Squam or bsbullie have any guesses...Right now I live and help out on a friends farm, there are some 30 varieties of mango,some are topworked and not labeled. This is one of them. Not Glenn , we have some Glenn trees and it's definitely different. I actually like the taste on this one more than Glenn. I'll try to get a pic of the flesh later, phone was inconveniently out of data to take a picture of the one I had yesterday. Little to no fiber. Yellow orange inside. It's a really good mango. Definitely top 10, possibly even top 5 out of the ones planted on the farm...
