Jelutong
Dyera costulataAlso known as Jelutong Bukit
Jelutong towers above the canopy as one of Southeast Asia's tallest forest giants, anchoring lowland rainforest ecosystems in Malaysia, Sumatra, and Borneo. Its straight, unbranched trunk yields a milky white latex historically tapped to manufacture chewing gum and insulative materials. Paired woody pods split open high in the crown to release winged seeds into prevailing winds.
