Darwin observed and dissected flowers of Epidendroideae based on greenhouse specimens (Chapter 1 and 8). Observations of the same Neotropical flowers and their visiting bees by Hermann Crüger (1818-1864) in Trinidad provided additional data for Darwin. Chapter 9 much extends and expands these early studies of orchid pollination mechanics and also directs the reader’s attention to bee anatomy and diversity, ants, extrafloral nectar secreted by orchid inflorescences and the fragrance chemistry of their flowers (Chapter 3). The author presents a compelling argument that the evolution of bees and Neotropical orchids is an example of asymmetrical evolution.
