Herbs or shrubs with opposite, entire, dotted, exstipulate leaves, with flowers perfect, regular, hypogynous, 4 or 5-merous, cymous and mostly yellow; sepals unequal, persistent; petals mostly oblique or convolute in the bud; stamens few or many, polyadelphous; anthers versatile; ovary compound, with styles united or separate.

becoming in fruit a 1-celled capsule with parietal placentae, or 3 to 5-celled when the dissepiments reach the center. Seeds exalbuminous, minute. (Illustrations in

Kg. 69, 278, 389, 390.)

Genera 15, species 276, very generally distributed, presenting a great variety of habit, and flourishing in all kinds of localities. The juice of many species is considered purgative and febrifugal.
