Re: [Aroid-l] Philodendron 'Xanadu' leaf mutations

From: <ju-bo at msn.com> on 2009.02.10 at 22:50:33 Dear Zach=2C What you have observed are deformations=2C all commonly observed on this species of Philodendron. =3B =3B You will also see ''double blooms'' on one peduncle=2C ''double spadices'' within a single deformed spathe=2C etc. In time (years!) the plant MAY ''grow out'' of these chemicals and become a nice looking plant. I believe these deformations are caused by the method that this plant is produced by the millions in tissue culture=2C or by chemicals the young plants are treated with to cause dwarfing and/or many plants growing and clumping together. See my articles on P. xanadu in both Aroideana # 25 (where it is described as a new species By Dr. Croat=2C Dr. Mayo and myself) and my follow-up article in Aroideana # 31 where I touch on the ''whys'' of what chemical treatments MAY be doing to this interesting species=2C and picture plants which over years have grown out of the chemicals.

The first is that two stems have =93fused=94together =96 all the way from the base of the stem to the leaf=2C includingthe first lobe of the leaf on one side. The other possible mutation is a small extra leaf(?) risingfrom the midrib near the base of one leaf.  =3BIt reminds me of the smallleaf that grows in the middle of the cladode of Ruscus hypoglossum.  =3B(Seethis blog post with pictures: http://itinerantgardener.blogspot.com/2009/01/tricksters.html)  =3BYou can see my pictures of both mutations here: http://myfolia.com/journals/39643-weird-leaf-mutations The thumbnail images are links to the full size images onFlickr. =3B There is one image of the small=2C extra =93leaf=94 and fourimages of the fused leaves. Has anyone encountered these 2 growth habits before?  =3BArethey normal or do I have a special plant? =3B Thanks- Zach DuFran --_8041e26a-7575-479a-bd37-7193ef055c7d_----===============2592148057649282488==
