Geographical Distributions

Dendrolobium triangulare is distributed from tropical Africa, eastward to India, Sri Lanka, Burma (Myanmar), southern China, Taiwan, Indo-China, Thailand, Malaysia and Indonesia (Kalimantan, Sulawesi, Java, Ma­dura, Lesser Sunda Islands, Timor).


Dendrolobium triangulare is a branched shrub that can reach up to 2 m tall. The branches are terete, lenticellate, striate and nearly hairless. The young parts are sharply triangular.

The leaves are 3-foliolate, with 1.5-6 cm long petiole, occasionally persistent stipules, ovate or elliptical leaflets, wedge-shaped and acute or oblong at base, acumi­nate at apex and entire or slightly undulate. The upper surface is variably sericeous when young while the lower surface is sericeous. The terminal leaflet measures 7-15 cm x 3-6 cm while the lat­eral leaflet measures (2-)6-9(-11) cm x (0.7-)2-4(-5) cm.

The in­florescence is with peduncle, which is less than 1 cm long and 20-30-flowered. The primary bracts measure 2-4 mm x 0.5-1.5 mm. The sepal is 5-9 mm long with white or yellow­ish petal, standard suborbicular or broadly elliptical and elliptical wings. The keel petals are smaller than the wings, with 8-12 mm long androecium, 7-15 mm long gynoecium and densely pubescent ovary.

The pod is ses­sile and compressed. It is (1-)3-5(-6)-jointed which is swollen at the seeds, variably appressed-sericeous where the lower su­ture is more deeply undulate than the upper. Both su­tures are variably thickened. The constricted pod in outline is broad­ly oblong-elliptical or quadrate, measures 4 mm x 3-4 mm and not reticulate.

Ecology / Cultivation

Dendrolobium triangulare is found on a wide range of soils from marshy to dry sandy condi­tions, in forest margins, roadsides, secondary growths, and from 50-1500 m altitude.
