One of my A. gageana is showing some weird variegation in the leaf.
Iron/manganese deficiency? Virus? Other.
None of the other A. gageana are showing this.
Here is the "abnormal" leaf.
I will also post a "normal" leaf below.

Need help: Strange variegation in Gageana
"Normal" leaf.
I had a similar experience on one of my monster leaves, I put it down to a shortage of water right during the leaf development stage but mine was all withered on the side that was yellow too.
The leaf looks healthy ... perhaps a little more ruffled that the other leaves.
Even the stem is lighter/more yellow than those of the "normal" leaves.
ROX
Maybe spontaneous variegation..... otherwise ...uh I dunno LOL
Sorry
Maybe Brian will be along, I figure he's a busy boy right now, haven't seen him in a bit. He got me again on ebay this week, more blue philodendrons.
Neil-
Would you consider starting a thread on various Philodendrons? I don't have any (alright 1 house plant), but I would have fun seeing the varieties that DGers collect.
ROX
ROX,
Do a search on the philos and you will see Giancarlo with his name on almost all of them. He lives in Miami and I have seen his collection, WOW
Hap
Hap-
Will do!
Thanks, ROX
Sure Thing
Im always happy to show off, let's beef up the Adoid forum the more pictures the better.

Rox you might not like what I have to say here. As most people will not like to hear what I am about to say. If you are familiar with a virus in Cannas this virus can also transfer itself into aroids. It is a form of Mosaic virus. It is commonly spread by using the same tool to cut off leaves. Any transfer of sap from one plant to another is a way for this virus to spread. It shows itself in making the plants weaker and a bit more colorful. Your plant will not die but produce blotching and streaked marks in the leaves. I usually suggest destroying the plant to prevent spreading it to others. I only suggest keeping the plants if they are extremely rare or one of a kinds. The virus can be stopped by dipping your tools in water with Clorox added. It is a nasty thing to get and bugs can spread it rapidly. The only good thing is that it does not kill and a lot of research is being done to create a cure or resistant plants.
On a brighter note most plant have viruses like this already. Much like all people have herpes LOL. Viruses like chicken pox is a form of herpes you have a one time break out and then the virus does not show itself again. You still have the virus but it is dormant usually for the rest of ones life. This is the same for some forms of this virus. I find some plants carry the virus and never show signs of it while others will be patterned for one season and not show it again. Cannas were looked at closely and it was found that all cannas have viruses usually about 7 forms most do not show up at all. People are the same I believe most people have at least 3 to 5 viruses that stay dormant.
OK...
I was afraid of that.....
What's the call? EVERYONE PLEASE CHIME IN!!!!!
It isn't a rare plant....but it is a beautiful variegation.
If it's like herpes, then is it likely that some of my others may be infected and not showing symptoms. Therefore killing this won't prevent infection OR do I kill it to prevent spread?
I share EE with others and I DON"T want to be the source of infection!
I could quarantine this plant, but it would be a hassle!
Input?

Keep the baby......

Well when I first saw this picture ROX I thought virus.
I've seen the same thing in Hosta.
(I had to destroy 3 last Summer)
I posted a link but Dave's server must have been acting up as I couldn't get on.
Brian confirmed what I thought. A virus.
My guess is Dasheen mosaic virus.
W/ tissue culturing all the rage now some serious virus problems are finally arising.
Hostas are getting hammered and now it's showing up heavily in some Aroids.
You're was probably a TC and as you (as do I ) grow Nicotiana which is a carrier as is Canna

There are only two choices.
1) Destroy the plant and pot. Meaning plastic bag and the trash. Do not burn or compost.
2) Use the technique Brian suggests. BUT you will have to do this forever.
Shovels, wheel barrel, clippers, scissors, disinfect your hands after handling the plant, etc.......
Any liquid from that plant or it's roots can spread the virus.
Like HIV if liquid from that plant meets an opening on another plant..................
So if a bug bites it then bites another plant........
Basically while many plants can carry this virus for their entire life and show no symptoms.
Yours is Full Blown.
My choice would be to destroy it immediately.
Ric
I have thought of an alternative.
I will try to give it to a friend who doesn't have any EE, or canna, or other plants that I know spread the virus.
PS I am seriously thinking about getting rid of all my canna!
ROX
OK..now I am confused. While moving the infected plant I realized that it looks like a Macrorrhiza not a Gageana (the leaves are more arrow shaped and all point upward).
What do you think?
PS I decided to bring it to work. Part of me is curious to see how it develops.
Am I being irresponsible for letting it exist?
ROX
Here is a pic of a Gageana. Note the leaves are more rounded and aren't as upright.
ROX
But there's a possible problem. This gageana seems to have an odd leaf.
VIRUS?
This plant was next to the otherplant all summer and now in the GH. I rarely cut leaves (and I do use bleach on the scissors...but I will be even more careful in the future!) but I could have caused cross contamination.
What do you think?
I did a pretty careful check of all leaves on all plants and these seem to be the only ones ...but I am REALLY nervous! I don't want to be a source of virus for others.
ROX
Now you will be seeing shadows for a while I think...lol
I see this a lot on Colocasia in the Fall.
Looks more like loss of color from coming indoors to me.
Viruses will show first on the veins and work out.
This looks pretty uniform IMHO..
Ric
Ric-
Thanks!
What do you think about the first plant...macrorriza?
One thing I forgot to mention...it is now 3.5 feet high.
ROX
It's hard to say from the shot.
The moves we have to do obviously stress a plant.
Stress can help by causing a plant to try a little harder or...............
Ric
Now im worried
This is a recent ebay philodendron purchase that i received in the mail, the leaf was already emerging when i received it, but it developed to this strange shape and color, at first i thought it was caused due to stress of shipping while the leaf was in development but now after seeing this thread im thinking virus.
Any opinions.
Neil
"first i thought it was caused due to stress of shipping while the leaf was in development "
Me too.
I cleaned up the shot, lightened and cropped.
The pale lines appear to be running parallel w/ the central vein.
That's how a leaf is curled when emerging.
Odd shape could easily be from packing and shipping damage.
Bet the color straightens itself out w/ a few days in the Sun and the next leaf is OK.
Though Brian may have other ideas. He has much more experience w/ shipped Aroids.
I think though we may be getting carried away w/ virus phobia.
I know I did when I found the infected Hosta in my yard.
It's still really pretty rare.
Ric
I have seen the virus in Philos it tends to act a bit differently streaking slightly in leaves. It does not seem near as noticable or causes as much weakness in philos compared to other aroids. This could easily be a mutation in the leaf or just as easily a sign of the virus. The virus is very scary it can spread extremely fast I do not know of any large collection that does not have signs of it. It is found in nature and new philo species not yet named have shown signs of it. I am not sure what can be done besides prevention on my part. The truth I believe this virus maybe in every nice or well known collection soon if not already.
Thanks for the input Brian and Henry I live in hope that it's just a mutation or travel sickness.
I guess time will tell.
