I made the drive down to Grigsby Cactus in Vista and came home empty handed because their business hours on a Saturday are 9am - 2pm and I didn't make it (it took 3.5 hours in heavy traffic). So I just rustled up these between an eBay vendor I like and local vendors.

The Mein Leibling and canaliculata were bursting from their 8" pots, rhizomes poking out the bottom drainage holes...so I repotted them in 10.5" pots. The variegated one doesn't resemble whatsoever the other cylindrica I have or have seen (no channels in cylindrica leaves like this one has) and the ID tags at this nursery are often spelled wrong, absent, etc. so chances are it's wrong but it's a big, heavy thing, the smaller leaves in the pot don't show variegation at all for some reason. The nitida has striking contrast and is smooth on one side and sandpapery on the backside of the leaves. Mein Leibling doesn't resemble the other trifasciata plants leaves I have - these are very thick, the whole plant is massive. It was the last one.
