Faucaria - Tigers Jaw

Information

These are just starting to really show their markings.  Some have the distinctive teeth marks, some don't.  When I collected the seeds I didn't separate them, so they could be 1 of 2 types.  

These grow, short and compact, with bright yellow, daisy like flowers forming almost on top of the plants.

When you look at the photo, with my mature plants in, you will notice that I have more tahn one variety.  I put these all togethre before I found out there were different types.  Now I like them together, because it show the differences better.  I think there may be 3 types in here.  What do you thnik?
