Taxonomic Notes
Synonyms: Juncus griscomii Fernald.[3]
Varieties: none.[3]
Subspecies: Juncus effusus Linnaeus ssp. effusus; Juncus effusus Linnaeus ssp. solutus (Fernald & Wiegand).[3]
Description
J. effusus is a perennial graminoid of the Juncaceae family native to North America and introduced in Hawaii.[1]
Distribution
J. effusus is found in the eastern half of the United States from Colorado and New Mexico to Maine, as well as Hawaii.[1]
A native of Europe, Juncus effusus ssp. effusus is widespread and overlooked throughout its range.[3]
The range of Juncus effusus ssp. solutus extends north into Newfoundland and Minnesota, then south in Florida and Mexico.[3]
Ecology
Habitat
Juncus effusus is found in moist soil, marshes, margins of streams, ponds, lakes, swamps, and low meadows.[2] Specimens have been collected from a wet ditch, pine forest in swamp bed, wet flatwoods, flooded pastures, seepage bog, moist sandy loam, shallow water, floodplain forest, and the edge of woods.[4]
J. effusus was found to increase in frequency in response to soil disturbance by clearcutting and chopping in north Florida flatwoods forests. It has shown regrowth in reestablished native flatwood habitat that was disturbed by these practices.[5] Furthermore, J. effusus was found to be an increaser in its short-term response to single mechanical soil disturbances.[6]
Phenology
J. effusus flowers June through September.[7]
Herbivory and toxicology
J. effusus has been observed to host planthoppers from the Delphacidae family such as Conomelus anceps and Nothodelphax occlusa.[8] J. effusus is readily eaten by marsh rabbits.[9] It is also among the 14 major fall-early winter south Florida deer foods.[10]
