I have three of these poncirus trees and two producing flying dragon. They all produce the same fruit except the dragon fruits are generally a little smaller. It has the oil that sticks to teeth, but I think it makes good marmalade after processing, but it’s the only poncirus fruit I’ve ever sampled; however, I kind of doubt it’s any kind of hybrid. If it’s one of the “better” quality poncirus, I’d have no way of knowing.
