Fabaceae member ? Check for Alysicarpus ???
Pl. check as suggested by … with comparative images at
May be from some other genus
It is Polygala arvensis the leaf and bud, close up of flower indicates; but due to poor quality of flower it is mistaken as a member of Fabaceae
Thanks, … Looks different to me.
This should be Polygala jacobii Chandrab.
