Description
Desmodium viridiflorum is a perennial herbaceous species.
Distribution
It is distributed widely throughout the eastern U.S. (NRCS Plants Database).
Ecology
It is a legume with a relatively high nitrogen-fixation rate and acetylene reduction rate (Hendricks et al 1999; Lajeunesse et al 2006).
Habitat
In the southeastern coastal plain it is associated with open, frequently burned longleaf, shortleaf pine-oak-hickory, loblolly pine upland native and old-field communities and open upland hardwood forests (Ultisols) (Lajeunesse et al 2006, FSU Herbarium). It occurs in both native (never plowed) areas and in old-field habitats and areas with recent soil disturbance (FSU Herbarium). It is found on loamy sands and sandy loams (FSU Herbarium).
Phenology
In the southeastern coastal plain it flowers from July-September and fruits July-October (FSU Herbarium).
Seed dispersal
Seed bank and germination
Fire ecology
It is noticeably more abundant in burned plots, as the density in an Oconee National Forest plot, which had no history of burning, was 28 individuals per ha while the densities in two Piedmont National Wildlife Refuge plots, which were burned in the dormant season every 4-5 years, were 2,563 and 3,953 individuals per ha (Hendricks et al 1999). Regularly burned sites are likely essential for the establishment and persistence of D. viridiflorum populations large enough to significantly affect nitrogen availability (Hendricks et al 1999). It needs to have enough moisture; in the event of a drought, water stress is suggested to contribute to loss of leaf area, which reduces the photosynthate available to maintain high nitrogen-fixation rates (Hendricks et al 1999).
