Request for ID : 010111 : AK-2: Again at Nuwara Eliya, Sri Lanka which is at 1892 meters on the 18th
of Nov,2010. Is it some variety of Albizia?


Perhaps Leucaena leucocephala


it looks like Acacia meansii


Are the stems green in colour? This is not *Leucaena* sp.


look like Acacia mearnsii


Looks like black wattle: Acacia mearnsii. Need to check the bark and fruits before confirmation. These trees are very common in Ooty (at 5000 ft) grown on commercial scale. The bark is used for tannin extraction (most valuable vegetable tannin for tanning hides and skins). In fact the wattle extract company is located in Mettupalyam (near Coimbatore) on the foothills of Ooty

… 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).


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,  …, our group member from Coimbatore may be able to throw more light on this species now.


Request for ID : 100611 : AK-1: Taken at Kodaikanal, on the 23rd of Oct, 2008.
Medium trees at higher elevation.
Albizia sp?


I was told by a local person its name as Viscose Cidar. However, I could not correlate it with any botanical name.


The plant in the picture seems to be either Albizzia or Acacia……..not sure


Closest I can think is Acacia leucophloeia


This looks similar to Acacia mearnsii posted by … under ‘Mimosaceae Week’.
Since … has mentioned location as Ooty, and my pictures are taken at Kodaikanal, it could be similar.

This is Black Wattle; Acacia mearnsii

The tree is Acacia mearnsii, the black wattle (Tanner’s gold). In Ooty the most common Acacia sps.

There are plantations of this species and wattle extract is manufactured from the bark in the factory located at Mettupalyam at the foothills of Ooty. The wattle extract is used in the tanning industry for tanning purpose (conversion of hides into leather) .
