Here is a time lapse set of photographs of my Philodendron Bipinnatifidum. The photographs were taken one hour apart beginning early afternoon over a period of 8 hours. The Spadix moves forward and then starts to heat up. I measured it reaching a temperature of 43 degree centigrade, some 20 degree centigrade hotter than room temperature which was 23 centigrade. The Spadix also emitted a lovely peppery warm musk like scent for about two hours. If I could bottle that I'd be very happy! :)
If you go to this link you can view a visual timelapse of the event discussed in this thread: http://www.botanicalgarden.ubc.ca/forums/showthread.php?t=38988&highlight=heat The perfume is known to science as a pheromone. It is produced at female anthesis to attract the appropriate male insect pollinator to cause pollination. Often, only a single species of male insect is involved but he also brings along his mate. That male insect can detect a single molecule of the pheromone from 1 mile away since it is thought the pheromone smells like the female of his species who is ready to reproduce.

One insect only? Crikey, that's limiting itself! Won't any insect pollinate it just by walking up & down it? Lovely website by the way, many thanks for the link : )
Chris, may I use one (or a few) of your other photographs from the original thread to accompany this? I've never done a time-lapse sort of thing with BPotD before, so I'd prefer to "lead" with a typical static photograph, then include the timelapse in the entry.
Daniel, many thanks for asking. I'd be both delighted & honoured! : ) Best wishes, Chris <edit> Daniel, If you'd like higher resolution images than those I posted please let me know.
Chris can give you a direct answer but if you read this thread you'll know a great deal more: http://www.botanicalgarden.ubc.ca/forums/showthread.php?t=38988&highlight=heat
Hi Eric, sorry I only clocked your post just now. I used an infra red thermometer. You point it at the object you want to know the temperature of, pull the trigger and the reading appears on a LCD display on the rear of the unit. I originally bought it to measure the cylinder head temperature of a motorcycle engine. See photos.
