Euphorbia serrata

Euphorbia serrata is a species of spurge known by the common names serrated spurge and sawtooth spurge, and also known as Tintern spurge and upright spurge.[1] It is native to Europe but it is present elsewhere as a weedy introduced species.[2][3] This is a perennial herb growing anywhere from 20 centimetres to about half a metre in height.[2] The leaves are long and very narrow on most of the plant, with more oval-shaped leaves toward the tips of the stems.[2][4] They are finely toothed.[2] At the ends of the branches are inflorescences of tiny flowers. The fruit is a spherical capsule about half a centimetre wide containing tiny gray seeds.[2]
