Top left two and bottom right are ariocarpus retusus scapharostaroides, bottom left obregonia denegri , bottom middle astophytum jamuave and top right is ariocarpus hintonii prbably my fav of all ariocarpus.

Hey CC you need to give us some sort of explanation & description... there may be more people like me out there with no idea what these are but ill have a crack and say ariocarpus retusus & astrophytum blah blah blah oh and one of those ario's with the wrinkled tubircles in top right... thats the best i can do after 8 beers.

That Hintonii is very nice. Do you have a solo pic of it ?

Ariocarpus hintonii

Stenocactus vaupelianus

stenocactus zacetacasensis

I love the long spines on this one.

I have lots of this species some with field collection no's and others i purchased with names but i am sceptical of some names and am aware that there a lots of hybrids and some seed i have raised show alot different characteristics.

those plants look wicked dont they... i bought one recently named echinofossilocactus or something like that... did they merge this species?

was formely echinofossilocactus now stenocactus although many still use echinofossilocactus i its just to long to write echinofossilocactus and i get sick of writing echinofosssillacactus so i use stenocactus.

I don't like echinofossulatus as a name, and it's older too. On the other hand, steno = narrow in greek, so stenocactus is a very appropriate name for this genus. I had 7 of them and I recently bought a steno crest plus some more, which were probably mis-IDed {I think my crest is supposed to be vaupelianus]. Like you said, they hybridise a lot, so sometimes they are mis-IDed or very hard to ID or more commonly they're sold unamed. I love them for this fact too, as I like to try to find out what genes are in each of them.

I love this genus as well, and my own are very different from your ones Ccook. Are these seed grown?


Great arios too

Yes these are seed grown i have many more i love the variation even in a group of seedlings there are many different ones. I think seed from these batches come from a hybrid somewere along the lines. I have plants from seed from steve brack and they seem to all be very close looking and close to descriptions will show pics later.
