Interesting. So it's possibly a maha doc mai :-). Once you can eat the matured fruit, you'll know for sure.

May be a Luk Rong Won

I planted out this culitvar at least three times in my yard from three different, well respected nurseries.  They are very variable in fruiting quality.  The best thing you can say about the fruit from this oft' misundestood variety is that there is considerable surpirse when it finally sets some fruit.  Sometimes, the surprise turns to disappointment and anger.  Other times, it smoothes into reasonable happiness and mango satisfaction.  May yours bring you the latter.
