For me it is difficult to evaluate the photo of the site, I was on an expedition and we found Pouteria Bullata, it has wavy leaves, well marked, brown flowers, rust color, the fruit darkens quickly, the pulp is a bit dry with large seed, a light taste of milk and sugar.
By the photo I think it is a Regular Pouteria Torta, but as I said, ABIURANA is a generic name here in Brazil, several pouterias we use this name, Guapeva, Guapeba, Bapeba, Bapeva ... all this generates doubts giant!
I'm just saying this to friend, do not buy one kind and get another!
Oh, interesting. I am hoping for the Abiurana that is slightly more cold tolerant than Abiu, as described here:

Is that what you have?
If Helton has it correctly labeled as bullata, then probably mine is different, as i think it is torta. But if Nelesedulis is correct, then bullata is not very good tasting, and the one i have is quite good. Don't know about its cold tolerance.
