About the Cover:

The background photograph shows Vanilla planifolia under cultivation in Costa Rica. The narrow green attachments are the immature vanilla beans. After harvesting they mature to a dark brown color, occasionally with visible white crystals of vanillin showing on the surface (see the article by Hocking, page 1055). The foreground shows a botanical print drawn by Gordon Winston Dillon.
