Common name: Nakedflower tick-trefoil
Synonyms: Desmodium nudiflorum (Linnaeus) A.P. de Candolle; Meibomia nudiflora (Linnaeus) Kuntze
It occurs widely throughout the eastern U.S. and eastern Canada. 
The aboveground parts senesce during the autumn and leaves emerge around May. Flowering starts in August, and though each flower is short-lived, flowers can develop sequentially in an inflorescence. It is a nitrogen-fixing legume.
It can live in a humid climate that experiences extremes in precipitation, wind, and temperature. It is abundant in cool, temperate, continental climates with acidic, well-drained soils. It occupies areas across light and nutrient gradients, but it occurred most frequently in open and drier areas. It is found in shortleaf pine, hickory, and oak communities. Herbarium specimens report its occurrence in mesic woodland, beech-magnolia woods above a permanent streamlet, Apalachicola River bluffs and ravines, pine-oak-hickory woods, pineland near small dry sinks, shortleaf pine-post oak and red oak-mockernut hickory woods, upland hardwood forest in Florida, a wooded bank in North Carolina, rocky ridges above 100 m elevation and dry, novaculate ridges above 340 m elevation in Arkansas, mixed deciduous forest and black oak wood in Michigan, shaley shaded bluffs in Virginia, limestone bluffs in Tennessee, and mesophytic woods in Kentucky. Occurs in frequently burned post-agriculture loblolly and shortleaf pine forest. Light levels are generally shaded. Soil types include dry sandy soil, sandy loam and rich loamy soil.
Associated species include magnolia, beech, pine, oak, hickory, Mitchella repens, mockernut hickory, shortleaf pine, sweet gum, Desmodium orchroleucum, Commelina erecta, Amphicarpaea bracteata, Agrimonia, Matelea, Hexalectris, Toxicodendron, Quercus virginiana, Nyssa sylvatica, loblolly pine, and black oak.
Flowers and fruits from June to October.
Animals can act as dispersal agents since the fruit coats are covered with abundant, sticky trichomes that attach to their hair. It is generally not affected by dormant season (March-April) low-intensity fires since the heat generated by the fires does not penetrate to where the buds and rootstocks are. Huang and Boerner (2007) found that in their study, that burning alone or with thinning reduces nitrogen and phosphorous concentrations in the soil in the short-term and the long-term. However, burning and thinning increases net photosynthesis rates of D. nudiflorum in the mixed-oak forests of Zaleski State Forest, Ohio. Mean plant biomass was also about two times greater in burned and in burned and thinned plots than in control plots. It is possible that the enhancement of photosynthesis is a result of changes in the forest floor microclimate (e.g., soil temperature, soil moisture, litter depth). Also, much more nodules were found on D. nudiflorum in the burned and in burned and thinned plots than the control plots, suggesting a potential for greater nitrogen-fixing capability.
