Are snowdrops thermogenic?

Carolyn:

I'm not sure about the thermogenic qualities of Galanthus.

I did aim an infra-red camera on a Arum paleaestinum and the spadix showed a higher temp than the surrounding area.
The image is on Wiki Wiki.

The theory for the Arum is that it mimics decaying meat and helps attract pollinators.

If you know anyone with an infra-red camera it might be a good idea to give it a try.

There are a lot of statements out there that snowdrops are thermogenic,
i.e., produce their own heat. I have observed this in my gardens. However,
the scientific literature I have found on the subject does not list
snowdrops or their family among thermogenic plants and families. Doe anyone
know if they are and could you provide a source for the information.
Thanks.
