Time to put labels, so ID please

[RICHAUD]

I agree with you : impossible to put a right name on these plants
Cereus peruvianus monstruosus or cristatus seem a consensus name

[AnTTun]

You should shop more at garden centers Richaud With labels if possible But I'll stick to .. probably jamacaru and peruvianus since the spination is different. Thank you

Today I have two mammillarias. First one is most likely m. spinossisima... Yes?

Other one is a mix, there are at least two different plants in this pot, if I'm right I'll be fine with ID of just one.

Hi AnTTun,

Definitely a mammillaria, most likely hahniana. It is possible that the front two may even be m. albata. I am now growing separately 3 plants that were grown together for many years, by another collector, as one plant, looking very much like m.hahniana. When I acquired them about 3 years ago they were quite big specimens,squeezed into a 12" ornate pot. Once they were carefully separated and potted on and had more room to grow they have each developed their own characteristics.
One remains a tall large single headed hahniana, a second tall hahniana has off-set profusely and the third I now believe to be m. albata is also off-setting.

Thank you all for help so far.

Today I have a fero(?) and a steno (or echi..fossu..cac). Steno is rather big (10 cm pot) and globular with quite long strong central spines. Maybe that helps some.

Possible name candidates would be...?

[Aiko]

First one is Ferocactus macrodiscus.

And top view of steno...

Echinofossulocactus erectocentrus

[AnTTun]

Again, thank you both

Two more feros this time. First one grew from seed mix. I kept it because it has two heads. Sort of. Other one could be f. chrysacanthus, but it grows somewhat elongated and spines are not as strong. Correct me if I'm wrong, or confirm my 'ID' please

[anttisepp]

F. rectispinus and emoryi IMHO

[AnTTun]

I was close to disagree with antiisepp's second ID (and I rarely do such thing) but I decided to recheck my 'reasons' first. So I took side pic of my unknown fero:

Then I've checked my young f. emoryi in 7 cms pot

And then my old friend in 12 cms pot

Having on mind that unknown plant grew as a graft for a year or two, comparing ribs and spines shapes, and adding that 'wool' on areoles in comparison, plus keeping on mind that there is quite a variety in such things among feros... its going to be Emoryi The Third

Thank you anttisepp
