It's Torbet.
Actually its 'Torbert'
. Though its commonly misspelled 'Torbet'. Was named after the Torbert family of Homestead, who still live(d) there as of recently.
Its a mediocre mango. Gets nice color but the flesh has a fair amount of fiber (Haden-like or worse depending on where its grown). Flavor is mild. I had it again this year for the first time in a while, wasn't as bland as I remembered it but still nothing remarkable.
Its actually a good producer and has a dwarf-ish growth habit too, which are probably the reasons why it made it to the curator's choice list one year.
I have one growing....just cause.
