Botany
Albizia lebbekoides is a small to medium-sized tree, 8-15(-32) m tall, trunk up to 40(-80) cm in diameter; branches terete, glabrous, with grayish bark. Leaves alternate, minutely stipulate, bipinnately compound with 5-13 cm long rachis provided with glands near base and top; petiole 2.5-6 cm long; pinnae in 3-8 pairs, with glandular axis, 5-15 cm long; leaflets (5-)15-25(-35) pairs per pinna, (narrowly) oblong, 6-20 mm × 2-6 mm, asymmetric and truncate at base, mucronate at apex, sessile. Flowers in axillary up to 18 cm long panicles composed of 10-15-flowered heads; calyx narrowly campanulate, very small; corolla tubular, 3.5-5 mm long, 5-lobed; stamens numerous, 7-10 mm, filaments united into a tube; ovary superior, sessile and glabrous. Fruit a strap-shaped dehiscent pod, 7-15(-20) cm × 1.5-2 cm, glabrous, chartaceous and dark brown. Seeds up to 12 per pod, obovate or suborbicular, 4.5-7 mm × 3.5-5 mm × 1-1.5 mm, areolate. Specimens aberrant with regard to the width of the pod (up to 2.8 cm), and the size of the leaflets (up to 27 mm × 14 mm) occur on the Lesser Sunda Islands, but no varieties are recognized. (4)

Constituents
- Study for tannins yielded: bark, 11.04 % extraction (w/w), concentration 150.00 mg/g; branch, 3.93% (w/w),  concentration 17.00 mg/g. (3)
- Study of hexane extract of leaves isolated a new pentacyclic triterpenoid with an oleanane skeleton. Structure was determined as 3ß,16α-dihydroxyolean-6(7),12(13)-dien-28-oic acid. (5)

Parts used
Bark.

Uses
Folkloric
- In Cambodia, bark used for treatment of colic and diarrhea.
Others
- Dye: Provides a red dye used for coloring cloth, known as soga tekik in eastern Java. (2)
- Tannin: Yields tannin. In Java, occasionally used to tan hides and fishing nets. (2)
- Fermented drink: In the Philippines, tannin-rich bark use in the manufacture of fermented drink from sugar cane, basi.
- Wood: Used for indoor construction.

Studies
• Antioxidant / Bark: Chemically-induced oxidative hemolysis is usually associated with formation of Heinz bodies-insoluble precipitates within RBCs, indicating oxidative destruction of hemoglobin. Study evaluated 21 Thai mimosaceous plants for antioxidant activity by Heinze body induction in invitro model. Albizia lebbeckoides bark exhibited 58.90 % Heinz body inhibition. (3)
• Pentacyclic Triterpenoid / Leaves: Study of hexane extract of leaves isolated a new pentacyclic triterpenoid. (5)

Availability
