Leaflet anatomy verifies relationships within Syagrus (Arecaceae) and aids in identification

The current investigation was carried out to examine how palm anatomy may coincide with the current molecular analysis including the three recognized clades of Syagrus Mart. and to justify the splitting of acaulescent Syagrus species (e.g. S. petraea (Mart.) Becc.) into several species. Free-hand cross-sections of leaflets were made and the comparison of these verifies the relationships suggested by the molecular data. Free-hand leaflet sections were also found to be useful in the identification of otherwise difficult-to-identify acaulescent Syagrus species. The result and conclusion is that anatomical data is valuable in helping to verify molecular data and that splitting the acaulescent species of Syagrus is justified by the differences discovered in their field habit and anatomy. These differences were used to produce an identification key that is based on the anatomy.
