Affiliation:Department of Botany, University of Massachusetts, Amherst, Massachusetts 01002, U.S.A.
Abstract:In an earlier paper, which includes pollen descriptions for 93 genera and approximately 430 species of the large tropical family Annonaceae, the author laid the foundation for a generic reclassification and natural phylogeny of the family based largely on comparative palynology. The present paper includes generic pollen descriptions for an additional 12 genera and 18 species of Annonaceae.
