WHen I see fruit labeled pomelo at my local Whole Foods, they look like green grapefruit. Another name for Pomelo is "Chinese Grapefruit." I think I've read that Pomelos are one of the ancestors of a lot of the citrus that we eat. There's an Asian family in my neighborhood that has a Pomelo tree in their yard. Their pomelos range from fat ovals to more pear shaped.

I think that's just a pomelo, maybe a different tree with different lineage or different growing environment or different care or slightly different variety.
