This species and D. glabellum are the two most typical yet most difficult species to separate in NC. Learn more at Vascular Plants of North Carolina.
Traditionally, D. glabellum and D. perplexum have been segregated largely by stem pubescence type and density. In "Desmodium glabellum and D. perplexum (Fabaceae): a morphological reevaluation", Thomas presents an alternative treatment.
