English: Palawan represents a bridge between the Sunda Shelf and Philippine bioregions and contains floral elements from both, as well as it own unique elements. There's lots of endemic flora on Palawan but this particular place appears to be endemic to Palawan itself. Endemic flora which are unique to specific regions present opportunities to study the past. Trees and plants always have evolved from previous populations somewhere else, but they ended up getting isolated from other populations, and then drifted to become distinct species in a group. They are not completely unique and will most often still breed with other species in the genus. This Palawan place might have had an isolated microclimate that kept it unique for thousands of years.
