Not only older lithops seedlings but actually 6 years old lithops seedlings. Can you believe that? These are the guys from the so-called "pumice experiment" back in 2010 which is now my standard procedure (oh my, they are so tiny there). I was disappointed for a very long time that they didn't look like "mariae" I wanted them to be - all dotty. Instead they looked like regular lesliei. However, now, 6 years later, the proper looks are apparent. The fine dotty lines and the sandy color. I remember reading that "mariae" are the largest among lesliei but mine are rather compact.
