You remember Jewel Flower (Streptanthus carinatus ssp. arizonicus) from the Mustard family tutorial, of course. These are the fruits, looking for all the world like pea pods on the outside, but arranged, as we'd expect, in a spiral staircase pattern along the stem.
Multiple seeds inside. (If this were a pea pod, the seeds would alternate on either half of the pod.) Now you know : -)
