Alysicarpus ¿ species ?
Not sure whether the aspects seen in two photos help in getting to species ID.

Does look like one, sir. but a point in the fabaceae key states that "Glumaceous calyx, twice the pedicel length or more" this is not true in the against" Calyx not glumaceous, less than half of pedicel length" which seems to be true in this photograph will indicate that this is a Desmodium spp.
Pls correct if wrong, I am not a 'Taxonomist' and may have got things in the wrong sense :)
Looks like Alysicarpus longifolius.
Kindly check for Alysicarpus tetragonolobus Edgew....
Thank you very much Varun ji for the hint of Alysicarpus tetragonolobus.
