I give you a young mamm candida:
and a slightly older(drum roll for this l o n g name)mammilaria vetula ssp. gracilis cv 'Arizona Snowcap'
Cute! I love the snowcap Mamm, very different. I just adore these cacti, my whole collection is becoming Mamms. Good luck w/them & keep posting!
Wow, Larry, you have some of the most beautiful and unusual-looking stuff! I wasn't going to have more Mamms, and now I have gotten a strong desire for 'Arizona Snowcap.'
