This chapter brings together aspects of floral development and evolution in angiosperms
derived from the diversity of structures of extant plants. It provides a framework especially …

Flower morphology results from the interaction of an established genetic program, the
influence of external forces induced by pollination systems, and physical forces acting …

Phylogenetic relationships among many lineages of angiosperms have been clarified via
the analysis of large molecular data sets. However, with a data set of three genes (18S …

Merism in flowers is the result of a combination of a whorled phyllotaxis, the proportion of
relative sizes of floral organs and flower meristem, and pressures from external organs …

The evolution of selected characters of the perianth, androecium, and gynoecium was
reconstructed on a modification of the recent three-gene topology for angiosperms to …

While stigma anatomy is well documented for a good number of species, little information is
available on the acquisition and cessation of stigmatic receptivity. The aim of this work is to …

The Caryophyllales have the highest diversity in androecial patterns among flowering plants
with stamen numbers ranging from 1 up to 4,000. Thanks to the recent progress in …

Compared to animals, plants have been largely neglected in evolutionary developmental
biology. Mainstream research has focused on developmental genetics, while a rich body of …

Most angiosperms have gynoecia with two to five carpels. However, more than five carpels
(here termed 'multicarpellate condition') are present in some representatives of all larger …

Seventeen morphological characters are described and plotted on a phylogeny of the
eudicots. The distribution of perianth characters demonstrates that the currently held view …
