Key to Syagrus identification using leaflet margin anatomy: Supplement to "A revision of Syagrus (Arecaceae)"

Presented here is an alternative method of identification for species of the Neotropical palm genus Syagrus. It makes use of anatomical characters found in the leaflet margins and can be used for identification when few other vegetative or reproductive morphological characters are available. This anatomical study demonstrates the vast diversity found in a single palm genus and may also help to gain understanding of some possible relationships within the genus.
