Interpretive Summary: Interpretive Abstract In this paper we formally transfer all four known species of Lytocaryum to the genus Syagrus based on recent molecular analyses, which show it as either nested within Syagrus or a sister genus to it. Because of these conflicting results between gene and species trees, and the imperfect morphological character distinctions used to maintain these two genera, we have decided that Lytocaryum should be subsumed taxonomically within Syagrus.

Technical Abstract: Technical Abstract In this paper we formally transfer all four known species of Lytocaryum to the genus Syagrus based on recent molecular analyses, which show it as a monophyletic group either nested within Syagrus making Syagrus paraphyletic or sister to it. Because of these conflicting results between gene and species trees, and the imperfect morphological character distinctions used to maintain these two genera, we have decided that Lytocaryum should be subsumed taxonomically within Syagrus.
