Dear Steve,
I had a look at the photo, and do not believe this is X.
sagittifolium/robustum. The leaf tissue at the sinus of the rear leaf
lobes is full almost to the point of juncture w/ the petiole, P.
sagittifolum/robustum has a naked area at this point. If I had to
guess, I`d have to say that the plant shown is a cultivar/selection of the
one we were discussing, the X. 'albo-varigatum monstrosum' or whatever
cock-a-many name it is being called, the one w/ the little 'cups' at the
leaf-tips. The other species of Xanthosoma that I have grown which also
has this sinus full to the base, very like the one in the photo, is one
that grows from tubers you can sometimes buy at Cuban/Latin stores called
'malanga amarillo', or 'yautia amirillo'. To me this is interesting, as
Deni Bown equates and actually calls both of these plants by the same
scientific name, X. atrovirens.
I`d be interested in hearing any other opinions.
Sincerely,
Julius
I have some large variegated Xanthosomas that look like sagittifolium to
me. Photo posted in IAS ID center.
Thanks,
Steve

Dear Eric and Friends,
I do believe that what you are seeing and ID`ing as varigated Xanthosoma
are mainly a varigated form of Alocasia macrorrizos, not Xanthosoma. The
common plant sold as Xanthosoma 'albo marginata' I believe is actually an
unidentifed species of true Xanthosoma, at least according to Dr.
Goncalves, who is perhaps one of the leading expert on this group. It was
named as X. atrovirens by Deni Bown in her book, which I believe is also
an error. The species of Xanthosoma w/ the 'frills' under the leaf
blade is
also an as-yet unnamed species without a 'good' scientific name. It too
has been in cultivation for a LONG time, I have it in a book from Brit.
Guiana from 1927.
I have not seen a varigated P. bipinnatifidum (P. 'selloum') as yet, nor a
var. P. evensii or P. xanadu.
Good luck, and keep us informed!
Good Growing,
Julius.
Has anyone ever come across variegated Xanthosoma
sagittifolium or Philodendron bipinnatifidum? Both are
common here in Florida. Xanthosoma sagittigolium
'Albomarginatum Monstrosum' can be found but I am
interested in a variegated form of the huge leaf
specimens (which might be X. robustum) that are
growing in many yards.
Also, what about variegated P. x evansii or P. x'anadu?
