Microlicia cogniauxiana and Microlicia naudiniana (Melastomataceae), Two New Species from the Espinhaço Range, Brazil

Two new species of Microlicia (Melastomataceae) endemic to campos rupestres from the Espinhaco mountain range in Minas Gerais, Brazil, are described and illustrated, and a discussion on leaf anatomy is also provided. Microlicia cogniauxiana is similar to M. graveolens, M. passerina, and M. tomentella by having an indumentum of stalked glands, pink to pink-magenta petals, and dimorphic stamens with bicolored anthers. It can be distinguished by its leaves with noticeable veins on the adaxial surface, and glandular-ciliate margins. Microlicia naudiniana is similar to M. nervosa, but can be distinguished by its sessile leaves with a conspicuously visible midrib on the abaxial surface and petals with rounded apex and revolute margin. It differs from M. passerina by having a sparser indumentum covering the entire plant.
