	Finally, somebody has mentioned the magic word 'greasy.'   Greasy 
spot is a common occurrence on iris foliage in the summer in the South.
It is caused by rainfall and is found in beds where irises are planted
rather close together.  I find it in beds but not often on plants lined
out.  While it may be unsightly, it is not really a problem because it is 
easily removed by dishwashing liquid.  With  plants I am shipping, I
sometimes have to use a wash cloth and scrub 'behind those iris ears.'
I think it is caused by rain splattering moldy soil up on the leaves, but
it doesn't penetrate the leaves so is easily removed by the above
