Thank you for creating the flag Najera.

I suggest that we make a table to compare the taxa as was done with the other cacti in order to fix not only what is discussed in this paper but in others and with other taxa non mentioned
I think unfortunately these authors do not worked extensively with Mexican Opuntia, I think M.B. and M.C. are working on with choyas/grusonias by now, there is no consensus for Mexican Opuntia species and several genetic works suggest there are more cryptic taxa waiting for being discovered/described, I suggest to use Dra. Bravo work (Cactaceas de México vol 1) as the main basis for Mexican Opuntia, plus the recent descriptions and discoveries from the recent years.
Yes, the works of Baker, Cloud-Hughes, Pinkava, and others are primarily for the western USA Cylindropuntia and allies. I certainly agree with your suggestion for the Mexican Opuntia.
so then we should maintain C. rosea as a true specie and so....
this was discussed time ago
Hello Pedro,
I do not know the group. @martha_gonzalez_elizondo perhaps may help.
Saludos 😊
Baker & Pinkava place C. rosea under C. imbricata.
I think that working Opuntioideae is a work of great patience, in my opinion the base work is Bravo-Hollis 1978, but we must know other works, I remember that teacher Bravo told me that the more you study a group if you do not with a broad criterion, you just get troubles. A good review of Opuntia in a broad sense is Crook & Motran (Bradleya 1995, etc). We must rely on the naming rules, know how to distinguish valid, invalid and accepted names.

Recent works by specialists of the group Marc Baker, Michelle Cloud-Hughes, & Donald Pinkava have been the culmination of years of work and field study with the plants of the Opuntioideae. (Ex. https://www.researchgate.net/publication/271761633_Chromosome_Numbers_in_Some_Cacti_of_Western_North_America-V). I believe deviations are necessary, and I’m curious as to what others think.
