Desmodium humifusum
''Desmodium humifusum'' is a species of flowering plant in the legume family known by the common names trailing tick-trefoil, eastern trailing tick-trefoil, and spreading tick-trefoil. It is native to the eastern United States, where it has been reduced to scattered populations in the states of Massachusetts, Connecticut, and Indiana. It once had a wider distribution but it has likely been extirpated from Delaware, Maryland, New Jersey, New York, Rhode Island, Virginia, West Virginia, and Missouri.〔(''Desmodium humifusum''. ) The Nature Conservancy.〕
This plant is prostrate, its hairy stems trailing up to 2 meters long. One plant may have a large number of stems. The alternately arranged leaves are each divided into 3 leaflets up to 7 centimeters long by 5 wide. The leaves have persistent stipules which may aid in identification. The inflorescence is a raceme of purple flowers nearly one centimeter long. Blooming occurs in July and August. The fruit is a legume pod jointed into three or four segments, with each segment up to 8 millimeters long. The segments are dispersed on animal fur. This species is probably a hybrid of ''Desmodium paniculatum'' and ''D. rotundifolium''.〔Dolan, R. (Conservation Assessment for Trailing tick-trefoil (''Desmodium humifusum''). ) USDA Forest Service, Eastern Region. September 30, 2004.〕
This plant grows on sandy soils that originated from sandstone and chert. The habitat is often dominated by oaks,〔(''Desmodium humifusum''. ) Center for Plant Conservation.〕 and it may be a type of dry forest.〔
