Varieties: Eragrostis hirsuta var. hirsuta; E. hirsuta var. laevivaginata Fernald[2]
Description
E. hirsuta is a perennial graminoid of the Poaceae family native to North America. [1]
Distribution
E. hirsuta can be found along the southeastern coast of the United States from Texas to Massachusetts, excluding Indiana and Pennsylvania.[1] It is also native to Central America.[2]
Ecology
Habitat
E. hirsuta is found in fields, roadsides, clearings, and disturbed habitats. [2] Specimens have been collected from open flatwoods, small limestone glade, margin of shallow pond, open sand of vacant lot and other disturbed areas, hardwood hammock, mixed hardwood forest, and pine-oak woods. [3] It is listed by the USDA Natural Resources Conservation Service as a facultative upland species, where it most often can be found in non-wetland habitats but can occasionally be found in wetland areas.[1]
Associated species include Aristida sp., Eragrostis elliottii, Eragrostis oxylepis, Eragrostis sp., Sporobolus sp., Juniperus sp., Paronychia sp., Croton sp., Vaccinium stamineum, Pterocaulon sp., Helenium amarum, Elephantopus nudatus, Muhlenbergia capillaris, Schoenus nigricans, and others.[3]
Phenology
This species generally flowers from July until October.[2]
Seed dispersal
This species is thought to be dispersed by gravity. [4]
Seed bank and germination
E. hirsuta has been found in the seed bank of its native communities even when herbaceous vegetation is not found.[5]
Herbivory and toxicology
E. hirsuta consists of approximately 2-5% of the diet for various terrestrial birds.[6]
