38 Stipules minute or 0.
43 Pods as long as or shorter than calyx

This may be Crotalaria prostata Rottl.
Fabaceae (Faboideae) Week_ Crotolaria linnifolia_ 091111PD11 Flora of Orissa:
Place of collection: Ranpur, Nayagarh, Orissa
Habitat: Wild, grasslands, rice fields, forest boundary
Altitude: 100 to 300 m above msl
A small correction: it is C. linifolia (single n). There are two varieties and this looks like the typical one.

Whether it could be Crotalaria albida ?
Looks like Crotalaria ramossisima
To me also it appears close to images at Crotalaria albida Roth and does not match with images at Crotalaria ramosissima Roxb.
Thanks, …, for pointing out.
It is not Crotalaria albida, but it is Crotalaria linifolia L.f.,
