Doug:

I remember seeing a video hook up from one of the Botanical gardens in
the states and in addition to the video feed there was a infrared feed
showing the temperature of the emerging spathe of an Amorphophallus
titanum. They were able to predict the flowering time based on the
temperature rise of the spathe.
