Temperature regulation by the inflorescence of philodendron.
The inflorescence of Philodendron selloum temporarily maintains a core temperature of 38 degrees to 46 degrees C, despite air temperatures ranging from 4 degrees to 39 degrees C, by means of a variable metabolic rate. The heat is produced primarily by small, sterile male flowers that are capable of consuming oxygen at rates approaching those of flying hummingbirds and sphinx moths.
