I agree with Emydura that is can be Yang-Ji Apple (phillippense x anitum). The great thing about this hybrid are the long petals, which is longer at 20 cm that the average median petal length of either species at 16 cm.
Yes they all have the yellow lip in this cross (as much as I’ve seen), a dominant feature of phils in some hybrids (but not all).WOW i like that a lot....
@emydura , @DrLeslieEe
For folks that have seen many Yang-ji Apples ... do these typically retain a robellini like lip coloration form the philippinense parent?
