Evergreen shrub or tree, up to 12m tall, native to Southeast Asia (Indonesia); often grown as an ornamental for its clusters of fragrant flowers; older branchlets grayish white to pale yellowish gray; leaves 2-5-foliolate, leaflets ovate to elliptic, margin entire; inflorescences terminal or terminal and axillary; flowers frgrant, petals white, narrowly elliptic to oblanceolate, to 2cm; fruit orange to vermilion, narrowly ellipsoid, 1-2cm.

"The principal constituents of the //leaf oil// were β-cyclocitral (22.9%), methyl salicylate (22.4%), trans-nerolidol (11.7%), α-cubebene (7.9%), (−)-cubenol (6.8%), β-cubebene (5.8%) and isogermacrene (5.7%). The most abundant constituent of the fruit essential oil was β-caryophyllene (43.4%). Other major components were (−)-zingiberene (18.9%), germacrene D (8.3%), α-copaene (5.5%) and α-humulene (5.1%)." \\

The major component of the //flower CO2 extract// was manool (29.4%). Further onstituents were phenyl ethyl benzoate (9.2%), E-nerolidol (7.6%), benzyl benzoate (7.0%), phenyl ethyl alcohol (3.3%), and indole (1.2%). \\

HS-SPME analysis of //floral volatiles// emitted by living M.paniculata flowers showed germacrene-D (39.6%) as main constituent, accompanied by caryophyllene (7.4%), bicyclogermacrene (6.9%), E- and Z-β-farnesene (5.9%), (E,E)-α-farnesene (5.8%), β-elemene, δ-cadinene (2.1%) and linalool (2%). Indole (6.6%), (Z)-jasmone (0.3%) and methyl-, ethyl- and benzyl salicylate as well as ethyl-, benzyl- and phenethyl benzoate contribute to the odor of the flowers. \\

"In the F1 flowering stage of M.paniculata, the main volatile compounds were linalool (48.0%) and beta-myrcene (17.5%). However, we found a dramatic change in volatiles composition in the F2 and F3 flowering stages of M. paniculata, with benzaldehyde (47.7% and 46.2%, respectively) and phenylacetaldehyde (19.3% and 25.7%, respectively) being the main volatile components." \\
