Description

Ricinus communis, the castor oil plant, is a species of flowering plant in the spurge family, Euphorbiaceae. It is the sole species in themonotypic genus, Ricinus, and subtribe, Ricininae. The evolution of castor and its relation to other species are currently being studied using modern genetic tools. It reproduces with a mixed pollination system which favor selfing by geitonogamy but at the same time can be an out-crosser by anemophily or entomophily.
