The origin of the angiosperms, or flowering plants, is a major question of evolutionary biology, famously described by Charles Darwin as an abominable mystery, this group arose from a yet-to-be-identified ancestral lineage and diversified to form over 350,000 species alive today. Recent advances in molecular phylogeny and genetics have combined to provide much information on the origin of the angiosperms and their synapomorphy features, such as the carpel, outer ovule integument, bisexual reproductive axis, and double fertilization. This paper provides an overview of the flowering plants or angiosperms. The unique features of angiosperms are described, and based on these features, the evolutionary and phylogenetic history of angiosperm is traced. This paper also gives details on distribution, phytogeography, growth habit, life form classes, root and shoot systems, leaves, inflorescence, flower and reproductive biology. An account is also provided on the details of genetic diversity and species diversity found in angiosperms.
