The orchid's flower is made up of three sepals (external) and three petals (internal). In most species, one of the petals is outstanding and has a special name, the lip or labellum. It usually has intense colors and serves as an attractive landing ground for pollinators. In the center of the flower is a specialized organ, the column, resulting from the fusion of the stamens (male reproductive organs) and the pistil (female reproductive organ). On the top of the column the pollen grains are grouped in small masses or pollinia, protected by the anther. Immediately below, a small cavity represents the feminine receptive portion, the stigma.
