I'm not good with plants but I hope you have suggestions. This is what is commonly called the lady's slippers but I would love to know the Latin binomial. Flower should be around three inches from the bottom to the top.

I took this photo at roughly around 1500 meters above sea level in an island called Sibuyan in the Philippines last March 2016. They say that flora in Sibuyan Island is quite different from its neighboring islands and thus giving rise to theories on how the island might have evolved over the centuries. It is also sometimes called the "Galapagos of Asia" because of its isolation and high rate of endemism.
