There is a V-shaped recess in the split where the bolt pinches the perch to the handlebars that holds the wedge. The grooved "teeth" in the wedge go against the handlebar surface. The wedge stops the perch from rotating around the handlebars when you scare yourself with the various grips and/or levers.
Both sides should have one. I made one out of a bolt. I filed it to shape and then cut it to length. It's not hardened but it seemed to help. When you don't know they are there, they get lost pretty easily.

Not always.
I've seen a few perches that have no groove for one.

Vech used to sell them. I haven't checked lately, since I wised up about removing them.
