  Congratulations, literature mentions

Congratulations to two Aroid-L'ers, Ron Gagliardo and Tony Avent, for
mentions in the March 1997 Horticulture magazine. Ron's mention was not
for aroids, but for his breeding effort toward an all-red Venus fly-trap
(Dionaea muscipula 'Akai Ryu') - for those who may not know, Ron is very
expert in the carnivorous plant field. The article on Tony had pictures of
two aroids (Colocasia 'Black Magic' and Sauromatum venosum stems), and
mentioned several more.

Also of interest - I finally had a moment to browse the March 1997
Scientific American magazine and immediately noticed an article "Plants
That Warm Themselves" (p. 104) by Roger S. Seymour, associate professor of
zoology at the University of Adelaide in South Australia. He describes his
fascination with plant thermogenesis beginning with an encounter with
Philodendron selloum in 1972. Most of the plants mentioned in this article
are aroids, and there are references to previous articles on this subject
by this author and others. (All but one also studying aroids, the
exception on Nelumbo nucifera, the Sacred Lotus.)

The information on the metabolic pathways involved was new to me and very

What you mentioned about thermogenesis in plants is very interesting - I was
talking to a man who helps maintain all of the plants in the Indiana
University greenhouse and he had mentioned to me a funny thing that he
noticed just recently - the Monstera (exact species unknown to me) that is
about the size if a tree growing on other trees in the greenhouse apparently
heated up so much that he felt it from a distance, actually measured the
temperature, and he said it registered about 94F (is my memory correct here?
I'll have to ask him again)!

Dear Stacy: That is exciting news. I don't believe that thermogenesis
is known in Monstera but I have always suspected that they were beetle
pollinated and probably were thermogenic. Can you provide any
additional details?

Tom -
I'll see what I can find out. I looked for the man in the greenhouse that I
had talked to and missed him - I was going to tell him about that article in
Scientific American but our biology library doesn't have it yet. So when I
go again, I'll ask him about the specific plant and temperature.
