(Something)Cereus sp.? looks like Polaskia chende.

Was your Mamm actually rotting, not just with a healthy soft pink base?

Now I'm in doubt, but it's too late! It was very soft, as in almost mushy, and not evenly (did)coloured, so I'd guess yes, rotting. I hope. If not, I'll have two.

I'm quite surprised they're supposed to have soft bases.

It does look from those photos as if it was normal Mammillaria colour. Some Mamms have a lot of pink or purple colour (from betacyanin pigment, I think). Bocasana, zeilmanniana, guelzowiana and others come to mind. And they can be soft, esecially if dry, or, as now, when dormant. Soft is not the same as soft and mushy and brown when rotting. It would be remarkable to have such healthy looking roots if the base of the plant body was rotting. At least they should root well.

I wish this was my biggest mistake to date! :mrgreen: Maybe I'll pop in to the B&Q again and get a replacement!

A little update, the Mammillaria heads seem to have survived my best efforts to kill them, but I'm not brave enough to check if they rooted already.

Besides that, I've done the mistake of purchasing two more unidentified cacti and would really appreciate a confirmation of my identification efforts:

This seems to be the standard Echinocactus grusonii (or Kroenleinia grusonii as it seems to be called now?):

And here, I think, I have a young Melocactus ferreophillus, but there is quite a few similar ones:

I appreciate all help!

I appreciate this forum as a tool for identifying unknown purchases.
I posted a picture the other day of 4 new pots containing 5 plants and the replies were all very helpful considering as has been mentioned in this thread, some might be known as different names.

For example one of my purchases was identified as a Wigginsia, I had not heard of these before so back to the books and online to find this specimen is known by other names, aka Parodia sellowii or................. :???: :???: :???:

Hi Mat,
I think 'your Echinocactus grusonii' is in fact a young Ferocactus schwarzii !!
Don't know about the Melocactus (too small), but certainly not ferreophilus. That one is very rare and not seen in the commercial circuit.

I got one of the cacti with long yellow hooked spines from B&Q a while ago. My best guess was a young Ferocactus hamatacanthus v. flavispinus.

That would be a bit unfortunate as I really wanted the "regular yellow spined" E. grusonii :mrgreen: But yes, Ferocacti were my other option, let's see how it develops!

Neither or the two I have this time has hooked spines, but I got a beautiful one a month or two ago, I'll see if I posted it here. Edit: yes, it's on the previous page, I got it identified on the FB group, one more sec! Edit edit: it's the same species, but I'm still not sure which subsp., could the a "pure" one, or the sinuatus maybe. It's missing the flat spines to be var. flavispinus, shame!
