| Dipterocarpus ochraceus | |
Dipterocarpus ochraceus is a tropical rainforest tree endemic to Sabah. It is known from the ultramafic hills in the Ranau district. [2]
Dipterocarpus ochraceus grows up to 45 meters high, with a trunk up to 1.2 meters in diameter. [1]
Dipterocarpus ochraceus grows on ridges in hill forests from 600 to 900 meters elevation, typically on ultramafic soils of intermediate fertility. It is typically an emergent tree, rising above the forest canopy. It is absent from the Gymnostoma nobile -dominated forests which grow on the most nutrient-scarce ultramafic soils, and also absent from hill dipterocarp forests on more fertile soils where Shorea parvistipulata is predominant.

Dipterocarpus acutangulus is a species of tree in the family Dipterocarpaceae. The species name acutangulus is derived from Latin and refers to the ribs of the fruit calyx tube. It is native to peninsular Thailand and Malaysia and also Borneo, where it is locally known as keruing merkah or keruing beludu. It is an emergent tree up to 60 m tall. The tree occurs in mixed dipterocarp forests found on sandy and sandy clay soils on coastal hills and inland ridges, up to 1000 m elevation. It occurs in at least one protected area.
Dipterocarpus humeratus is a species of tree in the family Dipterocarpaceae. The species name humeratus is derived from Latin and refers to the articulated petiole. D. humeratus is an emergent tree, up to 50 m tall, found in mixed dipterocarp forests on well-drained clay soils. The species is found scattered or semi-gregarious on undulating land and clay ridges below 700 m elevation. It is found in Sumatra and Borneo and occurs in at least three protected areas.
Elaeocarpus inopinatus is a species of flowering plant in the Elaeocarpaceae family. It is a tree endemic to Borneo where it is confined to Sabah.
Atuna cordata is a tree in the Atuna genus of the family Chrysobalanaceae. The specific epithet cordata is from the Latin meaning "heart-shaped", referring to the leaf base.

It is one of the rarest and most endangered of all dipterocarps, with a population size of only twelve individuals, threatened mostly by habitat loss.
Shorea agamii is a species of plant in the family Dipterocarpaceae. The species is named after J. Agama a one time forest officier in the Sabah Forestry Department. Two subspecies are recognised subsp. agamii and subsp diminuta. The subspecies name diminuta is derived from Latin and refers to the smaller leaves of this subspecies.
