I recently went on a walk around Bukit Mentiri, and it is splendid to see that lots of the trees are labeled, not just with the scientific name but also often with the local names. For example, in the case below, the name of the tree is given in Kedayan and also Iban.
However, it is a pity that the labeling isn't a bit more accurate. Saurauia is a member of the family Actinidiaceae (See this Wikipedia page), not Fagaceae (it is not an oak tree).
