摘要：
Pereskia bahiensis subsp. minensis subsp. nov. is described from agreste vegetation in the South-eastern Brazilian state of Minas Gerais. The new taxon differs from P. bahiensis subsp. bahiensis by its flowers, with more numerous, rounded bracts, the conspicuously white base of the petals, the stamens densely clustered at the centre of the flowers, and its more robust habit and leaves. We provide illustrations and an IUCN conservation Red List status assessment (Critically Endangered, CR). A key for all taxa of Pereskia is also presented.
