Taxonomic Notes
Synonyms: Panicum breve A.S. Hitchcock & Chase; D. dichotomum (Linnaeus) Gould var. breve (A.S. Hitchcock & Chase) Gould & Clark; P. chamaelonche Trinius var. breve (A.S. Hitchcock & Chase) Lelong.[2]
Subspecies: Dichanthelium chamaelonche (Trinius) Freckmann & Lelong ssp. breve (A.S. Hitchcock & Chase) Freckmann & Lelong; Dichanthelium chamaelonche (Trinius) Freckmann & Lelong ssp. chamaelonche.[2]
Description
Internodes can be glabrous or puberulent, and nodes glabrous, pubescent, or bearded, but the glabrous spikelets 0.9-1.2 mm long are diagnostic [3].
Distribution
D. chamaelonche is found along the southeastern coast of the United States from Louisiana to Virginia. [3]
Ecology
Habitat
D. chamaelonche proliferates in moist pine savannas, flatwoods, and pineland pondshores [3]. It is commonly found in human disturbed habitats such as lawns, roadside ditches, and bulldozed flatwoods. Soil that is found in is usually sandy [4].
Associated species- very frequently found with Quercus cerris. Also with Rhynchospora chalarocephala, Ludwigia microcarpa, Serenoa repens , Deeringothamnus pulchellus, Ilex coriacea, Aristida stricta, Dichanthelium spp., Utricularia subuluata, Polygala lutea, and Calopogon barbatus [4].
Dichanthelium chamaelonche is an indicator species for the Central Florida Flatwoods/Prairies community type as described in Carr et al. (2010).[5]
Phenology
D. chamaelonche has been observed to flower from the beginning of spring through late fall [4].
