Abstract
Two new species of Microlicia (Melastomataceae) endemic to campos rupestres in Serra do Cipó, Minas Gerais, Brazil, are described, illustrated and compared with their putative relatives. Microlicia rugosa sp. nov. is similar to M. minutiflora and M. martiana by having fastigiate branches, ascending, lanceolate or oblanceolate leaves with obtuse apex, attenuate base and entire margin, flower with short pedicels (1−2 mm long), magenta petals, and dimorphic stamens. Microlicia rugosa is further characterized by wrinkled surface of hypanthium and sepals, and both leaf surfaces with distinct depressions, which sometimes contain short‐stalked glandular trichomes. Microlicia viscida sp. nov. is similar to M. martiana, M. furnensis and M. rugosa mainly by having fastigiate branches, terete stems without leaves at the base and the bark gradually peeling to reveal the underlying brownish wood and leaves with similar size and shape. Microlicia viscida is characterized by a conspicuous secretion covering branches, leaves, hypanthium and sepals, giving a smooth and bright appearance. The leaf anatomy of both new species is briefly described. Microlicia rugosa and M. viscida are assessed as ‘Endangered’ and ‘Critically Endangered’ respectively, due to its limited extent of occurrence and area of occupancy, according to the IUCN categories and criteria.
