Rust, in other species?

[Jim McClements, Dover, DE z6]

Thanks for getting and posting the rust info. That answers the question
someone raised about alternate hosts.

However, I'd like to post another question to this group, especially since we
have an international representation. Has anyone seen a problem with rust in
any Arisaema species other than A. triphyllum, either as a primary disease,
or as spread in the garden from diseased A. triphyllum? Does the disease
occur in Asia?

We all live in fear of this. Does it really happen?

Even if someone answers in the affirmative, please report any and all
experiences with this. We have a unique opportunity to collect information
about this that has never, to my knowledge, been previously available.
