Serrated Spurge
Euphorbia serrata is a species of spurge known by the common names Serrated Spurge and Sawtooth Spurge. It is native to Europe and North Africa but it is present elsewhere as a weedy introduced species. This is a perennial herb growing anywhere from 20 centimeters to about half a meter in height. The leaves are long and very narrow on most of the plant, with more oval-shaped leaves toward the tips of the stems. They are finely toothed. At the ends of the branches are inflorescences of tiny flowers. The fruit is a spherical capsule about half a centimeter wide containing tiny gray seeds.
