3 Ice crystal mutant (most likely ice city hybrid)
4 Ice queen
5 Corn poppy (found it listed as urahannya x correcta stripe hybrid but it has traits that make it very different from either of these parents so I kinda doubt this parentage a bit)
6 Pygmayea ice city
7 Springbokvlakensis makai mutant

So I’m searching for any information on how or where the “original” mutants were created. Most likely the first ones that were then tissue culture propagated are ice city, urahannya and atrofusca mutant (I don’t have one to show). Later on some other plants appeared like Ice queen that doesn’t seem to be an urahannya hybrid because of its traits being so unique and makai mutant that also looks very wonky and weird. These plants are barely documented and I couldn’t find any information on any of these other than urahannya
There are currently lots of hybrids just based on urahannya and ice city crossing with different other species and cultivars. They inherit these traits in different manners but It’s still unknown to me how the original plants got these traits revealed

I always thought they were anomalies that arose from TC, but I never really thought to look into it. You could try emailing George Theodoris or some of the bigger Japanese Haworthia people on IG.

Good question. Like u/GoatLegRedux I’d assumed it arose out of TC, which still might be the case. But …

* Pages 24-25 include “Rasputin Series. Mr. Kawahigashi’s H. comptoniana hybrids. Photo: Mr. K. Sakai”.
* Fig 24 is captioned “Fig. 24. Haworthia ‘Rasp 43’. Unusual, underside big rounded translucent windows. Ura Hannya Group.”
TBD whether Haworthia Society of Japan defines the Urahannya Group as including the mutants we see nowadays.
Edit: [Cactus Nishi page](http://www.cactusnishi.com/HPP/CataTop01/MTS/MTS.htm) with some mutant breeding details. Might be more clues if you want to put everything through translation. I wasn’t able to get Google Translate entire web page translation to work for me, but copy/paste text on individual plants does work.

So Ura Hannya might be a Japanese cultivar group, rather than a single cultivar. [Article here](https://alsterworthia.haworthia.org/wp-content/uploads/2015/08/alsterworthia-v5-i3.pdf) explaining these cultivar groups, with a really nice chart on how it works with pictas.
Page 3 of the [Haworthia List](http://www.haworthia.net/HaworthiaList2015-3.pdf) has publication cites in Japanese, with several rows under the spelling ‘Urahannya’.
TBD whether Haworthia Society of Japan defines the Urahannya Group as including the mutants we see nowadays.
