ID obssesives join : a couple interesting cacti seeking identification

[mutant]

these three are seedlings, were received as such with no name. They have more or less the same size. Age unknown. They were received as an awesome variety of young seedlings - pack from a poland grower, cannot suggest buying some such a pack enough!

a columnar one and a 4 ribber at that! yeah it reminds a bit some cereus , but I think its something else. I really hope this specimen would make it , because its been through fire, wind and severe stress. When I last transplanted it , the root was almost non existent, but it made it. Seems to be making pretty long spines too. Btw, the cactus in the back is also very slow and was in the same pack and was unlabeled.. At times of great stress (and cold) it took the most wonderful blue purple colour.

same or similar kind of stress, did't even see the pup until seeing the photo I took. This too seems culumnarish, but not really echinopsis and doesnt seem to be too fast, rather on the slow side...

Perhaps the most insteresting, no ribbing, irregual, tubercloid formation. Goes slow, seems like a 'real' cactus...

So what do you think???

I think the last one is Thelocactus hexaedrophorus or something similar.

Btw, funny coincidence, I was just yesterday looking through that seller's selection and thought about buying a pack of seedlings in the spring.

First could be Cereus Stenogonus or some Cipocereus.

Second is Echinocactus Platyacanthus. Third i am thinking more towards Gymnocalycium Pflanzii.

Guess Tangich is probably right with the last One. Thelocactus hexaedrophorus looks very close!

Yes, Haku-Jo is a great Guess. If you compare it to other Echinopsis´, it looks so unique. Very interesting Hybrid.

Mutant, check out this Plant labeled Cereus Forbesii:

Thanks a lot for your suggestions, it seems the Thelocactus hexaedrophorus is spot on. Officially my second Thelo.

I guess the columnar could indeed be a Cereus or a Cipocereus, but as I see Cereus forbesii is very similar to peruvianus also mentioned as synonyms, I am reluctant to label that right now. Other than that mine looks like the ones you posted in that pic with the wide tray.. Should I note mine does more blackish darkj spines, that might fade later

Echinopsis Haku Jo seems also a good probability, it seems mine is arriving now to "maturity" of the phenotype... Nice find TH!
