|Seed of Iris kirkwoodiae × Iris iberica elegantissima|
What you see in the image above are seeds from the hybridization of Iris kirkwoodiae and Iris iberica elegantissima. I was hoping there would be more of them, and that I would be able to offer them to the seed exchanges. But the eleven seeds you see there (and two more I found on the ground later) are all I got.
The structure at one end of the seed which resembles a pale brown, misshapen donut is the aril; irises of this group are often called arillate irises.
