The column is designed so that a single pollination will fertilize hundreds of thousands, and in somecases millions, of seeds, so microscopic and light they are easily carried by the breeze. Surrounding the column are three sepals and three petals, sometimes easily recognizable as such, often distorted into gorgeous, weird, but always functional shapes. The most noticeable of thepetals is called the labellum, or lip. It is often dramatically marked as an unmistakable landingstrip to attract the specific insect the orchid has chosen as its pollinator.To lure their pollinators from afar, orchids use appropriately intriguing shapes, colors, and scents. At least 50 different aromatic compounds have been analyzed in the orchid family, each blended to attract one, or at most a few, species of insects or birds. Some orchids even change their scents to interest different insects at different times.Once the right insect has been attracted, some orchids present all sorts of one-way obstaclecourses to make sure it does not leave until pollen has been accurately placed or removed. By such ingenious adaptations to specific pollinators, orchids have avoided the hazards of rampantcrossbreeding in the wild, assuring the survival of species as discrete identities. At the same timethey have made themselves irresistible to collectors.1.
