I know I am blowing up this forum, but can you ID these for me? Haha thank you!

It could be Coryphantha. Definitely not Mammillaria.

Sorry, Daisy, but I disagree. Number 1 looks a lot like one of the Mammillaria haageana subsp. I think #2 is also a Mammillaria, having a harder time putting a name to it and no time to dive into my Mammillaria books, but they look way more like Mammillarias than Coryphanthas to me. #2 especially also looks like it could use more light, but both are looking nice an healthy.

Lindsey, can you tell us where you got them? Cactus nursery, big box store, on-line? I rarely see Coryphanthas at the big box stores in my area, plenty of Mammillarias though.

Thank you!!! I just bought them a few days ago....from ALDI!!! Hahah I normally get mine all from a nursery, but while I was grocery shopping I saw they had cacti and succulents, so I bought every single one they had!

I suggested Coryphantha for the first one because I can't see any tufts between the tubercles. And because the central spine does not have a hook. It doesn't seem very Mammillaria like to me without those two features. I know not all Mamm's have a hook (but the ones with a central spine like that do seem to have hooks) but they do all have tufts or bristles or... between the tubercles.

I said #2 was a Mamm. assuming it is the one listed separately later. If not, looks like there are tufts down there so Mammillaria.

I can add more pictures that are up close of each! (:

That would be great!

Here are some closer images!

I think I see some tufts between the tubercles. If my eyes are not playing tricks, its a Mammillaria. But wait... that's the second cactus with light central spines. I thought that was Mammillaria.

Please add close ups of the cactus with the dark central spines.

Cactus #1 in the blue pot:




Cactus #2 on the brown pot:

Compare your brown pot one to this:

That does look a lot like that picture, Thijs!

Looking at both plants, they could be different subspecies of the same Mammillaria species... the number of central spines is variable among them

what is the species in your photo?

It is Mammillaria haageana. Not quite sure about the exact subspecies, most likely ssp. san-angelensis.

Thank you so much!!

Mammillaria have only one characteristic they don't share with any other genus: tufts or bristles or ? at the base of the tubercles. That is were the flowers form. If you see any little tufts, bristles... at the base of the tubercles, it is a Mammillaria.

Its now up to you Lindsey. Your photos are great but you are looking at the plant. A photo can't replace that. Are they both Mammillaria?

Daisy

Is there any way you could show me what these tufts look like on a mammillaria? Thank you!

Good point, Daisy!

Look at the 2nd detailed photo of your first plant. Top center left between the spines you will see a bit of wooly white 'hair' in between the tubercles - which carry the spines.
In your second plant it is not as easy to see but it looks like it may have it too.

Some Mammmillaria have this wool in profusion and year round, whereas in many others, these tufts of wooly white hair tend to be way more pronounced as the plant builds up to flowering, flowers and then shortly after, in the non flowering period they diminish in prominence or sometimes almost completely disappear until the next flowering cycle.

The M. haageana I posted a picture of shows a very small increase in the tufts when it flowers, but it is pretty sparse. However this is another one - just a different ssp. (likely ssp. elegans) that clearly shows the tufts very prominently in the band with the flowers and much diminished outside of those bands.

Okay I have examined both.... and the verdict is that they are both mammillaria!
