One of the first cactus to come home to 1346 from the California Cactus Center. I think it’s a rebutia, but any additional IDing info would be most appreciated. No Tom, it’s not dead. What I find most appealing is its solitude. Most rebutias I’ve seen in the few weeks I’ve been looking them up seem to be photographed either blooming (in which case you can’t see much at all due to the large colorful flowers) or clumped with many growths… so who knows. The cactus center crew thought perhaps it may have been a very old plant… but again who, knows. I like it. Very much.
