  Is Philodendron bipennifolium formerly known as Philodendron panduriforme?
From: "ExoticRainforest" <Steve at ExoticRainforest.com> on 2007.06.15 at 12:58:59(15787)
Since I began this discussion on my own website I've been hit with a fair
number of emails telling me I'm "dead wrong" and Philodendron panduriforme
is just an old name for Philodendron bipennifolium. Others try
to tell me the plants are almost identical with the exception that P.
panduriforme has rounded upper lobes and P. bipennifolium has pointed
upper lobes. And still others helped point me to the correct answer.
I've spent quite a bit of time corresponding with a number of experts and
today recieved from Julius Boos in West Palm Beach a copy of volume 9 of the
International Aroid Society's journal, Aroideana. In that journal is a photo of
the the real Philodendron panduriforme taken by Dr. Croat.
If you wish to see photos of both species and read all the
information I've collected so far click on this link.http://www.exoticrainforest.com/Philodendron%20bipennifolium%20pc.htmlSometimes
old beliefs die hard among plant collectors!
My thanks to Julius Boos for his help in tracking down the
photo of P. panduriforme. I've now updated the link on the
website with several new color photos of Philodendron bipennifolium
and the black and white photo from Dr. Croat of Philodendron
panduriforme. I hope to soon have photos of the fully adult form of
P. bipennifolium from Joep Moonen in French Guiana.
