Desmodium perplexum
Also called Perplexed Tick Trefoil, Tick Clover
Desmodium perplexum is a species of flowering plant in the legume family Fabaceae. It is native to eastern North America. The specific name perplexum refers to the confusion surrounding this species since its initial description in 1950.
Desmodium perplexum is similar in appearance to Desmodium glabellum. The two species remained a source of confusion for botanists until a more reliable identification key became available in 2020. Consequently, much of the information published prior to that date tends to be misleading.
Desmodium perplexum is native to eastern North America. In the United States, its range extends from southern Maine, west to Iowa, south to eastern Texas, and eastward into Georgia. In Canada, members of the Desmodium paniculatum complex are known to occur in Ontario and Quebec, but since Desmodium perplexum is recognized as a synonym of Desmodium paniculatum in Canada, the occurrence of Desmodium perplexum is unknown.
