Hello,
I've received different species of lithops. Some have Cole-numbers some don't have them. For example I have L. schwantesii ssp. schwantesii v. marthae C148 (with cole number) and the same specie without the number. Why is that?

Unlike regular field collection numbers, the Cole numbers are still applied to plants propagated for many many generations. Original Cole collected plants, or plants from original Cole seed are very rare, except for a few recently discovered locations up around C400. The Cole numbers at one time listed all known Lithops populations, although some of the more widespread species have also been collected from other nearby areas.
