Sapium is a genus of flowering plants in the family Euphorbiaceae. It has a pantropical distribution.[2] Species are known commonly as milktrees.[3]
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.[2]
Species
The taxonomy of the genus is difficult. Authors include up to 125 species.[2] The Old World species were redistributed into other genera in a 1996 monograph, leaving only 21 Neotropical species in Sapium.[4]
