Brunfelsia plowmaniana is a species of flowering plant of the nightshade family that is native to the cloud forests of the Bolivian and Argentinian Andes. It was first described in 2012 on the basis of systematic DNA barcoding of specimens from the genus Brunfelsia. Specimens belonging to the new species had previously been placed in the polymorphic species B. uniflora, which a molecular phylogeny revealed as polyphyletic.
