of field, dry banks, slash pine savanna, edge of wooded floodplain, swamp clearing, oak hammock, oak woodland, mixed hardwood forests, shaded hardwood, and swamp forests. [4]
This species does not require a moist environment but it can grow in wetter condition. [1]
Phenology
D. commutatum will typically bloom during spring, with April producing the majority of blooms. [5]
Seed dispersal
This species is thought to be dispersed by gravity. [6]
Fire ecology
D. commutatum has no tolerance for fire. [1]
Use by animals
This grass can be a supplementary food source for many terrestrial birds. [1]
Conservation and Management
D. commutatum is considered endangered in the state of Illinois. [1]
