Your Phal. hainanensis is not a hybrid but a species from the island of Hainan, China. The indication of 'Leesburg x Old Dominion' is just an indication of the two different plants he used to create the cross but they are both still the species hainanensis.
Here is a picture of my hainanensis, the exact same one you have
Your second one is a hybrid from the hainanensis and honghenensis which is another Chinese origin phal. I do not know if this grex has been named yet.
