Mammillaria ID

Hello everyone,
I'm new here to this blog and starting off with a question:
Any opinions concerning the ID ?

I think it could be M. haageana, but it doesn't really fit any of the ssp

What does the crowd say ?

Thanks in advance !

Most likely m.haageana sub. acultzingenis. It's probably the camera, but the flower should be more redder for my liking.

yes, that's what I was thinking but the flowers don't match. And no, cam is ok, the color is the way it shows on the pic. It's pale pink with darker pink middle stripe.

The flowers are also quite small and that might point to a connection with M. columbiana (or yucatanensis, ruestii).

woltertenhoeve: Hmmmm, yes, it looks a bit like M. columbiana, but columbiana and its ssp has more central spines (mine has only 2) and also the flower color wouldn't fit. And yes, flowers are pretty small...certainly <1cm in diam.

woltertenhoeve: I got some more opinions and the consensus is that you are right. It's M. columbiana ssp yucatanensis.....thanks !

I know we all pay great attention to how many central or radial spines a plant has before we make a definite id. and then say, oh well this type is variable, if different from it's original description. But your photo shows, if my eyes are seeing right, that it has only two centrals, whereas in Pilbeam's description of m. columbiana ssp. yucatanensis is four or even five. A big difference maybe.

delandmo: that was my original thinking. However, I checked more in detail in found also areoles with 3 spines. The plant is only 2 yrs old,so perhaps, with age, more central spines are produced. What had me doubt the M. haageana idea, was the flower (very small and pink). in any case, what it shows us, is that Mammillaria ID is not an easy feat.

Hello Harald,

I follow Wolter here and agree with Mammillaria columbiana. I was comparing it to my columbiana forms and on a yucatanensis I could find 2 central spines in the apex region if you look closely (picture 1-2). But mostly yucatanensis has 4 central spines. What is known as Mammillaria chiapensis is probably just a form of the subspecies yucatanensis has always 2 central spines (picture 3-4).

Kind regards and merry Christmas
