[img][img][/img][/img]I inherited a cactus when my late Mother died. I never took much notice when
she was alive and could have answered any questions. Not long after she died
I did a lot of research in various sites, based on hours of looking at photos.

I found a site, I seem to think it might have been Kew which asked a lot of questions
in what I considered to be the right way. It asked things like; what shape, did it have the ridges,
if so how many (13), did it have spines projecting from the aureoles, how many (9 - 11), what colour are they (red),
height (6 and half inches above the pot and 2” inside) etc.
The only thing I did not then know was the colour of the flowers, which I now know to be yellow?

I had already found a photo of a cactus which fitted the bill in every way, the complete name of which
I can no longer remember, but the third part of the name was something like ‘klingleriana’, but this
did not appear in many sites. The other closest looking cactus was one of the Echinopsis variants
but not the klingleriana (which I just found while trying to find the name Echinopsis). This looks globose
whereas I would say mine is more globular pyramid (ish).

The one I found, which looked perfect fell down when it was described as having a maximum height of 5
and a half inches, while mine is 8 and a half inches. It is over 40 years old.

See photos. They were taken from above and do not look quite the right shape. Unfortunately, some of the
spine sets got knocked off during the removals.

My Mother went to see my late aunt who lived in Phoenix, Arizona in 1969 and I think she brought some seed back and grew it. Her house was always about 90 degrees F summer and winter

Looks like a Ferocactus to me? I will leave the Ferocactus lovers to name it.

E. stoloniferous or tayopensis is an Echinocereus not an Echinopsis anyway and would have green stigma lobes.

E. klingeriana is an Echinopsis and not your plant

It resembles me Thelocactus (Hamatocactus) setispinus.

There is a short-spined cultivar, Thelocactus setisetispinus f. brevispinus, I think that's what this is. The flowers usually have a red throat, but exceptions are not unknown.

[DaveW]

I don't think it is Thelocactus setispinus, or the form brevispinus since as you say flowers usually have a red throat and an 8 and a half inch tall plant is too large for T. setispinus and more within the realm of a Ferocactus:-

Looks more like a poorly spined Ferocactus (Hamatocactus) hamatacanthus (syn. longihamatus) to me:-
