I have identified the tree in Boro-boro springs at Monterry Resort in Bgy. Alangilan, Bacolod City. This tree has tambis looking fruits, but is more fleshy. This post supersedes a previous one on makopa.
The photos in Dr. StuartXchange is of tambis, showing these two fruits are easily confused with each other.
