But we are not talking about wimpy spines here....
I can see size and lenght variation and colour change at my barrel cacti during summer and winter....but this goes beyond that...
Bottom line is, if it were any ferocactus ive seen, it still maintain those hooks and hard spines, only they would be shorter, less formed and discolored...
Looking at the picture over and over, i cant see something resembling a ferocactus areole with a thick central spine, its simply as wimpy looking as the rest...which shouldnt even be shaped or arranged like that in the first place
As for the color, its also strange... I dont know a lot of barrels with black spines.....most of them are way different thant this...
Only one i did find to remotely match this is ferocactus lindsayi and i cant find a picture of a really old one....
