Abstract

Another monogeneric aquatic family, these plants are all annual herbs. Leaves are typically opposite and sessile, the stems lax or tenuous, slender and with few branches. Flowers are axillary, sessile or arising on short pedicels. The perianth is absent. Staminate flowers have 1–3 erect stamens; pistillate flowers produce ovaries cleft in four locules and bearing a pair of persistent styles. Fruits are dehiscent in four nutlets, each with a single seed. Photographs are provided by Sean Blaney and Martin Thomas.
