Description

Synonym Name: Panicum laxiflorum Lam.
Dichanthelium laxiflorum is a perennial graminoid with a cespitose growth habit (FSU Herbarium).
Distribution
Ecology
Habitat
D. laxiflorum can live in disturbed areas such as clear-cuts, thinned woods, burned areas, roadsides, power line corridors, and old fields (FSU Herbarium), with clay to sandy loam soil in subtropical climates.[1] It can also dwell in dry areas,[2] like sandstone barrens communities.[2] It can be found in loblolly pine communities[3] and longleaf pine communities.[4] It also occurs in low ground hardwood communities, mesic hammocks, river banks, above lime sinks, on coastal hammocks, and near bogs (FSU Herbarium).
Phenology
Flowering has been observed in January through May, and November, and fruiting has been observed in January through June, and November (FSU Herbarium).
Seed dispersal
It can be found in the seed bank of disturbed and undisturbed sites.[4] It can also be found in the seed bank of a Florida flatwoods plant community.[5]
Seed bank and germination
From observing the results of Taft's prescribed burns, fire seems to be required for germination.[2]
Fire ecology
In an experiment by Iglay, Leopold, Miller, and Burger, D. laxiflorum had a positive response to dormant season prescribed fire and imazapyr, a herbicide.[1] Following an early dormant season, moderate-intensity burn in 1989, it rapidly increased, probably due to a stimulation if the seed bank. By 1995, D. laxiflorum occurred in 64% of the quadrats in Illinois and was the species with the greatest frequency, replacing Schizachyrium scoparium as the dominant species.[2]
