A new combination for an endangered species of <i>Schwannia</i> (Malpighiaceae) endemic to the Atlantic Forest, Brazil

Schwannia was recently reestablished and circumscribed to include most of the species previously included in the non‐monophyletic Janusia s.lat. The recently published Janusia longibracteolata Amorim &amp; R.Sebast. clearly matches the morphology of Schwannia due to its enantiostylous flowers, petal margin long‐fimbriate, 6 fertile stamens, and curved style. Thus, we provide the necessary new combination, assess the species' conservation status, and provide an identification key for all species of Schwannia . With the present new combination, Schwannia includes 14 accepted species of scandent shrubs or lianas endemic to rainforests, savannas, and seasonally dry tropical forests of Bolivia, Brazil, and Paraguay.
