Jelutong
Dyera costulataAlso known as Jelutong Bukit
Rising high above the canopy in Asian rainforests, Jelutong is a colossal emergent tree reaching heights up to 80 meters with massive straight trunks clear of branches for much of their length. Its lightweight, white wood is prized for pencil manufacture and woodcarving, while its abundant white latex was historically tapped on a large scale to supply the global chewing gum industry. Trees bloom synchronously across regions, producing fragrant cream-colored flowers followed by large paired pods that release winged seeds into upper-canopy wind currents.

Responsible observation
- Look Up: Scan the upper forest canopy in lowland Asian reserves to spot massive crowns looming above surrounding foliage.
- Spot Tapping Marks: Inspect older trunks for distinctive diagonal scar patterns left by historical latex gatherers.
- Watch for Pods: Look near the tree base for heavy woody pods split into paired horn-like halves that shed wind-blown seeds.
