Miconia galeiformis and Miconia neei (Miconieae:Melastomataceae), two new species from Bolivia.

Two new species of Miconia from Bolivia are described: Miconia galeiformis (sect. Chaenopleura) and Miconia neei (sect. Cremanium). Both species occur in Andean montane forests. Miconia galeiformis is distinctive within Miconia sect. Chaenopleura due to the presence of setose stems, petioles and abaxial leaf surface, and a large,globose stigma. Miconia neei bears unisexual flowers, and can be distinguished from similar Miconia sect. Cremanium in Bolivia based on the furfuraceous stems and young nodes, in addition to serrulate leaf margins. The documentation of dioecy in Miconia neei and the occasional occurrence of unisexual flowers in Miconia galeiformis adds to our burgeoning understanding of complex breeding systems within Miconia.
