These two photos are of some unknown seedlings. I planted them a year or so ago and gave up on them. I think they were either calamondin or limequat, but the label was lost long ago. After several months in the greenhouse, lo and behold these came up. The only trifoliate I have is Flying dragon, but these were planted long before I had fruits on my FD.
I have had both calamondin and limequat seedlings before, but I do not remember their having trifoliate leaves.
