  Philodendron X macneilianum

Title: Philodendron X macneilianum

Dear Aroiders:

Has anyone ever heard of this hybrid called Philodendron X macneilianum? It is, so far as I know, unpublished and presumably associated in some way with someone named Macneil. All I know about it at present is that it is being called this in Paris. If anyone has any more direct information on this please let me know.

Hi Tom
Hope you are well. AB Graf's Exotica lists "P. x mcneilianum (F. species no.1 x selloum), selfheading plant with large leaves almost triangular, deeply lobed and wavy; basal lobes staghorn-like, 'cold' resistant." F. species No. 1 is described by Graf as "Fosters species No.1', or "P. cymbispathum according to Barroso".
Hope this helps a little. I have a photo I can scan for you if you don't have a copy of Exotica handy. The copies I made were from an edition of Exotica at least 25 years old so I'd say the hybrid has been around a fair while.

I have another reference from a botanical encyclopaedia (unfortunately my photocopies of the Philo section didn't record the book) that says that "P.macneilianum has large, wavy, deeply lobed leaves broadly-tringular-ovate in outline". It says it is of the same parentage as P. fosteranum which has parents being P.bipinnatifidum and P. cymbispathum.

Would seem that parents are P. cymbispathum and P. bipinnatifidum and presumably Mr MacNeil did the crossing. The second article spells the name differently with an 'a', and presumably this is the correct spelling. Hope this helps

Dear Neil,

NICE detective work on tracing what this plant is! I too like to be able
to do this when time permits!
Thanks again!

Dear Neil,

Thank you very much Neil for your effective
assistance. Have you information on Mr MacNeil?
Thank you also dear Dr. Croat for your
intervention, also Hans.

I am amazed that I never noticed this thing in Exotica. I

Does your plant look like the plant pictured in Exotica

Dear Tom,

Oui, the enormous plant that we received
resembles well that which is in Exotica. I am glad to have to find his
"parents" and I want to still thank all the people who helped me
