There are only three plants which have yet been shown to regulate their temperature. They are the Philodendron selloun, the Skunk Cabbage, and the Sacred Lotus. The most extensive testing has been done on the P. selloun. The earliest testing aimed to do little more than determine whether the inflorescence actually had become hot. In the experiment spadices were impaled with temperature probes into the plant and the probes were connected to a machine that recorded the temperature con

The next experiment aimed to show the range of the P. selloun's heat producing capabilities. Some specimens were cut and put into indoor cabinets where the temperature could be varied. The reason the plants were placed in indoor cabinets was so that the plants rate of heat production could be measured by the expedient of measuring its rate of consumption of oxygen. Then the inflorescences were examined at air temperatures from low freezing to temperatures that are uncomfortably hot for humans. At the coldest extremes some of the inflorescences could not heat up at all. But their temperatures went to as high as 38 degrees Celsius when the environment temperature was still 4 degrees C. The cuttings became hotter as the air temperature rose further. The inflorescences peaked at 46 degrees C when the inside of the cabinet was 39 degrees C. The plant was adjusting heat production to maintain warmth in cold weather an
