Abstract

Throughout the taxonomic studies towards the global revision of the genus Cuphea, two new species endemic to the state of Minas Gerais, Brazil, and classified in C. sect. Euandra subsect. Hilariella, were identified: C. dryadica from the Serra da Mantiqueira complex, in the Atlantic Rainforest, and C. venosa from the Septentrional block of the Serra do Espinhaço, in the Cerrado biome. Both species are described, illustrated, commented on their ecological aspects and taxonomic affinities. According to a preliminary assessment of the conservation status, the new species were categorized as Critically Endangered.
