First published in 1862 to support Darwin's claims about the evolutionary importance of 'intercrossing', this study argues that orchids benefit from cross-pollination and that the intricate shape of their flowers evolved so as to facilitate this. It includes a brief explanation of botanical terms and is illustrated with 34 woodcuts.
