This is an annual herb growing 10 to 70 centimeters tall with oppositely arranged, stipulate oval leaves each a few centimeters long. The male flowers are borne in spikelike clusters sprouting from leaf axils, and female flowers grow at leaf axils in clusters of 2 or 3. The fruit is a bristly schizocarp 2 or 3 millimeters wide containing shiny, pitted seeds.[4][5]
A plant of Mercurialis annua can produce up to 135 million pollen grains.
