R. lindbergiana (Smoley)
Different flower from what I suspect is R. lindbergiana, but I'm still trying to identify both plants. If only we had a definitive photo source to work from.

R. grandiflora and an unknown
(left) R. grandiflora. (right) An unknown whose stems are distinctly different from the R. grandiflora. Notice the difference in the number of stigma lobes. Otherwise, the flowers look quite similar.

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.
