Three new endangered species of Trembleya DC. (Melastomataceae: Microlicieae) from Minas Gerais, Brazil

During the preparation of a monograph of Trembleya DC. (Melastomataceae) three new species were found that are here described and illustrated: Trembleya acuminata can be recognized by its ovate and vernicose leaves with an acuminate-cuspidate apex, 6-merous flowers, and 4-locular ovary. Trembleya botaensis and Trembleya thomazii are closely related, differing by the indumentum with only sessile glands, white/purple colored petals, calyx lobes without a glandular apical seta, and by the apically rounded connective of the antesepalous stamens in Trembleya thomazii.
