Taxonomic notes
Description
G. elliottii is a perennial, viney, herbacious legume. Leaves are alternate and petiolate with inconspicuous, green stipules [1]. It is a nitrogen fixing plant (Stiling et al. 2003).
Distribution
It is native to South Carolina, Georgia and Florida (Muir and Pitman 1987).
Ecology
Habitat
In the Coastal Plain in Florida, G. elliottii can be found in pine flatwoods, sandy scrub, dry pine woods, and mesic transition zones between scrubs and seepage forests. In disturbed areas it has been found in railroad gravel and in coarse sandy roadsides amongst grasses (FSU Herbarium). It is often found in Spodosol soils (Muir and Pitman 1987). Associated species include Croton glandulosus, Paspalum notatum, and Sporobolus virginicus (FSU Herbarium).
Many legume species are light sensitive, yield decreases as shade increases. However, G. elliottii possesses and adaptation to shade by producing more herbage and seed under partial shade than full sunlight (Muir and Pitman 1989).
G. elliottii is a nitrogen fixing legume and requires relatively high concentrations of other nutrients such as phosphorus and iron (Hungate et al. 2004). Phosphorus has been found to enhance yield of herbage and roots (Muir and Pitman 1989).
Phenology
The white flowers have diadelphous stamens, and can be observed blooming May through June (FSU Herbarium)[2].
G. elliottii naturally senescences during autumn months, this is a grazing management strategy to defer autumn grazing allowing depleted plants to restore vigour (Muir and Pitman 1991). It has been found to not be tolerant of repeated defoliation because this species persists primarily through survival of individual plants and vegetative propagation.
