Thank you Skopjecollection, you are indeed right, it is a Coryphantha garessii. I just looked it up. Thank you very much for the fast and accurate response.
Yes it is a Coryphantha sp. but you are going to have to wait until it blooms to identify it truly and correctly past the generic level. I have a C. sulcata that looks pretty identical at this stage.
Thank you to you as well Smotzer. Wow, I am brand new to this forum, and the community on it is very supportive and responsive. I will most definitely have more questions coming.
