Abstract

Mostly of the tropics, 2000 species are included. Typically plants have milky sap and simple opposite leaves. Most are herbs, a very few are shrubby. Five-merous flowers are perfect and regular. Corollas are sympetalous, tubular or salverform, the lobes overlapping. The stamens are inserted, alternating with the corolla lobes. Ovaries number two, stigma one. Fruits are a pair of slender follicles, containing many seeds. Photographs by Sean Blaney, David Mazerolle, Andy Dean and Ross Hall.
