Desmodium perplexum is a species of flowering plant in the legume family Fabaceae. It is native to eastern North America.
Description
Desmodium perplexum is a herbaceous perennial plant.
Taxonomy
Desmodium perplexum was first described by the American botanist Bernice Schubert in 1950.[4] The specific name perplexum is from the Latin word perplexus, which means "confused", an indirect reference to Desmodium dillenii Darl.,[5] "the least clearly understood species of the genus". The American physician, botanist, and politician William Darlington described Desmodium dillenii in 1837.[6] However, Schubert rejected the name as a nomen confusum (i.e., a term having no standing in the International Code of Nomenclature of 2018), which means "confusing name". In an attempt to resolve the confusion, Schubert split the taxon into two distinct taxa, one of which was newly described as Desmodium perplexum.[2] The other taxon was given the name Desmodium glabellum.
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 synonym Desmodium dillenii is also a member of this group.[7]
