1 & 2 look like G. batesiana to me. The third, I have as well. Still a mystery to me...bought at a C&S show, tagged as Gasteria monstrose. I think it may be a cross.

The two on the left are, I'm pretty sure, clones of batesiana - one of my favorite species. I've had the one on the right, too, but I can't remember what it is. I'm sure someone here will have an ID for you.

I have the third, and for me it was labeled Gasteria nigricans monstrose by a fairly reputable local grower.

Thank you Ladies....
