Sapium is a genus of flowering plants in the family Euphorbiaceae.[2][3] It is widespread across most of Latin America and the West Indies.[1][4] Many Old World species were formerly included in the genus, but recent authors have redistributed all the Old World species into other genera.[5]

Species are known commonly as milktrees.[6]
Description

These are shrubs and trees. They produce latex. The leaves are alternately arranged and smooth-edged or toothed. They are monoecious, often with spikelike or raceme-shaped inflorescences that have several male flowers, plus a few female flowers near the base. The male flowers have 2 to 4 stamens. The female flowers have 2 to 4 styles which are sometimes coiled. The flowers lack petals. The fruit has 2 to 4 lobes and may split open or not.
