Hi,
I think that the first (mammil19) is a pink flowered form of Mammillaria bocasana. I am not sure if it is a naturally found form or a cultivated form.

The second (mammil20), I think, is a form of Mammillaria decipiens, maybe albescens.

By the way, to put your images inline with your message, select the middle link of the dialogue box, or else put the link between square brackets with img between them at the start, and square brackets with /img between them at the end.
Others may like to suggest thier views on these plants, which look nice.

If you have a look at the topic" 3 mammillarias that need identification" you will see that the third plant which is the same as the second plant in this topic was identified as mammillaria decipiens ssp. camptotricha, "bird nest cactus". Therefore which one is correct ?

I think Maurillio has the last two plants in his reply to the "Three Mammillarias....." the wrong way round, I am sure it was just a simple error in numbering the plants, as he knows his Mamms very well.

M. decipiens ssp. camptotricha or the Bird's Nest Cactus has a tangle of spines, often curled, from 2 to 8, all radial.
M. decipiens ssp. albescens has straight white spines, often with no centrals or just one short one.
M. decipiens fma marnier-lapostelle is a bit like a mix of the two.
M. decipiens ssp. decipiens has typically a darker green body and brown central spines.

The flowers are pretty much the same, pale, cream or white.

Thanks for explaining it all Chris. If I understood correctly their ID should be as follows and I would be grateful if you can confirm:

This one should be M. decipiens ssp. albescens

Please need id on these two mammillarias Mammil23

M. decipiens ssp. decipiens

Please need id on these two mammillarias Mammil24

And this last one should be M. decipiens ssp. camptotricha or the Bird's Nest Cactus. In Greek campto means to bend, therefore this would mean bend spines. Also on this one the top spines are a lighter color than the ones at the base.

Yes to your first photo, ssp. albescens.
The second is, I think a rather sparesely spined form of ssp. camptotricha. You can see that some spines are curved (or bent!), but not a lot. I does not have the dark brown central od ssp decipiens.
The last is a cultivar, probably not a naturally occurring form, that, as Maurillio said, I think, earlier, f. marnier-lapostelle.

I am still confused so what I will do is that I will take more recent pictures of the 3 plants and come back again. Thanks for your help.

I'm sorry if I have confused you. If you can explain what you are unsure about, please do post more photos and I will try to help again.

Lets start with M. decipiens ssp. albescens. It has a lot of spines that are straight never bend. Sometimes there is a central spine and sometimes not. The center spine is always longer that the others. Axial spines are whitish while the central spine becomes yellower as it gets to the tip.

This is the first plant and we agree on the naming.

Now to the second plant

It never has a central spine and the number of spines very from 3 to 4 never more (That is on the plant that I have. Maybe on more mature plants there might be more). There are less mammals on this plant (That is fewer than M. decipiens ssp. albescens). There seems to be a space between the group of the center mammals and the outer mammals. The spines are slightly bend. Therefore this one is M. decipiens ssp. camptotricha or the Bird's Nest Cactus.

The thrid plant.

This is much easier since the spines are more curled than the second plant. The spines on the top mammals are always a lighter color than the outer mammal spines. This is Mammillaria camptotricha marnier-lapostollei.There is no central spine. The description can be seen here

You also mentioned M. decipiens ssp. decipiens which I do not have so I cannot comment.

Here is a photo of my M. decipiens ssp decipiens FO-140. The central spines are straight and long, but a little lighter than the formal description gives.
