Twin inflorescence

Hi,

Came across a colony of Arisaema triphyllum yesterday that had 3 
individuals with a twin inflorescence.  Flower parts appeared to be 
normal.  The only variation (besides twinning) was that two plants had 
flowers that exibited "spotting" rather than the normal stripes found in 
this species.  Is this a common occurrence?

Arisaema rust hasn't hit as hard this year as last, but then the A. 
dracontiums aren't up yet and locally they seem much more susceptible.  
What fungicide is safe/effective for the dracontiums I've got in 
cultivation?  Last year the local population was heavily infected and I 
don't want to go another year without seed production.

Thanks,

Mark Evans
