Pollinarium

a formation in the flowers of Orchidaceae that consists of a pollinium, a stalk, and an adhesive disk. The adhesive disks stick to the head of an insect, which carries the pollinarium to another flower. The pollinia land on the lobes of the stigma and deposit the pollen, thus ensuring cross-pollination and subsequent fertilization in most of the ovules.
