My Dear Friend Eduardo,
I have just forwarded you two notes concerning the possible ID of a Xanthosoma here in Florida to you, and I hope that after you have read them and seen the photo (in the second note) you will be able to help by giving your opinion!
I hope that you are well and happy, and that this gets to you OK, as it has been a while since I have heard from you.
Concerning the Philodendron issue which we briefly discussed (below), would it be safe to assume that since ALL the Philo. 'selloum' that are being produced by the million by tissue culture here in Florida and being sold into the landscaping trade all have very pronounced intravaginal squamules, they are in fact P. mello-barettoanum and not P. bipinnatifidium, which you report usually does NOT have these structures? The plants here all have a green spathe (see the recent paper on P. xanadu) , but may have just a thin line of purplish color along the very edge, I am not certain of this. Perhaps in the near future we should collaborate on a paper concerning the correct identification of this very important plant to commerce here in Florida?
A paper is certainly needed.
I look forward to hearing from you when you may have a moment.
Your Friend,
Julius

>>My dear friend Julius,
Just to answer your comments: Yes, I have seen real P. bipinnatifidum
in USA (mostly in Botanical Gardens), but considering you have a better
sampling of cultivated material, I wouldn?t be surprised if P.
mello-barretoanum was the main cultivated big Philo there in USA.
Philodendron mello-barretoanum was spread in Brazil by Roberto Burle-Marx,
that was part of a very active group of plant traders there in Florida, so
there was time enough to spread this plant for nurseries coast to coast.
I have seen in the wild only plants of P. mello-barretoanum with a pure
green spathe, but a few cultivated material have a spathe that is purplish
outside (mainly along the margins), so this aspect can be easily selected by
growers. Growers can do anything!
Very best
wishes,
Eduardo.
