Type species.

Janusia guaranitica ( A. St. - Hil.) A. Juss. ex Endl.

Notes.

With the reestablishment of Schwannia , the recognition of Peregrina as independent of Janusia based only on the subshrub habit (vs liana) and laterally flattened stigmas (vs rounded stigmas) unnecessarily inflates the number of genera in Malpighiaceae without providing any taxonomic or systematic benefits. Since Janusia and Peregrina share non-enantioustilous flowers and androecia with five fertile stamens, without staminodes, we choose to return Peregrina to Janusia . In its current sense, Janusia comprises only two currently accepted species (one threatened species; Suppl. material 1) of subshrubs or lianas endemic to rainforests, savannas, and seasonally dry tropical forests of Argentina, Bolivia, Brazil, Paraguay, and Uruguay, South America ( POWO 2024). For an identification key for all species of Janusia , see Sebastiani (2010).
