The flowers of this family are much like the Mustards, but the stamens are all of equal length and are often more than six; the leaves are alternate and consist of three or several leaflets, with stalks, and the plant usually tastes bitter and disagreeable instead of pungent. There is no partition in the pods, which are on long, threadlike stalks; the ovary is superior and the seeds are kidney-shaped. Many flowers have only a rudimentary pistil and never produce fruit. The Caper, of which we eat the pickled flower-buds for a relish, is a shrub which grows in the Levant. The family is quite large and flourishes in warm regions.

There are several kinds of Cleomella, resembling Cle-ome, except that the pods are different.
