I figured it was a
Mammillaria species - but it takes me ages to get them all. I think I will go get a bunch of naming tags - put up heaps of pics here (I won't clog your forum with pics) and get them all identified once and for all
I believe all my cacti I have are fairly common.
I used to have some awesome ones, but I sold them all off, including
A.
variegata (is it allowed to be talked about seeing as it's a succulent?) but I was lucky enough to get another one (and two pups) from this fellow in Walkamin. Though they're still very young, and don't seem as highly coloured as I am used to. He also mentioned they're slow growing... I found my ones a few years back to be prolific!
Well, the next one you can Identify then is... (haha)
