Paph. Alma Gevaert note the spelling, it's frequently misspelled! is a complex maudiae type of Paph, used frequently in hybriding.
Paph. Rising Sun is even less well documented. It has 56% Paph. insigne in it's background, as well as villosum, spicerianum and boxallii, but there's a 12.5% unknown, which is tantalizing!
It sounds like some sort of bulldog. That's a term for heavily hybridized complex Paphs. They have a round, bulldog face appearance.
