Evolution of Angiosperm Pollen. 2. The Basal Angiosperms1

The systematic significance of pollen morphology in basal angiosperm clades including the ANITA group (Amborellaceae, Nymphaeaceae, Schisandraceae, Trimeniaceae, and Austrobaileyaceae), Ceratophyllales, Chloranthales, and magnoliids is discussed, as well as in related lineages, i.e., monocots and basal eudicots.

Early evolution of angiosperm pollen as inferred from molecular and morphological phylogenetic analyses

Results refute the view that granular structure supports a relationship between angiosperms and Gnetales, Bennettitales, and Pentoxylon and refute the views that alveolar exines and reticulate‐columellar Triassic Crinopolles pollen now seem equally likely.

Phylogenetic analysis of Magnoliales and Myristicaceae based on multiple data sets: implications for character evolution

Magnoliales, consisting of six families of tropical to warm-temperate woody angiosperms, were long considered the most archaic order of flowering plants, but molecular analyses nest them among other

Morphological Phylogenetic Analysis of Basal Angiosperms: Comparison and Combination with Molecular Data

Combined analyses of morphological and molecular data generally yield the same topologies as molecular analyses, but morphology overcomes weak molecular evidence in indicating that Chloranthaceae belong just above the basal grade, that monocots are related to Piperales, and that Lauraceae are linked with Hernandiaceae.
