Abstract

A family of low shrubs or wiry herbs, there are only 200 or so species worldwide in eight genera. Leaves are entire and simple, and usually alternately arranged. Perfect flowers are hypogynous and regular, but for the calyx, which has two reduced sepals. Stamens vary in number. The fruit is a capsule, dehiscent to its base. Photos were taken by Martin Thomas, Ruth Newell, Sean Blaney and David Mazerolle.
