Description Shrubs or small trees, usually scandent and armed with stout axillary spines in our species. Leaves opposite to irregularly approximate. Inflorescences usually terminal on highly modified short shoots, umbelliform or densely corymbiform- thyrsiform. Flowers small, the subtending bracteoles in a more or less contracted spiral upon the pedicel. Staminate flowers campanulate; stamens usually 6-8, unequal, widely exserted, the short tube of the filaments adnate to the stipe of the pistillode. Pistillate flowers tubular, the limb of the perianth apparently always erect, the staminodes reduced to a low, occasionally glandular-dentate disc adnate to the stipe of the pistillode. Anthocarps pentagonal-clavate, coriaceous, armed with longitudinal rows of stipitate glands upon the angles.
Habit Shrubs trees
Distribution Numerous species in the Antilles, Central and South America; southern penin- sular Florida; western Africa, southeastern Asia and Oceania. A single species is known from Panama at present.
