Is it a numerically challenged trillium? 

This is a plant that just appeared in my garden.  The plant was a normal plant the year before.  The year after these pictures were taken the plant reverted back to a normal trillium form. 

All it wants is for you to leaf it alone.

The name Dillium came from fellow trillium enthusiast and author, Don Jacobs. Di being Latin for 2. 

This is a T. underwoodii f. dillium.  It was found in Alabama growing among several hundred other T. underwoodii in a powerline right-away.  All flower parts are in multiples of 2.
