Two new species of Microlicia (Melastomataceae) from Goiás state, Brazil

Abstract

Microlicia attenuata and M. versianeae, endemic to the state of Goiás, Brazil, are described, illustrated, and the preliminary conservation status for both species is provided. Microlicia attenuata differs from putative relatives in having few stalked glands in the branches, and sessile, golden glands sparsely distributed on the abaxial surface of the leaf blades, hypanthia, and sepals, while the adaxial surface is glabrous. In addition, it has lanceolate or obovate-lanceolate leaf blades that are semi-amplexicaul at the base, white petals, and yellow stamens, with polysporangiate anthers. Microlicia versianeae can be recognized by a pale-greenish hypanthium (when dry), white petals, dimorphic, concolorous, yellow stamens, and polysporangiate anthers. The branches, leaves, hypanthia, and sepals are covered only by sessile, golden glands. The leaves are imbricate, with the blade narrowly-lanceolate, discolorous, and revolute at the margin.
