Name: Daisy I Reno, Nv (Zone 6b) Not all who wander are lost
No, I'm not understanding either. The plant is Mammillaria karwinskiana ssp. nejapensis and it is listed in Catalog of Life as an accepted name. As mcvansoest pointed out, the description is also correct.
Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and proclaiming...."WOW What a Ride!!" -Mark Frost
