As I don't have a normal T. valdezianus at this time, I'll use this page to showcase a little grafted crest I got from Miles Anderson recently. When I get my hands on a normal one, I'll do a page that's a little more in depth. One thing I'll say for the plant it has very neat spination. It is sometimes included in the genus Pelecyphora. Lucky me I got one with flower buds on it. Beautiful!

Later that summer after flowering
