FREE: Paper Spine Cactus RARE rooted plant

The listing, Paper Spine Cactus RARE rooted plant has ended.

Auction is for one, rare, rooted already, stem. Like the one in the 2nd photo, but not the same. Photos are internet examples of different sized plants.
This is one for the plant collectors. You wouldn't be likely to find one in a store.
I may list two, but likely only one, as I don't have many myself. We'll see how the bidding goes.
