Abstract

Shrubs and trees numbering 65 species comprise this monogeneric family. Typically bearing simple alternate leaves, these woody plants produce racemes or panicles of white flowers. Perfect flowers are usually regular and always hypogynous. Calyx is persistent. Nectar glands are present. Ovary is superior. Fruit is a capsule; seeds are winged. Photos were taken by Martin Thomas and David Mazerolle.
