yeah this is the worrisome part, as when i did a bit more sleuthing of NMSU’s website, the magnified photo of the second pic posted as alcalde’s thorns look quite the same as ogw’s autumn beauty. And the fruits as well, showing up as relatively large fruits of cylindrical forms with wide girths and relatively flat on one dimension(the z-axis) but broad on the the other dimension(x-axis), while its overall length is relatively long(y-axis).
The same as the ogw autumn beauty that you have, and the ogw autumn beauty that i have.
anyway, encircled below are the thorns enhanced from NMSU’s second photo of alcalde branches Hopefully it was just a clerical error by nmsu website(or error by your alcalde source)
and below are my autumn beauty from ogw, note the fruits and thorns similar to what you have. The thorns are also forward tilting and quite long
