Clarifying Early Euasterid Evolution: A Synthesis of Phylogeny, Morphology, and the Fossil Record Schori, Melanie [1]. Fruit Morphology and Anatomy in Icacinaceae. Since 2001, molecular data have clearly separated the polyphyletic Icacinaceae s.l. into several different orders. Many taxa were placed in Stemonuraceae + Cardiopteridaceae (Aquifoliales), and these have recently been studied in terms of their fruit morphology and anatomy. However, fruits of Icacinaceae s.s. (Icacinales) have not been well studied anatomically, even though the family has a significant fossil record based on endocarps. As a group, Icacinaceae s.l. have been difficult to distinguish morphologically, although fruit anatomy has indicated possible synapomorphies for Stemonuraceae (e.g., xylem fiber bundles in mesocarp). Fruits may provide insights for Icacinaceae s.s. as well. Species of 17 of the 23 genera in the family will be embedded and sectioned, allowing comparisons among genera and families, and facilitating comparisons with fossil taxa as well.
