Lotus

 Nelumbo is a genus of aquatic plants with large, showy, water lily-like flowers commonly known as lotus or sacred lotus. The generic name is derived from the Sinhalese word Nelum. There are two species in the genus, the better known of which, N. nucifera, or "Sacred Lotus," is the well-known national flower of India and Vietnam.

This plant regulates its temperature in order to benefit insects that it needs to reproduce. When the plant flowers, it heats its blossoms to above 86℉ for as long as four days. It does so, even when the air is as cool as 50℉. The heat releases an aroma that attracts certain insects, which fly into the flower to feed on nectar and pollen. But according to Roger Seymour and Paul Schultze-Motel of Australia’s University of Adelaide, the heat does more: It rewards insects with a stable environment that enhances their ability to eat, mate, and prepare for flight.
