Gurcharan ji ... to me does look like Acacia mearnsii (my sightings at Shimla and Ooty)
Let us also wait for more validating comment(s).
Description (from PIER): "Unarmed, evergreen tree 5-10 (-15) m high; branchlets shallowly ridged; all parts finely hairy; growth tips golden-hairy. Leaves: Dark olive-green, finely hairy, bipinnate; leaflets short (1.5-4 mm) and crowded; raised glands occur at and between the junctions of pinnae pairs. Flowers: Pale yellow or cream, globular flowerheads in large, fragrant sprays. Fruits: Dark brown pods, finely hairy, usually markedly constricted" (Henderson, 1995; p. 55).
Regards.

Dear sir,
At the outset the set of photographs are very beautiful.
A.mearnsii is cultivated on large scale as a plantation crop in Ooty ( 5000 ft) for commercial purpose for extracting the tannins known as wattle extract (tanners' gold) from the bark for tanning hides and skins. Wattle extracting factory is located on the foot hills of Ooty in Mettupalayam town. I have worked on the photochemical aspects of the bark/extract etc. long back. I am unable to locate the old printed photographs. At that time the digital photography was non- existent in India. The tree looks like one. Nevertheless, Mr. B. Sabapathi ji, our group member from Coimbatore may be able to throw more light on this species now.
