Flowers on the Tree of Life by Livia Wanntorp, Louis Ronse De Craene (editors)

By Livia Wanntorp, Louis Ronse De Craene (editors)

Genetic and molecular experiences have lately come to dominate botanical study on the fee of extra conventional morphological methods. This huge creation to trendy flower systematics demonstrates the good capability that floral morphology has to enrich molecular information in phylogenetic and evolutionary investigations. Contributions from specialists in floral morphology and evolution take the reader via examples of ways plant life have diverse in a wide number of lineages of extant and fossil flowering crops. They discover angiosperm origins and the early evolution of vegetation and examine the importance of morphological characters for phylogenetic reconstructions at the tree of existence. the significance of integrating morphology into glossy botanical learn is highlighted via case reports exploring particular plant teams the place morphological investigations are having an immense influence. Examples contain the explanation of phylogenetic relationships and figuring out the importance and evolution of particular floral characters, akin to pollination mechanisms and stamen and carpel numbers.
