Thanks for the links Fred, the gallery section was quite informative.

The names of this genera like many others appears to be a bit of a minefield. Here's a list of correct (accepted) names and synonyms. Enjoy |

Fred, that last link above, lists 245 accepted Lithops species names. Is there any way to cross reference all or most of these species names with photos of said species? ...always nice to be able to match an accepted name to a corresponding face. That gallery link from earlier provided a helpful headstart.  www.lithops.info/en/gallery/images.htmlCute cultivars too! www.lithops.info/en/gallery/cv-images.htmldvg |

I don't think it's as easy matching a face Doug. Every plant seems to have different markings. In habitat the plants match the ambient rock colours, otherwise the grazers will remove them but in horticulture we don't weed out the sports and different colours. Humans are not so good at natural selection in plants, we tend to value the plants nature disposes of so we're counter-evolutionaries.
Looking at photos the species, to me, can be confused readily. I've seen online discussions on no id photos supplied and there's always several identifications proposed. The process seems to end when the name of least objection is adopted. We're really dependent on correct labelling of both plants and seed. The seed also needs to be carefully obtained and measures taken to prevent hybridisation.
As for numbers, there's a lot less than 245, there's only 37 species. You're counting sub-species, varieties and forms in that
I'm just waiting for a budding taxonomist to come along and rename the whole lot so he can sell his book and get his Masters or PhD. That seems to be the way it happens with other genera.

That's a good thought provoking answer Fred...lotsa meat on that bone.  Interesting comment about the pressure of these plants to conform to and fit into the color patterning of local terrain, in order to avoid detection and consequent removal from their patch by grazers...which constitutes a rejection. But once in cultivation, the pressures are different. Humans in today's modern world are pressured by advertisers and corporations to stand out, to be unique, to be special. In a batch of seed grown Lithops , it is normal that folks will most naturally be attracted to the bright, the bold, and the bizarre, anything that sticks out as very unique. Lithops strategy of not drawing attention to itself, is a strong contrast to what is appealing to humans. We really have our own inner wiring working against us here with regards to being unbiased stewards for keeping accurate representations of locale specimens in cultivation, especially with each successive generation from the seed of "human selected" cultural plants. dvg |

I'm also of the persuasion that if a plant arrives without identification and you want to name it. George, Jack, Ralph etc are a good start

Once the ol' pet rock cracks, crumbles and gives up the ghost... ...it's always reassuring to know that a living stone named Archie, can help offset the initial heartbreak and loss, and help provide the solace and support to move forward again... Really like the work you've done in bringing awareness here to this genus of plants Fred... ...and if Corky gets most of the blame for all of this, then he certainly deserves some of the credit here as well.  dvg |

Thanks for the link Fred. Looks like the splitters won a border skirmish overnight and took a bit of territory back from the clumpers... ...the species count is up to 38 now, according to this latest link. Numbers and names
swirl around, insane.
The faces remain,
all still the same. dvg |

What size in diameter can you expect some of these seedling Lithops species to spread out to in their first season of growth?
Are some of the species much faster growers than others?

A few new seedlings. Their identities have been disguised to protect the innocent.   |

I think this is a case of two flew over the cuckoo nest. These were grown from seed purchased as L. otzeniana.  At least two of them are correct |
