COMMON cactus list is located in CACTI IDENTIFICATION in the ANNOUNCEMENTS section

The list/pics of COMMON cactus is fantastic and could possibly limit some COMMON cactus ID request. Critical observation of the COMMON cactus list (apologies in advance) - Display the pics before the list instead of the list before the pics. A newbie only looking for a cactus ID is thrown off by a l...

7george, you could be right about the spines. I notice the spines remove easily and have a jacket covering them. Losing them definitely could leave a barnacle looking spot. Also, as you mentioned they could be new spines coming in. Thanks

Picture only. Originally purchased in Italy. Name unknown.

It was doing good in the rich soil it was given to in many months ago. Upon repotting into a mainly inorganic gritty mix 7 weeks ago things have gone south. Seems like a soil issue. The grtty mix being checked with a skewer is still moist after 2 weeks does not sound good. I think you are on the rig...

Ferocactus something. Possibly emoryi?

Thanks Tony.
