Not sure exactly what type of orange this is. These oranges are easy to peel, seedless and seem to come in multiple sizes. The tree has gone crazy this year. It usually didn’t produce ripe fruit until December or January. This year we have ripe fruit here in September. It looks like it will continue through to December. Three years ago it looked like it was on its last leg, but has come back strong and healthy. As soon as it is done fruiting, it will get a hard pruning.
