Big mystery

This plant came named R. wercklei but does not match any photos in The New Cactus Lexicon. Britton & Rose mention R. wercklei Berger. Kakteenk. 16:64. 1906, but this specimen doesn't match the drawing in the book. One expert's comment is that this may be an unidentified variety. Since the original local is unknown, this exists only as an oddity.
