Lula that I'm used to have a definite bell shape to them. That could be Lula. The telltale sign if you are on the fence is that Lula is SWEETER than most
I have seen many Lula trees fruiting. Some have necks of varying lengths and sone have a stump as in the picture above. What is the giveaway to me is the size if t ge seed (from the cavity), flesh color and consistency and the skin texture. I know of no other Florida grown avocados with that skin texture.
I will say that it is very early in the season to have a ripe Lula. In Florida, at least Southern Florida, Lula season is December through January and can even hang into February.
