Translations

Pollinium

in orchids and milkweeds, a compact mass consisting of tetrads of pollen grains. A pollinium usually develops in two pockets of the anther. Its formation is an adaptation to specialized pollination by insects. In many orchids, the pollinium is part of the pollinarium; in some, it comes loose when the insect makes contact with the inner portion of the flower. In milkweeds, the pollinia are attached in pairs to sticky disks that adhere to the insect.
