The new name of this plant according to the plant list (http://www.theplantlist.org/tpl/record/ild-32297) is Archidendron bigeminum (L.) I.C.Nielsen.
The pod and the leaflets are not that of Entada rheedii.

Albizia ¿ species ?

Dear friends,
The large panicle of dishevelled flowers are ditto Albizia odoratissima. The size of leaves and of the 4 pairs of pinnae match that of A. odoratissima, however the leaves are not twice-compound. It is as if the 4 pairs of pinnae have missed splitting further into 12 – 18 pairs of leaflets!

Archaedendron monodelphum

Yes, I think the name Archidendron monadelphum fits here.

Thank you for the ID suggestion, but couldn’t find a match in Acacia sp., and here it is very rare,

Looking at the leaves noticed later, it is not Acacia but some other Fabaceae !

Please check Albizzia !

Same happened to me also, and the leaf arrangements documented in second visit,

Yes, it is Albizzia sp., thank you so much

I am conducted several visits to get an erect anthers’ image, but it was downwards in morning also,

It looks like Archidendron bigeminum

Archidendron species. Check Kerala plants for confirmation. I have seen this in Bhagamandala area Coorg. I remember it as a species of Pithecelloium. Now the name has been changed.
Thanks … for the lead.
