Help me identify this Fabaceae member
Photographed in Behali Reserve Forest, Biswanath, Assam on 16 October 2018.
The forest type is Semi Evergreen.
Could not find a match or clue as per comparative images at
Flowers appear like those of Crotalaria.
It looks like Desmodium.
It might be Desmodium caudatum syn. Ohwia caudata recorded from Assam.
Yes … I agree with this name.
