Suessenguthia is a small genus of six species (Schmidt-Lebuhn 2003). These are shrubs to treelets that genrally occur in wet or riparian habitats in the eastern Andean foothills (Bolivia, Peru, and adjacent lowlands in western Brazil).
Recent phylogenetic analyses suggest Suessenguthia is paraphyletic and that Sanchezia is monophyletic and nested within it (Schmidt-Lebuhn et al. 2005). The two genera bear many morphological similarities, but Suessenguthia species have 4 fertile stamens with anther appendages (vs. 2 fertile, unappendaged stamens in Sanchezia).
