Croat, Mayo & J. Boos 2003

Przez wiele lat był uprawiany i znany jako Philodendron 'Xanadu' lub Ph. 'Winterbourn',
zanim został opisany jako gatunek.

Wygląd rośliny. Z prawej strony jest już prawie dojrzały liść.
Inny okaz.	Młodociany liść.	Dorosły liść.

2 powyższe fotografie to "australijski" Ph. xanadu lub raczej Ph. 'Xanadu'. Musimy pamiętać, że był on długo uprawiany zanim został opisany jako gatunek, a 'Xanadu' jako cultivar został wprowadzony do uprawy w Nowej Zelandii. Europejskie i amerykańskie (USA) klony nie mają tak głęboko wcinanych liści. foto (1-2) © Michael Pascall.
Co inni powiedzieli na ten temat: Julius Boos (2009-08-22, fragments): P. xanadu is a good species of Philodendron within the group Meconostigma or self-headers. It differs from all other species of Meconostigma in details of the sexual parts of its spadix, the shape of the leaf scars on the rhizomes, shape of leaf blade, intravaginal squamules, etc... The color of its spathe is different to P. bipinnatifidium (we must remember that it was brought into cultivation from Australia with a note that it was a "sport" of P. bipinnatifidum), and blooms more sparingly, It was most probably received in Australia as as seed ex: the nursery of Alvim Seidel in Brazil. In tissue culture it becomes very "plastic" in its vegetative features, mainly by the leaf blades retaining juvenile features (reduced rear lobes of the leaf blade) for many years, up to 20 years or more, even when planted in the ground... In older literature (by Dr. Eduardo Goncalves?) I recall reading that there is a group of plants in the highlands which were being discussed as possible P. "selloum" which bore a purple/scarlet spathe, while other P. "selloum"/P. bipinnatifidum bore blooms with green spathes... I am convinced that there is a complex of Meconostigma in the wilds of Brazil into which P. xanadu falls (or which are P. xanadu) which bear blooms with purple-scarlet spathes. Maybe we will get lucky, and one of the many Philodendron experts who work in Brazil will come up with a review of this group in the near future? Brian Lee (2009-08-25, a fragment): It is entirely possible that hybrids of Philodendron xanadu and Philodendron bipinnatifidum exist. I would think that it would be more plausible that the original hybrids occurred in Brazil at Seidel's nursery. I say this as the tissue cultured examples do not shed much pollen until years down the line as the effects of the tissue culture chemicals wear off. That is not to say that someone hasn't done it. I also do not know the influence of the tissue culture on the receptivity of the female flowers which could be a factor restricting pollination. I have heard of people trying to pollinate Philodendron xanadu, but, I would love to hear if anyone produced viable seeds. To date, I have not heard of this. There is also a tissue cultured Philodendron 'Showboat', that is Philodendron xanadu, but a larger selection or one with less of the chemicals influencing dwarfed growth. Julius Boos (2009-08-29, fragments): I would tend to doubt that any "clones" of P. xanadu are hybrids with P. bipinnatifidum, as they are such very different species, one to the other. P. xanadu has scarlet/purple spathes, and fewer and much smaller blooms which are differently shaped to the huge "plantain-shaped" blooms of P. bipinnatifidum... If there was a hybrid, one could expect to see a certain amount of "mixing" of these features, I have seen none so far. Brian Lee (2009-09-02): At this larger size, it is interesting that your plants still retain the small leaf blade typical of younger plants. As the tissue cultured plants outgrow the chemical cocktails, the blades widen and the lateral lobes and the back lobes develop more fully. The general size of the blades also increase by two or three times. As far as blooming, it has been noticed that most male flowers shed very little pollen. I do not know if the receptivity of the female flowers are affected by the tissue culture process, but, this is also a possibility I have not heard of any Philodendron xanadu hybrids from the tissue cultured plants.
