Nice detail in the highlights Irwin - I think you got it just about spot on!
A very nice plant from what I can see of it - somewhat like a high class Mamm I always thought. . I believe this used to be considered a variety of E. micromeris, has it been afforded full species status now?
You know I have probably seen more cacti than I have at any other time in my entire life, right here. These are quite nice and fuzzy and also like most cactus I suppose prickly. Beautiful shot, though it is just a bit soft looking.
