Hello again, Steve,

Perhaps Dr. oncalves can take a look at the photo of that Xanthosoma pictured in the IAS/MOBOT aroid ID site page and give his opinion. Until he manages to complete his review on the cultivated edible aroids there will continue to be confusion. Lots of the confusion began when the imports of the 'malanga' grown in Cen. America began to come in to Florida, previous to that there were mainly the white malanga (which used to be thought to be X. sagg. but is now thought to be X. robustum after Dr. Goncalves' visit to Miami/Fairchild Gardens), the red/lilac malanga which is said to be X. violacium, and the yellow malanga which was said to be X. atrovirens. Perhaps you are correct, that this varigated specimen IS in fact a true X. saggitifolium, which may have the 'full sinus' unlike the sinus w/ a naked area near the juncture as exists in X. robustum, I really am nat certain!!
I have not seen varigation in P. xanadu or P. evansii as yet.

The Best,

Julius

Dear Julius,

Thanks for the informative reply.

I have quite a few different versions of the ones known as atrovirens or 'pocket plant' in Florida. This one doesn't resemble those very much but does look like the large grocery store malangas. I hate getting stuck with just a cock-a-many name.

Steve

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?
