correction please. proper spelling of one is ACACIA tortilis. tortillas is not even a synonym. it seems it was a mistake somewhere and the silly people copy pasted, perpetuating the mistake, tortillas means roti. thats why i was confused and went looking

Certainly not A.planifrons , which I have seen in Guindy National park, Chennai

Please check for the characteristic curly pods and spine arrangement for ID

Pl. check comparative images at 

To me appears close

¿ Acacia leucophloea ?  
Dear friends,
Please help validate the ID.

This is not Acacia leucophloea as the heads are in axillary fascicles.  We need close up of the leaves and leaflets and need to know about the pubescence, if any in additions to the fruiting photographs.  This is somewhat comparable to Acacia tortilis (now Vachellia tortilis) but I do not see the elongated spines anywhere.  Could this be an introduced species?

For me  you need to check the bark as well. Acacia leucophloea is easily identifiable by the bark which is whitish to yellowish grey. 

Thank you … for validating.
Tapas ji, you must be correct about introduced species – this tree is planted in premises of Rajasthan Forest Department’s tourist post at Guda Bishnoiyan … an important lake where migratory birds make a stopover.
Mahadeswara ji, thank you for the bark characteristics; I do not know why – I had the feeling that all of trunk, branches of A. leucophloea are of silver grey.
I will correct my notes in flickr to very simply Acacia sp. – because at present I do not have photos with required aspects.
Here is one cropped version, if at all it gives any hint to Tapas ji …


I have no hesitation in calling this as Acacia leucophloea provided that the heads are arranged in axillary and terminal panicles.

Thank you very much … for the comment.
From the photos available in this post, to me, the heads are in axillary / terminal panicles.
…, unfortunately I have no picture of trunk / bark. But I do recollect it was silver grey.
I would go with Acacia leucophloea.


In that case Vachellia leucophloea (Roxb.) Maslin et al. is the accepted name.

OK, thank you very much, … Will label the photos accordingly.

No …, Acacia leucophloea will have different inflorescence type.

I am not satisfied with this identification.
Possible the images posted by you belong to a species not recorded so far for India.

Thank you very much … for this comment.
I will label the photos to genus level as Acacia sp.


I agree with … I am posting a few pictures of Vachelia leucophloea taken in Mysore. Hope these photos are of Vachelia leucophloea.

I am very happy to see these beautiful images of Vachellia leucophloea.

Thank you very much … Clearly different from what I have posted. Many thanks for sharing pics of Vachellia leucophloea.


I have also posted Vachellia leucophloea from Delhi and Bangalore earlier, with close up of the pods and bark.
You may need to search in Acacia leucophloea.


Here are the pictures.

This is the first time I am trying to attach a file directly on the group and not through my email.

This is Acacia planifrons Wight&Arn.,In our college we had this plants.

I beg to differ. Where are the long spines of planifrons?

To me also looks different as per images at 

Thank you … for Acacia planifrons … we do see recurved spines on nodes and in axils, but the conspicuous, straight white long thorns are not seen on the branches. Any reasoning ?


There is one tree in our college that looks same, which produce circinate pods, the bract at the peduncle is near the base, flower head white, pinnae 2-3 pairs hence I thought it to be Acacia planifrons

Thanks very much, …,  Sincere apologies; I expressed my query more like a question.
Hope this ID resolves to Acacia planifrons.

I got to know from … that the posted plant is Vachellia tortilis.
The Forest Deptt calls it Israeli babool….the spines are erratic – the straight ones more or less present, but unevenly.

This is a common plant in Oman. I had posted earlier.


How nice. Actually it is growing very fast even in xeric conditions. Cultivated in many places in Jodhpur area. A good sand binder also. The fruits would have revealed the identity at once.

Vachellia planifrons and Vachellia tortilus : 3 posts by 2 authors. Attachments (6)- 4 of this species. 
After scrutiny of my specimens I am attaching Vachellia planifrons and Vachellia tortilus

Both plants are in umbrella shaped, pods circinate, flower heads white; but planifrons have long straight thorns here and there, flower heads are clustered in axils; Vachellia tortilus never produce long straight thorns, flower heads are solitary.
