They definitely look like Arabicums of some form. There are quite a few out there. There are what some call super compact and the Thai Soco's have a slight difference in growth.
The flower color on most Arabicums is pink (different shades) and a few white or red.
Either way Christine, you have yourself some very nice looking plants there.

Rick

I agree with Rick, those do look like A.arabicums. I am not sure what form, but they do look good.

You have made my day. I'd been doing a lot of reading on them and was thinking about trying to grow one but I already had 2 and I didn't even know. Is there anything extra that I need to know or do to care for these babies. I've read a bit about cutting the leaves in half, think it was called ballooning to help caudex growth and it's good to do it on arabicum.

Christine,
I have done the ballooning with one of my plants and it did stunt the leaves and kept them small. Have left it now and the leaves are becoming lager.
All tho mine is with an Obesum.
I would leave yours as is. Give good sun. They are genetically meant to grow large wide caudex's and yours are definitely on their way to this.
Rick

Thanks Rick. I will leave them alone then. Appreciate the help.

They look great, Christine. I'm glad you decided not to expose too much of the caudex--the more time under the soil, the faster they gain girth.

Thanks for the tip Pagan, I will try to remember that. I have potted them in very small bonsai pots too so that should hopefully help with width.
