Doesn't look like M. geminispina, but I'm not sure what it would be. Got very bristly radials but I don't think its M. hahniana. Got to hit the reference books!

It seems that there is a long-spined form of M. geminispina that looks a lot like this. Sometimes called M. geminispina var nobilis.

The flowers look more like a close relative such as M. klissingiana, they're quite pale for M. geminispina.

Flowers do look a bit pale for geminispina, although there is some variation, and the spines are a bit dark also. Will post a pic of var. nobilis later, when Photobucket is back up.

Hi,
I don't think this is a M. geminispina. M. geminispina has black tips on the white spines and I don't see these on your plant. The radial spines look too long as well. On the photo below is my long-spined geminispina.

Hi friends, I take a complete tour in Mammillarias page and I don´t get a match for geminispina, one for the long and thin spines, second for the pale flowers and third for the radial spines. Trying to get into M. varieaculeata is hard too. Maybe It is a hybrid. Thank you for your help

Reminds me of a young M. dixanthocentron. Or even a young M. muehlenpfordtii.

I don't think its M. varieaculata.

Here is a cutting I'm striking from a friends geminspina v. nobilis.

Here is a shot of my own plant of Mammillaria geminispina var nobilis.

It helps a lot friends, I have several cacti ID like M. geminispina
#1 {{gwi:493262}}

#2 {{gwi:493263}}

#3 {{gwi:493264}}

#4 {{gwi:493266}}

And now probably this one

They're all nice little plants Alfonso, 1, 2, 3,&4 are all forms of geminispina, I like the upward curving spines on #3.
It doesn't matter if you can't ID the other, it's a lovely little plant just the same, I'll bet it had geminispina for a mammy or pappy though, and it's almost wooly-like as well.

Cheers mate, CP

Let me throw this into the mix. Don't know its exact title. Mammillaria geminispina (Short spined form)
