Scanning electron micrograph (SEM) of an anther from a wild sun spurge (Euphorbia helioscopia) flower bursting with pollen cells. This plant is the most common type of Spurge in Ireland and is usually found growing on waste ground. Like others plants in this family, the little flowers lack petals and sepals, instead having a circle of yellowish bracts enclosing a single female ovary that is surrounded by a cluster of male flowers. Also known as mad-woman's milk and wart spurge, the latex in the stem of the plant is toxic. It is used in the pharmaceutical industry. Magnification: x169 when printed at 10 centimetres wide. | |
