<i>Tradescantia boliviana</i> (Commelinaceae), a New Combination for an Overlooked South American Species

The new combination <i>Tradescantia boliviana</i> (Hasskarl) J. R. Grant is made in recognition that it is a distinct species widespread in Peru, Bolivia, Paraguay, and Argentina, here separatedby morphological characters and distribution from its previous inclusion within <i>T. ambigua</i> Martius ex J. H. Schultes, which is restricted to northeastern Brazil.
