Mammillaria spinosissima or Mammillaria meyrani ?

Hi cactus friends.
This afternoon I surprised with 2 cacti, of someone who has been to Ikea.
Do you have a suggestion how these 2 cacti are called?Mammillaria spinosissima Mammillaria meyrani or Is it???
PS. picture 1 and 1A are the same cacti.
Thanks for your effort.
Joseph

I think second plant (on 2 pictures) is Bombycina... Both of them need more sun and less nutrients and water...
Be careful with introducing to sun in the begining

Goodmorning MMartic,
It would be a good link for a Bombycina!
But the variation is very large in this. Has this Bombycina a subname ? or should I wait for the flowers? I think the 1st picture is a spinnossima species..?
Have a nice day,
Greetings Joseph.

No.1 is most likely m. meyranii and No.2 is m.Bombycina, no other subspecies name . Both plants appear to be growing in a peaty or coir based compost, used by plant nurseries to promote quick growth, that is why plant No.1 looks bloated. I would change the compost asap. Could lead to an attack of sciara fly and very difficult to re-wet if allowed to dry out.

Goodafternoon Delandmo,
Thank you so much for your good advice!
For both cacti is the ground already been replaced by original cactus soil.
Nice day!
Joseph.

Dear friends, I recently received this email from a friend:
Hi Joseph, is not up to you, I don't find much on google.
While in the in the photo encyclopedia, the meyranii has clearly hated thorns!!
But in the book by Backeberg is no crochet thorns mentioned!!
The picture in my book has field number Reppenhage 968.
The flowers will provide the answer!!
Greetings B.

So best friends, I understand any anymore, so like your help!
ITEM IS PHOTO nr.1

Hi,
Rep 968 is m, meyranii, and your plant No1 appears to have two central spines. one pointing upwards and one pointing downwards, which is what is expected in m. meyranii. No hooked spines! Your photo does show some hooked spines when looking carefully. Another plant that could possibly be yours with hooked spines, but would call for a least 4 central spines (3 upper and 1 lower and longer) and in the same series of the polyacanthae is m. duoformis complex, maybe synonym m. hamata.

If I may butt in here. I think that trying to identify a plant from Ikea is not easy. It is probable that it is grown in a huge nursery, with seed that is of uncertain origin, and more than likely of hybrid origin.

M. meyranii is not a common species, and I would doubt that Ikea would buy such a plant - or rather that a nursery would produce plants in such numbers as to satisfy Ikea demand. It is much more likely that it is of the duoformis type.

In the Polyacanthae series, species have been described which have straight spines and others with hooked spines. The reality is that hooked spines are a variable feature. Just look at M. rekoi to see how variable the hooked central spine is.

If you really want to know what species a plant is, you need to know where it comes from, which means a field number and a reliable grower.

I would label the first plant as M. sp. Nunezii Group.
