Euphorbias are an interesting group of plants and there are said to be around 1500 different species of Euphorbias in the klein karoo! Their forms are highly variable, but the genus is easy to recognise as all the species exude a white sticky latex sap when injured. Plants are generally considered to be toxic, however some species are browsed by small antelope and porcupine seem to be particularly found of the root stock of some species. Traditionally the milk sap was used as an arrow poison for arrow tips, and also used to poison fish.
Euphorbia ericoides has distinctive, large nectarines that resemble petals. In most species of Euphorbia the flowers are pollinated by wasps when they visit the flower to collect oil from the nectarines.
