Desmodium perplexum is a species of flowering plant in the legume family Fabaceae. It is native to eastern North America.
Description[edit]
Desmodium perplexum is a herbaceous perennial plant. It has trifoliate leaves with petioles at least 10 mm (0.39 in) long. Its fruit is a type of legume called a loment that separates into single-seeded segments with hooked hairs that stick to fur and clothing.
Taxonomy[edit]
Desmodium perplexum was first described by the American botanist Bernice Schubert in 1950.[4] The specific name perplexum refers to the "perplexity of botanists" concerned with the taxon known as Desmodium dillenii Darl.[5] As "the least clearly understood species of the genus", Schubert declared Desmodium dillenii to be a nomen confusum (i.e., a "confusing name") and then attempted to resolve the confusion by splitting the taxon into two distinct taxa, one of which became Desmodium perplexum B.G.Schub.[2] The other taxon was given the name Desmodium glabellum (Michx.) DC.[6]
Desmodium perplexum is a member of the Desmodium paniculatum complex, a group of closely related taxa that includes Desmodium paniculatum, Desmodium glabellum, Desmodium perplexum, and Desmodium fernaldii. The composite Desmodium dillenii is also a member of this group but the name is no longer in use.[7]
Distribution and habitat[edit]
