Hi, I picked these 2 cacti up the other day and was looking to ID them. Also, can I divide the one with 3 or is it best left as is? I am planning to repot and put outside in spring...thanks for any help! [/ATTACH]
The first is a Mammillaria, but I don't know much about this genus. Maybe it's a M. bocensis, or at least something from the same series. I know even less about columnar cacti but I think you should split that group. They become quite large, and I can't see why they should be grown in the same pot. The space between the bodies, dark and protected by the spines, will also provide a nice hide-out for mealy bugs and other pests.
Thanx for the help...I agree it does look like Mammillaria centricirrha. Still don't know about taller ones though.
Ok, I think that the other one is a type of Echinopsis, however, as with the diversity of them being so high, I would need to see it flower to give a proper id.
Thanx again...I looked at Echinopsis online and it looks like it probably is. I'll wait and see when (and if) it flowers!
I agree, I have not yet seen an Echinopsis with a bluish wax layer, but it often appears on the cereoids. The shape and spination points at that group too.
