Pongamia pinnata.
Synonyms: Pongamia glabra, Millettia pinnata, Derris indica.
Common names: Indian Beech, Honge, Pongam.
Common Hindi name: Karanj.
Plant: 15-25m tall. Deciduous tree with a large canopy.
Leaves: Alternate, compound pinnate leaves, with 5 or 7 leaflets, arranged in 2 or 3 pairs, and a single terminal leaflet. Leaflets 5-10cm long, 4-6cm wide, and pointed at the tip.
Flower: Racemes of white, purple, and pink small flowers.
Fruit: 3-6cm long, 2-3cm wide. Elliptical, thick walled pods, usually with a single seed.
Thought to have originated in India and is found throughout Asia.
Withstanding temperatures slightly below 0C to 50C and annual rainfall of 525dm, the tree grows wild on sandy and rocky soils, including oolitic limestone, but will grow in most soil types, even with its roots in salt water. The dense shade it provides slows the evaporation of surface water and its root structures promote nitrogen fixation, which moves nutrients from the air into the soil.
A thick yellow-orange to brown oil is extracted from seeds. The oil has a bitter taste and a disagreeable aroma, thus it is not considered edible. In India, the oil is used as a fuel for cooking and lamps. The oil is also used as a lubricant, water-paint binder, pesticide, and in soap making and tanning industries. The oil is known to have value in folk medicine for the treatment of rheumatism, as well as human and animal skin diseases. It is effective in enhancing the pigmentation of skin affected by leucoderma or scabies. The oil of Pongam is also used as a substitute for diesel.
Dried leaves are used as an insect repellent in stored grains. The oil cake, when applied to the soil, has pesticidal value, particularly against nematodes and also improve soil fertility.

Dear Nirmal,
a very realistic, well detailed, subtle portrait of this extraordinary vital wild tree, well demonstrating the pleasantly deep shadow that tree offers in hot and dry places parched by the sun.
Thank you! With best regards,
Peter

Hello Nirmal,

Good sharp picture with much detail.

Un'altra bella composizione floreale che si aggiunge alla bellissima galleria di immagini di fiori posti su TN, molto belli i contrasti di luce e di colore, buona nitidezza e bella la prospettiva diagonale di ripresa creata attraverso la DOF. Grazie e complimenti. Ciao Maurizio

Hi Nirmal,

Thanks for introducing the "Indian Beech" ( not a Beech at all). Nice capture.

It would ale to add the family (Fabaceae).

Cheers!

Ishi

Hi Nirmal,

Nice shot of these attractive flowers and an interesting note. Judging by the flowers, the plant must be a member of the Legume family, correct?

Thanks,
John
