Anthers are fused to the style. Like other members of the milkweed family, milkweed's pollen grains are aggregated into a waxy mass known as a pollinium. There are two pollinia associated with each anther and they are joined by a threadlike structure called a translator. When butterflies visit milkweed flowers to extract nectar, the translator becomes entanlged around their legs. Pistils are made up of two fused stigmas, two fused styles, and two separate ovaries.
Seeds possess a tuft of hair which facilitates dispersal by the wind.
