It is also an inelastic natural latex produced from the sap of these trees, particularly from the species Palaquium<unk> . Chemically,<unk>  is a polyterpene, a polymer of isoprene (trans-1,4-polyisoprene).

The trees are 5–30 metres tall and up to 1 metre in trunk diameter. The leaves are evergreen, alternate or spirally arranged, simple, entire, 8–25 cm long, and glossy green above, often yellow or glaucous below.  The flowers are produced in small clusters along the stems, each flower with a white corolla with 4–7 (mostly 6) acute lobes.  The fruit is an ovoid 3–7 cm berry, containing 1–4 seeds; in many species the fruit is edible.
