Abstract
We propose nine synonyms and five lectotypifications for South American Miconia (Melastomataceae). Miconia acreana is synonymized under M. erioclada; Miconia depauperata and M. doriana under M. paniculata; Miconia inconspicua var. glabrata under M. petropolitana; Miconia japuraensis under M. juruensis; Miconia martiusiana under M. cinnamomifolia; Miconia maximiliana under M. ibaguensis, Miconia pileata under M. ciliata and Miconia pseudonervosa under M. nervosa. We propose lectotypes for M. acreana, M. doriana, M. juruensis, M. longicuspis and M. pileata.
