BA6FCF10E3EB3709B61434617539657C.taxon	distribution	Distribution. Mcvaughia is restricted to sandy soils within sedimentary basins of Northeastern Brazil, with different species being endemic to each sedimentary basin: Mcvaughia bahiana - Tucano basin, M. piauhiensis - Parnaiba basin, and M. sergipana - Sergipe-Alagoas basin (Amorim and Almeida 2015). Sedimentary basins represent conspicuous phytogeographic zones within the Caatinga domain, with a distinct biota from other areas of Caatinga over crystalline shield, holding endemism records for some angiosperm families (Cardoso and Queiroz 2007; Almeida et al. 2018; Silva and Souza 2018).	en	Almeida, Rafael F., Guesdon, Isabel R., Pace, Marcelo R., Meira, Renata M.
