Mcvaughia bahiana W. R. Anderson.

Notes.

Mcvaughia comprises only three currently accepted species (all threatened species; Suppl. material 1) of shrubs endemic to the seasonally dry tropical forests of Northeastern Brazil, South America (i. e., Caatinga biome; POWO 2024). For an identification key for all species of Mcvaughia , see the taxonomic treatment of Almeida et al. (2019).
