I was walking all around B&B Cactus Farm
in Tucson and came across this very interesting cactus.
The official name of it is a Mammillaria Parkinsonii,
but I prefer to call it a gray donut cactus. Ha ha!
At first glance, it looks like something that belongs on a shelf of a donut or pastry shop! :)
The blue container helped contribute to the beautiful aesthetics of the cactus as well. -Steve (January 2007)
