In need of ID

Hi,
Here are two that need Id's.


This one is winter hardy, it is in the collection of our Slovenian society president. She would like to find out what it could be. Any Ideas.


Sandi

The first one is something from the haageana group, but don't know exactly which one yet.
Your second plant looks like matudae, but without flowers it is very difficult to ID. It even could be marnierana ( belonging to grahami-microcarpa group), it is very similar with a plant I have.

Hi Hugo,
The second one. It is winter hardy and it takes -17 degrees celsius in the open. I'll ask for a closer picture. I'll ask if she has pictures of flowers.

Sandi

I suspect that the second one isn't a Mammillaria, Sandi, but a form (of which ther are many) of Escobaria vivpara. This comes from the USA and forms exist from New Mexico right up ito Canada, and can survive really low temperatures that a Mammillaria is most unlikely to do.
If so, it should have pink-purple flowers.

Hi again,
Ok I got a close up of the spines. She said it hasn't flowered yet. It is 6cm high.

Hello Sandi,

The more I see the second plant the more I'm convinced that this is M. matudae.
