Evolution of orchids
WebThe pollination of orchids is a complex chapter in the biology of this family of plants that are distinguished by the complexity of their flowers and by intricate ecological interactions with their pollinator agents. It has captured the attention of numerous scientists over time, including Charles Darwin, father of the theory of evolution by natural selection. Web2005). Selection pressure on some orchid taxa (groups of related orchids) has resulted in the evolution of dramatic morphological (physical and structural) differences among orchid lineages (Kew Royal Botanic Gardens 2013). One unique trait that has evolved in orchids is the fusion of the stamens (all male reproductive parts—anthers and
