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 …

New morphological and phylogenetic data prompt us to present an updated review of floral
morphology and its evolution in the basal ANITA grade of living angiosperms …

Evolutionary developmental biology (evodevo) attempts to explain how the process of
organismal development evolves, utilizing a comparative approach to investigate changes …

Plants, unlike animals, alternate multicellular diploid, and haploid generations in their life
cycle. While this is widespread all along the plant kingdom, the size and autonomy of the …

PREMISE OF THE STUDY: A diverse range of pollen morphologies occurs within the large,
paraphyletic legume subfamily Caesalpinioideae, especially among early‐branching …

Abstract Background and Aims Nymphaea thermarum is a member of the Nymphaeales, of
one of the most ancient lineages of flowering plants. This species was only recently …

An updated description of the pollination and reproductive biology of basal angiosperms is
given to show their principal associations with pollinating agents. The review considers …

Early angiosperm history was marked by a shift from a long to an exceptionally brief
fertilization process. Ovules and their associated female gametophytes became greatly …

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 …

This comparative study combines original results with a review of the literature summarizing
our present knowledge as regards nectaries in angiosperm flowers. The focus is mainly on …
