Angiosperms and their flowers have greatly diversified into an overwhelming array of forms
in the past 135 million years. Diversification was shaped by changes in climate and the …

Background Ovules as developmental precursors of seeds are organs of central importance
in angiosperm flowers and can be traced back in evolution to the earliest seed plants …

The eudicot order Malpighiales contains∼ 16000 species and is the most poorly resolved
large rosid clade. To clarify phylogenetic relationships in the order, we used maximum …

Increasingly robust understanding of angiosperm phylogeny allows more secure
reconstruction of the flower in the most recent common ancestor of extant angiosperms and …

We have amassed structural data for 108 characters and 52 taxa of magnoliids and basal
monocots and eudicots, including observations by PK Endress and A. Igersheim on flowers …

Previous phylogenetic analyses of Ranunculales, which have mostly been focused on an
individual family and were based on molecular data alone, have recovered three main …

An analysis of duplicate phytochrome genes (PHYA and PHYC) is used to root the
angiosperms, thereby avoiding the inclusion of highly diverged outgroup sequences. The …

Sequences from 14 slowly evolving chloroplast genes (including three highly conserved
introns) were obtained for representative basal angiosperm and seed‐plant taxa, using …

This is a combination of a review and original data on floral structure, development, and
biology of representatives of all families of the ANITA grade and, in addition …
