All the photos under Haageocereus (Haageocereus pseudomelanostele) are those of a parodia (notocactus, eriocactus) leninghausii.
I request the photos be re-labeled,and if possible, proper photos of the plant be uploaded instead.
In addition, id like to suggest a revision of photo - pages regarding cacti, since i have observed multiple mismatches.

those are not photos of Haageocereus pseudomelanostele.

It looks like a Parodia leninghausii to me, too.

The best solution for mismatches is to report them exactly as you have done for this plant. If you want to relocate cactus photos to different pages, please speak up when you find something which may be incorrectly identified, and we'll get them sorted out.

We'll wait a couple of days for the photo owner to respond. If she doesn't, we'll move the photos to the correct entry without waiting for her to take this action on her own.

Its been 2 months. Remove photos...
