    41 Pods much exserted , 20-35 seeds
      42 Leaves villous beneath; bracts often 3 lobed; pods subsessile  ….. C.mysorensis
      42 Leaves appressed pubescent beneath; bracts simple; pods shortly stalked …. C.ferruginea
38 Stipules minute or 0.
  43 Pods as long as or shorter than calyx
    44 Calyx to 0.8 cm long; upper two lobes connate except at tip; pods globose … C.linifolia

Id please A crotalaria Spp.
At Sagargad, Alibag

This may be Crotalaria prostata Rottl.
Ref: Flora of Mah., Vol II pg:42.  Leaves description match: subsessile, oblong or oblong ovate, rounded at the apex, usually oblique or cordate at base. Cannnot make out if surface has  silky yellowish or yellowish brown hair  to match the description but calyx 3-4 mm long densely hairy description matches with first two pic. Small flowers, Corolla yellow not exserted.

Crotalaria linifolia

Family: Papilionaceae
Place of collection: Ranpur, Nayagarh, Orissa
Habit: Herb
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

Thanks, …
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.
