I definitely think it looks the most similar to O. dillenii, but I feel it still could be O. littoralis or even engelmanni like you said, it's very difficult to differentiate these species. Does anyone know some sort of resource that clearly states the differences between these species? For exemple I just read online recently that the only supposed difference between O. stricta and O. dillenii is the average number of spines per areole is more than 3, but even then most example photos of O. stricta show a lot of areoles with more than 4 spines. Also the way the fruit forms on this on this cacti is pretty strange, maybe its because they are infertile? Or could it be a trait of the species/variety? IDK
Its not hard. Like I said- look at the spines. They are curved. Very curved. Most opuntias have straight unbent spines. Even those that 2 have it really long. The other one with bent spines is o.chlorotica.
Oh I did not think of that, so the curved spines makes you think its dillenii?

I've had some luck contacting the Desert Botanical Garden in Phoenix for definitive help identifying plants.
I suggest e-mailing their plant hotline address, with pictures, and requesting an opinion from an Opuntia specialist. Turned out to be a great resource.

It is run by a collective of opuntia experts in the US, so for opuntias that are predominantly native to the US they may represent the best collective knowledge, so they may be able to help with an ID as well.
