Sometimes I get ahead of myself! I just located a great
photo of Philodendron rudgeanum Schott right on the IAS website!
Botanist David Scherberich in France took the photo and I will be asking David
shortly for permission to reuse his photo. If any others have one I'd love
to see them.
I realize this is likely to be confusing so please read all of
my request before responding with a photo.
I have been researching the names
Philodendron martianum Engl. and Philodendron
cannifolium Mart. ex Kunth for a new webpage that has yet to be
I have known for some time the correct name for the species
many of us grow is Philodendron martianum (not Philodendron
cannifolium) as was recently explained by Leland Miyano on this
forum. Aroid botanist Dr. Eduardo Gonçalves in Brazil had confirmed
that fact for me late last year. What I was having trouble
understanding is why many of us believe Philodendron cannifolium
is a synonym for Philodendron martianum when neither the International
Plant Names Index nor TROPICOS stated that to be correct. Both plants
are cited to be a species but the accepted name for Philodendron
cannifolium is Philodendron rudgeanum Schott and I could not find
a source in botany that Philodendron cannifolium was a synonym for
I sent a note to my friend Leland and asked for help in
unraveling this mystery. This was Leland's response:
"Surf on to the KEW World Monocot Checklist...they have
the best explanations about Philodendron cannifolium...and it depends on
the author. Philodendron rudgeanum is totally different from
Philodendron martianum...but it does look like vine with Spathiphyllum
cannifolium leaves...so the confusion...I'll let you explain it in a better
fashion once you see the citations."
Leland also explained the common belief that Philodendron
cannifolium looked like Philodendron martianum can be
traced to A.B. Graf's book Exotica which has an incorrectly identified
photo of Philodendron martianum with the caption "Philodendron
Once I read all the Kew's material I could understand the
name Philodendron cannifolium was in fact Philodendron
rudgeanum and neither of these plants even look like Philodendron
martianum! Philodendron rudgeanum (formerly Philodendron
cannifolium) is a totally different species and has leaves
that look like Spathyphyllum cannifolium but is not a
Spathyphyllum species but is simply a Philodendron
with leaves that look like a Spathyphyllum.
Believe me, I know that last paragraph can be confusing!
I had to think about this for quite awhile to make certain I understood what the
scientific sources were saying before beginning to write my page.
So here is my photo request: To better explain this
confusion on my website I need a good photo of Philodendron rudgeanum
(formerly known as Philodendron cannifolium) so I can show my website
readers what both plants look like. If you grow Philodendron
rudgeanum and would be willing to allow me to use your photo with credit
please post it here and also send it to me at Steve@ExoticRainforest.com
Please be sure you tell me how you would like the credit to read.
At this time I don't need any more photos of Philodendron
martianum since four plant photographers have provided those
