The world's tiniest cactus--flower or fruit?--Joshua Tree National Park

Last Saturday while William and I were hiking in Joshua Tree National Park across the road from the White Tank area I came upon this tiny cactus tucked beside an outcropping of rock.

I'm looking through my books and information on wildflowers. I'm thinking the red buds are flowers but they look more like fruit. Any thoughts?

They are fruits. Mammillaria for sure, off the top of my head, dioca. Definitely not the world's tiniest cactus, I think Blossfeldia lilliputania holds that title.

Thanks for the tip! Researching further I found that the cactus is called the California Pincushion (Mammillaria tetrancistra)

It's fishhook mammillaria. See the photo at http://www.ipernity.com/doc/18713/1442004

I believe those are flower buds in your photo.

Josh--that's for your help in identifying this cactus. Photos I've found online match with the cactus I photographed. It appears to be a mammillaria tetrancistra, the California Pincushion. Is it the fishhook family? I'm learning!
