Morphological Phylogenetic Analysis of Basal Angiosperms: Comparison and Combination with Molecular Data
We have amassed structural data for 108 characters and 52 taxa of magnoliids and basal monocots and eudicots, including observations by P. K. Endress and A. Igersheim on flowers. These data wereExpand

Sources of error and confidence intervals in estimating the age of angiosperms from rbcL and 18S rDNA data.
Molecular estimates of the age of angiosperms have varied widely, and many greatly predate the Early Cretaceous appearance of angiosperms in the fossil record, but there have been few attempts toExpand

Reconstructing the ancestral angiosperm flower and its initial specializations.
Increasingly robust understanding of angiosperm phylogeny allows more secure reconstruction of the flower in the most recent common ancestor of extant angiosperms and its early evolution. TheExpand

Angiosperm pollen zonation of the continental cretaceous of the Atlantic coastal plain and its application to deep wells in the Salisbury embayment
Abstract This paper presents and illustrates an informal palynological zonation of the pre‐Magothy continental Cretaceous sediments of the Atlantic Coastal Plain (Potomac Group, Raritan Formation),Expand

Hydatellaceae identified as a new branch near the base of the angiosperm phylogenetic tree
Although the relationship of angiosperms to other seed plants remains controversial, great progress has been made in identifying the earliest extant splits in flowering-plant phylogeny, with theExpand

Early cretaceous fossil evidence for angiosperm evolution
Morphological, stratigraphic, and sedimentological analyses of Early Cretaceous pollen and leaf sequences, especially from the Potomac Group of the eastern United States, support the concept of aExpand

Seed plant phylogeny and the origin of angiosperms: An experimental cladistic approach
We present a numerical cladistic (parsimony) analysis of seed plants plus progymnosperms, using characters from all parts of the plant body, outgroup comparison, and a method of character coding thatExpand
