My mom planted this possibly from root stock but I'm not sure. It produces numerous fruit 1"-2" in size but sometimes a little larger. Most are very dark green in color but occasionally a few will lighten its color and yellow slightly. There are no spines and the bark is relatively smooth. The tree is about 10ft tall and wide. I cut a fruit in half and it looks like a lime on the inside but the smell is not very strong. I dabbed a bit of the juice on my tongue but it tasted somewhat bland. It doesn't look like any store lime I've ever seen. Is this just one of those hybrids or some sort of lime I don't know about. More pictures to follow.
