Acacia leucophloea FOR VALIDATION :: Jodhpur :: 24 OCT 18

[Dinesh Valke]

Jodhpur  Guda Bishnoiyan Date: October 24, 2018 ... Altitude: about 230 m (750 feet) asl

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

Regards. Dinesh

[Tapas Chakrabarty]

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. 

[Dinesh Valke]

Thank you Tapas ji and Mahadeswara ji 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 ...

Regards.

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

[Dinesh Valke]

Thank you very much Tapas ji for the comment.

From the photos available in this post, to me, the heads are in axillary / terminal panicles.

Mahadeswara ji, unfortunately I have no picture of trunk / bark. But I do recollect it was silver grey.

I would go with Acacia leucophloea.

Regards.

Dinesh

[Tapas Chakrabarty]

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

[Dinesh Valke]

OK, thank you very much, Tapas ji.

Will label the photos accordingly.

Regards.

Dinesh

[Tapas Chakrabarty]

No Dinesh ji,

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.

Regards.

[Dinesh Valke]

Thank you very much Tapas ji for this comment.

I will label the photos to genus level as Acacia sp.

Regards.

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

[Tapas Chakrabarty]

Dear Swamy ji,

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

Kind regards.

Thank you very much Mahadeswara ji.

Clearly different from what I have posted. Many thanks for sharing pics of Vachellia leucophloea.

Tapas Ji, Dinesh Ji,

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.

[Aarti S. Khale]

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.

Thanks very much Aarti ji, for sharing the pictures.

This is Acacia planifrons W&A 

A.Lalithamba

[lalithamba]

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

A.Lalithamba

[Tapas Chakrabarty]

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

[Aarti S. Khale]

Dinesh Ji,

You are welcome!

Aarti

[J.M. Garg]

To me also looks different as per images at https://sites.google.com/site/efloraofindia/species/a---l/f/fabaceae/vachellia/acacia-planifrons

[Dinesh Valke]

Thank you Lalithamaba ji and Garg ji 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 ?

Regards.

Dinesh

[Dinesh Valke]

Thanks very much, Lalithamba ji,

Sincere apologies; I expressed my query more like a question.

Hope this ID resolves to Acacia planifrons.

Regards.

Dinesh

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,

[Dinesh Valke]

I got to know from Pradeep Krishen ji ... 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.

Dinesh Ji,

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.

[J.M. Garg]

Thanks, Dinesh ji 

[Dinesh Valke]

Thanks Aarti ji, Tapas ji and Garg ji.
