Cactus plants of genus Frailea re known to be cleistogamic in many occasions  but no Cleistocactus is really cleistogamic or even self-fertile.The small opening of those flowers, adapted for hummingbird pollination, resulted in confusion and name misapplication.

Stenocactus crispatus

When it comes to Stenocactis species confirmation I'm always in great doubt, unless it is S. coptogonus or S.vaupelianus that are reasonably distinct. Everything else could easily go as forms of S. multicostatus, as the borders between the species are fuzzy.
Stenocacti are among the most sun loving and heat tolerant cacti, and the strongest spination will develop only under the most unforgiving sun.
