Taxonomic notes
Description
Panicum verrucosum is an annual graminoid species. [1]
Distribution
Ecology
Habitat
P. verrucosum occurs in moist to wet, sandy or loamy soils, including sandy loam, loamy sand, and sandy peat. [2] It can be found in pine-wiregrass savannas, wooded floodplains, pond pine-titi peat swamps, sandhills, cabbage palm-mixed hardwood hammocks, and bordering bodies of water, including Cypress-gum ponds, lakes, Hypericum bogs, and ephemeral depression marshes. [2] Furthermore, this species appears in some disturbed areas, including near trails and borrow pits, and in ditches, clear-cuts, and power line corridors. [2] Associated species include Pinus palustris, Andropogon ternarius, Muhlenbergia expansa, Aristida stricta, Cyrilla, Ilex, Myrica, Cypress, Liquidambar styraciflua, Hypericum, Xyris, Rhynchospora, Schizachrium, Eupatorium, Scleria, Plea, and Zigadenus. [2]
Phenology
Flowering and fruiting have been observed in June, September, October, and December. [2]
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [3]
Seed bank and germination
The species showed a significant increase in abundance after tilling (soil disturbance), and was abundant in seed banks. [1]
Fire ecology
P. verrucosum is found in cut-burned areas of a Chamaecyparis thyoides stand in the Great Dismal Swamp. [4]
